摘要： A process for producing syngas and olefins includes the steps of feeding a catalytic partial oxidation (CPO) reactant mixture having oxygen, first hydrocarbons, and optionally steam to a CPO reaction zone having a CPO catalyst such that at least a portion of the CPO reactant mixture reacts, via an exothermic CPO reaction, to produce syngas having hydrogen (H2), carbon monoxide (CO), carbon dioxide (CO2), water, and unreacted first hydrocarbons. The syngas is characterized by a molar ratio M defined as (H2−CO2)/(CO+CO2). The method further includes feeding a cracking zone feed having second hydrocarbons to a cracking zone such that at least a portion of the second hydrocarbons undergoes an endothermic cracking reaction to produce a cracking zone product stream having olefins, hydrogen, and unreacted second hydrocarbons; and cooling the CPO reaction zone by heating the cracking zone while cooling the CPO reaction zone via heat transfer between the CPO reaction zone and the cracking zone.

摘要： A process for producing methanol including the following steps: (a) reacting, via a catalytic partial oxidation (CPO) reaction, a CPO reactant mixture (hydrocarbons, oxygen, and optionally steam) in a CPO reactor to produce syngas; wherein the CPO reactor has a CPO catalyst; and wherein the syngas includes hydrogen, carbon monoxide, carbon dioxide, water, and unreacted hydrocarbons; (b) introducing the syngas to a methanol reactor to produce a methanol reactor effluent stream; wherein the methanol reactor effluent stream includes methanol, water, hydrogen, carbon monoxide, carbon dioxide, and hydrocarbons; and (c) separating the methanol reactor effluent stream into a crude methanol stream and a vapor stream. The crude methanol stream comprises includes methanol and water. The vapor stream includes hydrogen, carbon monoxide, carbon dioxide, and hydrocarbons; and wherein the crude methanol stream has water in an amount of less than about 10 wt. %, based on the total weight of the crude methanol stream.
