Biomass is converted into a bio-oil containing stream in a riser reactor having multiple ports for the entry of fresh catalyst. Hard coke formed during pyrolysis may be separated from the riser effluent fraction containing which contains spent catalyst, soft coke and char. The separated hard coke may then be fed back into the riser reactor. The riser reactor may further have a cooling media which quenches the rapid heat transfer to the biomass during pyrolysis of the biomass in the mixing zone of the riser.

Catalyst addition to a circulating fluidized bed reactor

Biomass is converted into a bio-oil containing stream in a riser reactor containing a cooling media. The cooling media quenches the rapid heat transfer to the biomass during cracking of the biomass in the mixing zone of the riser. By lowering the temperature to which the mixing zone effluent is exposed, production of carbon monoxide and light gases is decreased during thermolysis of the biomass.

Use of cooling media in biomass conversion process

A process and system for hydroprocessing biopyrolysis oils is provided and includes the rejuvenation of an at least partially flow constricted biopyrolysis oil hydroprocessing reactor(s) by flushing with a flushing agent at reduced temperatures.

Rejuvenation of biopyrolysis oil hydroprocessing reactors

A renewable fuel may be obtained from a bio-oil containing C-Coxygenates. In a first step, the bio-oil is subjected to a condensation reaction in which the oxygenates undergo a carbon-carbon bond forming reaction to produce a stream containing C+ oxygenates. In a second step, the stream is hydrotreated to produce C+ hydrocarbons.

Process of generating a renewable biofuel from a hydrotreated stream of condensed oxygenates

The amount of renewable hydrocarbons produced from biomass may be increased by pyrolyzing the biomass in a biomass conversion unit in the presence of hydrogen sulfide or a sulfiding agent. The formation of deposits of unwanted carbonaceous materials, such as coke, is reduced by the presence of the hydrogen sulfide or sulfiding agent.

Method of thermolyzing biomass in presence of hydrogen sulfide

Liquid bio-fuels and processes for their production are provided. The liquid bio-fuels can have improved stability, less corrosiveness, and/or an improved heating value.

Liquid bio-fuels

A filter media for the removal of undesirable solid components from a fuel feedstock contains biomass and a catalyst used from the thermocatalytic conversion of biomass into bio-oil.

Method of removing undesirable solid components from a renewable or non-renewable feed and apparatus used in same

A process for preparing a renewable biofuel consists of subjecting a bio-oil mixture to deoxygenation in a hydrotreater and then separating hydrocarbon fractions from the deoxygenated product to form the biofuel. The bio-oil mixture contains a bio-oil feedstream and a treated bio-oil feed. The treated bio-oil feed is a stream from which undesirable heavy materials and solid materials have been removed.

Process for producing renewable biofuel from a pyrolyzed biomass containing bio-oil stream

The recovery of solids, and particularly solid particulates used as catalysts in slurry hydroprocessing, from asphaltene containing hydrocarbons is improved by controlling asphaltene precipitation. The formation of agglomerates of the solid particulates, having an increased diameter, results in the presence of precipitated asphaltenes, possibly due to flocculation. Asphaltene precipitation is controlled by varying process parameters or introducing additional diluent or flush streams that change the polarity of an asphaltene containing liquid product recovered from an effluent of a slurry hydroprocessing reaction zone.

Solids management in slurry hydroprocessing

Slurry hydrocracking a heavy hydrocarbon feed produces a HVGO stream and a pitch stream. At least a portion of the pitch stream is subjected to SDA to prepare a DAO stream low in metals. The DAO is blended with at least a portion of the HVGO stream to provide turbine or marine fuel with acceptable properties for combustion in gas turbines or for marine fuel grades.

Process for producing hydrocarbon fuel

One exemplary embodiment can be a process for making a catalyst including an effective amount of iron for catalyzing one or more reactions in a hydrocarbon conversion system. The process can include grinding and coating the particles. The ground particles can have an effective amount of iron, and substantially all the particles may have a maximum dimension no larger than about 130 microns. The coating can have an effective amount of one or more hydrocarbons to provide the catalyst with improved flowability.

Hydrocarbon conversion system, and a process and catalyst composition relating thereto

One exemplary embodiment can be a slurry hydrocracking process. The process can include providing one or more hydrocarbon compounds having an initial boiling point temperature of at least about 340&#xb0; C., and a slurry catalyst to a slurry hydrocracking zone. The slurry catalyst may have about 32-about 50%, by weight, iron; about 3-about 14%, by weight, aluminum; no more than about 10%, by weight, sodium; and about 2-about 10%, by weight, calcium. Typically, all catalytic component percentages are as metal and based on the weight of the dried slurry catalyst.

Slurry hydrocracking process

A process is disclosed for converting heavy hydrocarbon feed into lighter hydrocarbon products. The heavy hydrocarbon feed is slurried with a catalyst comprising molybdenum supported on a base, such as boehmite or pseudo-boehmite alumina. Iron oxide may also be in the base. The base is preferably bauxite. The heavy hydrocarbon slurry is hydrocracked in the presence of the catalyst to produce lighter hydrocarbons.
