An isomerization catalyst is provided, along with corresponding systems and methods, which provides improved isomerization for bio-derived feeds in reaction environments where by-products from deoxygenation are present. The catalyst provides unexpectedly increased activity and/or selectivity in situations where, for example, a deoxygenation effluent is cascaded to the isomerization catalyst. Additionally, the isomerization catalyst can assist with reducing or minimizing hydrogen consumption during isomerization. The increased activity, stability, and/or reduced hydrogen consumption is achieved in part based on using a dispersion agent when adding base metals to the catalyst. In addition to the base metals, the catalyst includes a zeolitic framework structure suitable for isomerization.

Isomerization of biofeeds over base metal catalysts

Systems and methods are provided for reducing hydrogen consumption during deoxygenation of bio-derived (or at least partially bio-derived) feedstocks. The reduced hydrogen consumption is achieved by performing the deoxygenation in the presence of a bulk multimetallic catalyst and/or in the presence of a base metal dewaxing catalyst having reduced metal stack heights. Additionally, due in part to being able to reduce or minimize hydrogen consumption, the heat release during deoxygenation can also be reduced, thus allowing a smaller catalyst volume to perform deoxygenation.

Reduced H2 consumption during deoxygenation

Systems and methods are provided for production of renewable jet fuel and/or jet fuel blending component fractions. The systems and methods provide for formation of jet boiling range fractions via hydrodeoxygenation and catalytic dewaxing of bio-derived feeds. The systems and methods for reducing or minimizing recycle and/or forming only a jet boiling range product and a lower boiling range product can be facilitated based on selection of a suitable feedstock and/or based on selection of suitable reaction conditions and catalyst for the catalytic dewaxing.

Renewable jet production

Systems and methods are provided for expanding the operating envelope for an FCC reaction system while also reducing or minimizing the net environmental COemissions associated with the FCC reaction system and/or the resulting FCC products. In some aspects, reducing or minimizing net environmental COemissions can be achieved during processing of unconventional feeds, such as feeds that are traditionally viewed as having insufficient tendency to coke in order to maintain heat balance within an FCC reaction system. In other aspects, this can correspond to expanding the production of diesel within an FCC reaction system by modifying the reaction conditions in a manner that can cause a reaction system to fall out of heat balance (relative to the heat needed to maintain a target operating temperature) even when using conventional feeds.

FCC processing with reduced CO2 emissions

Systems and methods are provided for increasing the yield of products generated during co-processing of biomass oil in a fluid catalytic cracking (FCC) system. The systems and methods can allow for increased yield by reducing or minimizing formation of carbon oxides, gas phase products, and/or coke yields during the co-processing. This can be achieved by adding a hydrogen-rich co-feed to the co-processing environment. Examples of hydrogen-rich co-feeds include high hydrogen content vacuum gas oil co-feed, high hydrogen content distillate co-feed, and/or high hydrogen content naphtha co-feed. Additionally or alternately, various types of fractions that contain a sufficient amount of hydrogen donor compounds can be used to reduce or minimize carbon oxide formation.

FCC co-processing of biomass oil with hydrogen rich co-feed

FCC processing with reduced COemissions

Systems and methods are provided for improving product yields and/or product quality during co-processing of fast pyrolysis oil in a fluid catalytic cracking (FCC) reaction environment. The systems and methods can allow for co-processing of an increased amount of fast pyrolysis oil while reducing or minimizing coke production for a feedstock including fast pyrolysis oil and a conventional FCC feed. The reducing or minimizing of coke production can be achieved in part by adding a low molecular weight, non-ionic surfactant to the mixture of fast pyrolysis oil and conventional FCC feed.

FCC co-processing of biomass oil

A method may include: providing bio waste stream wherein the bio waste stream comprises at least one bio waste selected from the group consisting of palm oil mill effluent, soapstock, and combinations thereof; introducing the bio waste effluent stream into a fluidized catalytic cracking unit; contacting the bio waste with a catalyst in the fluidized catalytic cacking unit; and cracking at least a portion of the bio waste stream to form cracked products that comprise a cracked product stream.

Upgrading bio-waste in FCC

The present disclosure provides methods and systems for co-processing a hydrocarbon feed in an FCC system with a second feed of a biomass-derived pyrolysis oil and a third feed of a plastic-derived pyrolysis oil and/or lubricant. A method of co-processing fluid catalytic cracking feeds, includes: introducing a hydrocarbon feed to a fluid catalytic cracking reactor, wherein the hydrocarbon feed comprises hydrocarbons; introducing a biomass feed to the fluid catalytic cracking reactor wherein the biomass feed comprises a biomass-derived pyrolysis oil; introducing a waste feed to the fluid catalytic cracking reactor, wherein the waste feed comprises a plastic, a plastic-derived pyrolysis oil, a lubricant, or a combination thereof; and reacting at least the hydrocarbon feed, the biomass feed, and the waste feed in the presence of one or more fluid catalytic cracking catalysts in the fluid catalytic cracking reactor to produce cracked products.

Co-processing of pyrolysis oils, lubricants, and/or plastics

Systems and methods are provided for processing a bio-derived feedstock in a commercial scale reactor to form renewable distillate boiling range fractions while managing the heat release. The management of the heat release is achieved in part by introducing 1.0 vol % or more of CO into at least a portion of the reaction environment for hydroprocessing of the bio-derived feedstock. The 1.0 vol % or more of CO can selectively reduce the activity of hydrotreating catalyst for olefin saturation.

Renewable diesel production with heat release management

This application relates to production of renewable fuels, including a method of producing renewable fuels. The method comprises hydrotreating a biofeedstock by contacting reactants comprising a combined feedstock and hydrogen with a hydrotreating catalyst to produce normal paraffins. The combined feedstock comprises a biofeedstock and an additional feedstock. The biofeedstock has about 10% or more of each of metals, phosphorous, and chlorophyll than the additional feedstock. The biofeedstock comprises the metals in an amount of about 300 parts per million ('ppm') or less, the phosphorous in an amount of about 300 ppm or less, and the chlorophyll in an amount of about 50 ppm or less. The method further comprises isomerizing at least a portion of the normal paraffins to produce branched paraffins in an isomerization effluent.

Systems and methods for renewable fuels

A method may include: hydropyrolyzing a bio feedstock in a hydropyrolysis unit to produce at least a hydropyrolysis oil; introducing at least a portion of the hydropyrolysis oil with a hydrocarbon co-feed into a fluidized catalytic cracking unit; and cracking the hydropyrolysis oil in the fluidized catalytic cracking unit to produce at least fuel range hydrocarbons.

System and methods for renewable fuels

Systems and methods are provided for co-processing of biomass oil with mineral coker feeds in a coking environment. The coking can correspond to any convenient type of coking, such as delayed coking or fluidized coking. The biomass oil can correspond to biomass oil with a molar ratio of oxygen to carbon of 0.24 or less on a dry basis. Such types of biomass oil can be formed from pyrolysis methods such as hydrothermal pyrolysis, and are in contrast to biomass oils formed from pyrolysis methods such as fast pyrolysis. By using a biomass oil with a molar ratio of oxygen to carbon of 0.24 or less, improved yields of light coker gas oil can be achieved in conjunction with a reduction in the yield of heavy coker gas oil.

Co-processing of biomass oil in coker

Methods of refining a whole crude oil stream. The methods involve first processing the crude either through a hydrotreating reactor comprising a dewaxing reactor bed or a flash evaporation separator. The treated streams are then further processed through a demetalization reactor bed, a hydroprocessing reactor bed, or both. The stream can then be still further processed via additional hydrotreating, distillation, or both.
