Abstract
The present invention provides for a monolith reactor process for the production of syngas from hydrocarbon and oxygen feeds. The syngas is cooled and separated to produce carbon monoxide and hydrogen, and the purification equipment utilized in this separation process recycles tail gas and fuel gas to the syngas feed gas line and recycles methane from the carbon monoxide separation system for feed back to the monolith reactor. This process results in almost complete carbon to carbon monoxide conversion and very high carbon monoxide and hydrogen recoveries.
Claims25
An improved process for producing carbon monoxide from a monolith reactor comprising the steps:
- a) feeding a feed gas comprising carbon monoxide, carbon dioxide, methane and hydrogen to a carbon dioxide separation system having at least one compressor;
- b) feeding said feed gas from said carbon dioxide separation system to a carbon monoxide separation system;
- c) feeding a hydrogen stream from said carbon monoxide separation system to a hydrogen separation system;
- d) the improvement comprising recycling tail gas from said hydrogen separation system and fuel gas from said carbon monoxide separation system to said compressor in said carbon dioxide separation system.
