Abstract
Methods of making syngas, and making chemical products from syngas, are described herein. A reactor is used to convert methane and carbon dioxide to syngas. Carbon dioxide is separated from an effluent of the reactor and recycled to the reactor.
Claims21
A method, comprising:
- converting methane and carbon dioxide to syngas, and converting carbon dioxide to carbon monoxide, in a reactor using a noble metal catalyst;
- separating carbon dioxide from an effluent of the reactor, or a stream derived from the effluent, using a CO2 separator to form a conversion feed;
- and
- recycling at least a portion of the separated carbon dioxide to the reactor.

A method, comprising:
- obtaining syngas from a facility that converts methane and carbon dioxide to syngas, and converts carbon dioxide to carbon monoxide, in a reactor using a noble metal catalyst and recycles carbon dioxide from an effluent of the reactor, or a stream derived from the effluent of the reactor;
- and
- forming one or more chemical products from the syngas.
A method, comprising:
- providing a stream comprising methane, carbon dioxide, and water, hydrogen, or both, to a reactor;
- in the reactor, converting at least a portion of the methane and carbon dioxide to an effluent comprising methane, carbon dioxide, carbon monoxide, water, and hydrogen gas by contacting the methane and carbon dioxide with a noble metal catalyst;
- removing water from the effluent of the reactor, or a stream derived from the effluent, to form a dehydrated effluent;
- separating carbon dioxide from the dehydrated effluent, or a stream derived from the dehydrated effluent, to form a conversion feed and a recycle comprising carbon dioxide;
- routing the recycle to the reactor;
- and
- forming one or more chemical products from the conversion feed.
