Catalytic cracking experiments on co-processing of methanol and heavy oil at different ratios in a fixed fluidized bed reactor had been conducted. Test results have revealed that when 12.5% of methanol was blended to the heavy oil a good products distribution and relatively higher yield of low-carbon olefins could be obtained. The overall yield of low-carbon olefins could reach 50.16%, with the yield of ethylene, propylene and butylene equating to 5.47 %, 28.93% and 15.76 %, respectively.展开更多
