Abstract
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.
Claims9
A method of upgrading biomass to fuel products comprising:
- a) mixing a biomass feed stream with a solvent to produce a mixed feed stream,
- b) transporting the mixed feed stream through a slurry pump, mixer, or mixer and slurry pump to a riser,
- c) combining the mixed feed stream (a) with a conventional FCC feed stream and regenerated catalyst in the riser,
- wherein the mixed feed stream is injected at one or more injection points along the riser that are distinct from the injection point of the conventional FCC feed stream,
- d) cracking and upgrading the mixed feed stream and the conventional FCC feed stream to upgraded fuel products in the riser,
- e) separating the upgraded fuel products from deactivated catalyst in reactor/stripper,
- f) regenerating the deactivated catalyst in regenerator, and
- recycling the regenerated catalyst to the riser (c).
