PROCESS FOR PREPARING A SUSPENSION OF SOLID BIOMASS PARTICLES IN A HYDROCARBON-CONTAINING LIQUID AND CONVERTING THE SUSPENSION

摘要

A catalytic cracking process comprising a) preparing a suspension of solid biomass particles in a hydrocarbon-containing liquid, comprising a first particle size reduction step wherein the particle size of a solid biomass material is reduced to produce a first particulate product comprising solid biomass particles; a mixing step, wherein the first particulate product is suspended in a hydrocarbon-containing liquid to produce a suspended first particulate product comprising solid biomass particles suspended in the hydrocarbon-containing liquid;and a second particle size reduction step, wherein the particle size of the suspended first particulate product is further reduced to produce a suspended second particulate product comprising solid biomass particles suspended in the hydrocarbon-containing liquid; and b) contacting the suspension produced in step a)with a catalytic cracking catalyst at a temperature of more than 400°C in a catalytic cracking reactor to produce one or more cracked products.
