NOVELTY - Catalytic cracking process comprises: (a) preparing a suspension of solid biomass particles in a hydrocarbon-containing liquid, comprising e.g. (i) a first particle size reduction step, where the particle size of a solid biomass material is reduced to produce a first particulate product comprising solid biomass particles; and (b) contacting the suspension produced in step (a) with a catalytic cracking catalyst at a temperature of more than 400 degrees C in a catalytic cracking reactor to produce one or more cracked products (124).    USE - The catalytic cracking process is useful for preparing a suspension of solid biomass particles in a hydrocarbon-containing liquid, which is useful for preparing a biofuel and/or a biochemical (all claimed), which is useful in automotive engines.    ADVANTAGE - The catalytic cracking process reduces coke formation and risk of formation of hot spots in the catalytic cracking reactor which could lead to the formation of excessive amounts of char and an unwanted product. The process prepares suspension of solid biomass particles in a hydrocarbon-containing liquid with improved stability and minimum processing steps in a simple manner.    DETAILED DESCRIPTION - Catalytic cracking process comprises: (a) preparing a suspension of solid biomass particles in a hydrocarbon-containing liquid, comprising (i) a first particle size reduction step, where the particle size of a solid biomass material is reduced to produce a first particulate product comprising solid biomass particles, (ii) a mixing step, where 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 (iii) a second particle size reduction step, where 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 degrees C in a catalytic cracking reactor to produce one or more cracked products (124). An INDEPENDENT CLAIM is included for the suspension of solid biomass particles in a hydrocarbon-containing liquid, obtained by the process.
