Kind Code:
A
Abstract:
In the treatment of petroleum heavy oil by thermally cracking a petroleum heavy oil mixed with an alkali metal carbonate or carbonates at a cracking temperature of 450 DEG to 650 DEG C and recovering the resulting low sulfur liquid hydrocarbon and light hydrocarbon gas, (1) gasification of residual coke produced by said cracking, in the presence of the alkali metal carbonate or carbonates and an alkali metal sulfide or sulfides by-produced during the cracking, with steam alone or steam together with an oxygen-containing gas, at 550 DEG to 800 DEG C and under the atmospheric pressure to 10 atm. to produce a hydrogen- and CO2- rich gas, and (2) regeneration from said by-produced alkali metal sulfide or sulfides to said alkali metal carbonate or carbonates, with CO2 gas produced by said gasification and steam, are simultaneously carried out in the same reaction zone.
