The effect of zinc on the kinetics of coke gasification was studied by a nonisothermal method. The results indicated that with the increase of zinc content, coke gasification tended to move to the low-temperature zone, it occurred earlier, and the reaction rate increased.

Gasification of coke or coal typically involves licensed processes with different supplementary, reactant feed schemes and varying gasifying reaction conditions. For example, air is fed directly to air-blown gasifiers, while other gasifiers are fed with high-purity (about 99.5%) oxygen from an air separation unit.

Coke oven gas (stream-1) goes to the gasification plant. First, mainly hydrogen is separated from it in a pressure swing adsorption (PSA) unit, which operates at 10 atm, and is sent to the polygeneration system (stream-3). The rest of the gas, which has high methane content, is sent to the gasification reactor.
