Abstract
A process for producing syngas and olefins including the steps of feeding a catalytic partial oxidation (CPO) reactant mixture (oxygen, first hydrocarbons, steam) to a CPO reactor (CPO catalyst); wherein the CPO reactant mixture reacts, via CPO reaction, in CPO reactor to produce a CPO reactor effluent (H, CO, CO, water, unreacted first hydrocarbons). The process further includes feeding a cracking unit feed (second hydrocarbons) to a cracking unit to produce a cracking unit product (olefins), a hydrogen-rich stream (hydrogen, CH), and a hydrocarbon recovery stream (Chydrocarbons); wherein the first and the second hydrocarbons are the same or different; recovering a hydrogen-enriched stream (hydrogen) and a hydrocarbon-enriched stream (CH) from the hydrogen-rich stream; and contacting the CPO reactor effluent with the hydrogen-enriched stream to yield hydrogen-enriched syngas, and wherein the M ratio ((H—CO)/(CO+CO)) of the hydrogen-enriched syngas is greater than the M ratio of the CPO reactor effluent.
