Abstract
The present disclosure relates generally to integrated processes for the production, storage, and use of methanol. In one aspect, the present disclosure provides a process for producing a H2/CO stream, the process comprising for a first period of time, synthesizing methanol by hydrogenation of CO2, and decomposing a second feed stream including the methanol to form CO and H2; and for a second period of time, decomposing a third feed stream comprising stored methanol to form CO and H2. A synthesized methanol fraction of the second feed stream is substantially greater than a synthesized methanol fraction of the third feed stream.
Claims20
A process for the production of a H2/CO stream comprising hydrogen and carbon monoxide, the process comprising:
- for a first period of time,
- providing a first feed stream comprising hydrogen and CO2;
- contacting the first feed stream with a hydrogenation catalyst to form a first product stream comprising synthesized methanol;
- providing a second feed stream comprising at least a portion of the synthesized methanol of the first product stream;
- contacting the second feed stream with a methanol decomposition catalyst to decompose at least a portion of the methanol to form a second product stream comprising CO and H2;
- and
- providing at least a portion of the CO and the H2 of the second product stream to the H2/CO stream;
- and
- for a second period of time,
- providing a source of stored methanol;
- providing a third feed stream comprising stored methanol;
- contacting the third feed stream with the methanol decomposition catalyst to decompose at least a portion of the methanol to form a third product stream comprising CO and H2;
- and
- providing at least a portion of the CO and the H2 of the third product stream to the H2/CO stream,
- wherein the synthesized methanol fraction of the second feed stream is greater than the synthesized methanol fraction of the third feed stream.
