VAPOR PHASE CRACKING OF HEAVY GAS OIL

摘要

1. Full vaporization of feed was approached by optimizing nozzle tip position and flow rate of carrier gas. 2. Low coke yield and predominantly higher yield of olefins compared with alkanes are in agreement with pure vapor phase cracking behavior. 3. Coke and gas yields were more sensitive to temperature than residence time in a short operating time range. Residence time became dominant on coke yield as it was increased significantly.
