PROCESS FOR OPERATING AN INTEGRATED GAS-TO-LIQUIDS FACILITY

摘要

The present technology is directed to processes involving formation of hydrocarbons and oxygenated hydrocarbons through use of oxygen supplied by ion transport membranes. More particularly, the present technology relates in part to a process involving steam reforming and subsequent production of a synthetic product where carbon dioxide and/or hydrogen downstream of the process is reclaimed to generate the synthetic product. The present technology also relates in part to an ethylene formation process involving a viral-templated coupling catalyst in the presence of an ion transport membrane.

主权项

1. A process comprising
steam reforming a first reforming feed to produce a steam reformed product comprising H2 and CO (“the steam reforming step”); optionally subjecting a second reforming feed comprising the steam reformed product to a second reforming step to produce a second reformed product comprising H2 and CO; and contacting the H2 and CO with a synthesis catalyst to produce a synthetic product and a tail gas (“the contacting step”); wherein
the synthetic product comprises one or more compounds selected from C1 to C100 hydrocarbons, C1 to C100 oxygenated hydrocarbons, or a combination thereof;the first reforming feed comprises CH4; andthe first and/or the second reforming feed comprises one or more of
CO2 separated from the steam reformed product and/or the second reformed product,CO2 separated from the tail gas, orCO2 formed from subjecting at least a portion of the tail gas to a water-gas shift (“WGS”) reaction which forms a WGS product comprising CO2 and H2;heat for the steam reforming step is provided by combustion and optionally partial oxidation;the combustion and optional partial oxidation comprises flowing a combustion gas comprising H2 over a permeate surface of an ion transport membrane and flowing an O2-containing gas over a retentate surface of an ion transport membrane to react the combustion gas, produce heat, and produce an exhaust gas comprising H2O (“the combustion step”).
