Abstract
Synthetic crude petroleum is produced by catalytically cracking a biomass material (P) comprising (a) a plant oil and/or (b) an animal oil and/or (c) a rubber using a catalyst. The catalyst comprises alumina with or without a component (Q) chosen from silica and/or crystalline aluminosilicate zeolites and/or rare earth oxides and/or sodium oxide admixed with alumina. If present, the total amount of said component constitutes a lesser amount by weight of the catalyst mixture.
