Abstract

PURPOSE: To obtain olefins in high yeilds and to recycle and reuse heating medium particles of calcium sulfate under complete treating conditions of heavy oils in the thermal cracking process.
CONSTITUTION: Raw materials comprising heavy oils and/or finely pulverized coal are fed to a reactor wherein heating medium particles containing calcium sulfate heated at 700W900°C, and converted to gases and coke. The calcium sulfate is converted to calcium sulfide, and the heating medium particles having deposited carbon are transferred to a regenerator, where the coke is burned in the presence of an excess of O2 at 750W1200°C to convert calcium sulfide to calcium sulfate. The calcium sulfate is recycled to the reactor. H2,CO, and methane in the produced gas react with CaSO4 as shown in the reaction formulas to consume H2, thus suppressing the hydrogenation of olefins.
