CONTROLLED ACTIVITY PYROLYSIS CATALYSTS

摘要

A catalyst system is disclosed for catalytic pyrolysis of a solid biomass material. The system comprises an oxide, silicate or carbonate of a metal or a metalloid. The specific combined meso and macro surface area of the system is in the range of from 1 m2/g Io 100 m2/g. When used in a catalytic process the system provides a high oil yield and a low coke yield. The liquid has a relatively low oxygen content.
