The present disclosure relates generally to novel biomass pyrolysis processes and systems that decrease entrainment of char and other contaminants with the pyrolysis vapors as a direct consequence of the biomass feedstock comprising particles that are larger than a defined minimum diameter. The biomass feedstock may optionally be compressed to form feedstock pellets that are larger than a defined minimum diameter.

Increasing stability of a pyrolysis product

Integrating a biomass pyrolysis and upgrading process into a fluid catalytic cracking unit. The process uses conventional FCC feed and a mixture of a solvent and biomass to produce upgraded fuel products. A slurry stream composed of solid biomass particles and a solvent is fed into an FCC riser through a slurry pump to achieve biomass pyrolysis and in situ pyrolysis oil upgrading. The catalytic cracking of the conventional petroleum feed also occurs in the riser.

Integrated FCC biomass pyrolysis/upgrading

A process for quenching, separating and collecting targeted components of a hot pyrolysis product stream from the pyrolysis of biomass is provided. The process utilizes sequential steps of rapid quenching and electrostatic precipitation comprising injecting a coolant comprising at least one of nitrogen, a noble gas and mixtures thereof into a hot pyrolysis vapor to selectively condense a first fraction of components from the hot pyrolysis vapor at a first predetermined temperature which is then collected by electrostatic precipitation in a first electrostatic precipitator at about the first predetermined temperature, where a wall temperature of the first electrostatic precipitator is maintained slightly higher than the first predetermined temperature. The sequential steps of coolant injection and collection are repeated at progressively cooler temperatures in order to selectively collect one or more fractions of the hot mixture.

Selective temperature quench and electrostatic recovery of bio-oil fractions

A biomass pyrolysis product is quenched by direct cooling with a cold quench fluid and initial product separation is performed based on boiling point and solubility in the quench fluid. A properly chosen quench fluid may act as a selective solvent, thus providing dilution of unstable precursors of pyrolytic lignin or other heavy by-products, and/or separation of certain undesirable pyrolysis oil components such as water and light acids.

Absorption and quench method for biomass pyrolysis product

A process for converting biomass to hydrocarbons and oxygenates that may include providing a biomass feedstock and de-oxygenating the biomass feedstock to form a solid-intermediate. The process may further include liquefaction of the solid intermediate, which may be carried out either by rapid heating followed by condensation or by liquefying by applying high pressure. The liquefaction of the solid intermediate may produce a mixture of hydrocarbons and oxygenates, which is generally termed as biocrude. Further, the biocrude is processed by one or more refining means for production of hydrocarbons that can be used as fuel.

Process for converting biomass to hydrocarbons and oxygenates

This invention relates to biomass pyrolysis through the use of a hot liquid refinery feedstock as a heat transfer medium, preferably a vacuum gas oil feedstock.

Biomass pyrolysis in refinery feedstock

The present invention relates generally to a method for removing contaminants from a fluid stream and chemically upgrading the stream at the same time. More particularly, the invention relates to a catalytic moving bed filter for removing contaminants from a gas or vapor stream and to compositions comprising both moving bed filter materials and one or more catalysts intimately admixed therewith.

Catalytic moving bed filter

Described is a process for converting pyrolysis oil obtained by pyrolysis of biomass into fuel range hydrocarbon by alcoholysis of pyrolysis oil with subsequent hydrotreatment. A straightforward methodology to prepare upgradeable pyrolysis oil via alcoholysis. A method hydrotreating technology for oxygen removal and hydrocarbon production. The resulting hydrocarbon products are 100% fungible with conventional transportation fuels.
