ABSTRACT：<br/>It was postulated that a blend of Canadian oilsands bitumen and Fischer-Tropsch wax would perform better under catalytic cracking conditions than either feed material on its own, due to their opposite, but complementary cracking nature. The co-processing of bitumen and wax in a 90:10 mass ratio over an amorphous silica-alumina acid catalyst. The reactions were performed in batch reactors under differentreaction temperatures from 340 to 400 °C for a constant reaction period of 2 hours. The product viscosity from catalytic cracking of the bitumen-wax mixture was consistently lower than that from catalytic cracking of bitumen on its own. The viscosity decreased with increasing reaction temperature. The coke yield on a bitumen basis was slightly lower for the catalytic cracking of the bitumen-wax mixture than for catalytic cracking of bitumen on its own. In the blank test run, the product viscosity from thermal cracking (no catalyst) of the bitumen-wax mixture was higher than that from thermal cracking of bitumen at 400 °C. The dominant factor in the co-processing of bitumen and wax seems to be the extent of wax cracking.
