Abstract
A method and system for reforming a carbonaceous feedstock comprising the steps, reforming the feedstock produce a first synthesis gas, subjecting a portion of the first synthesis gas to catalytic conversion, separating from the synthesis gas conversion product at least one byproduct, and utilizing at least a portion of the at least one byproduct during reforming of additional carbonaceous material. In certain instances, the method and system may be used to produce a liquid fuel.
Claims4
A method of producing liquid hydrocarbons, the method comprising:
- reforming a carbonaceous feedstock that is solid, liquid, or both to produce a first synthesis gas comprising hydrogen and carbon monoxide;
- subjecting at least a portion of the first synthesis gas to Fischer-Tropsch conversion whereby at least a portion of the hydrogen and carbon monoxide in the first synthesis gas is catalytically converted into product comprising liquid hydrocarbons;
- separating from the product a Fischer-Tropsch tailgas comprising at least one component selected from carbon monoxide, hydrogen, methane and carbon dioxide;
- and
- homogeneously combusting at least a portion of the Fischer-Tropsch tailgas to provide at least a portion of the heat for the reforming of additional carbonaceous feedstock.
A method of producing liquid hydrocarbons, the method comprising:
- reforming a carbonaceous feedstock to produce a first synthesis gas comprising hydrogen and carbon monoxide;
- subjecting at least a portion of the first synthesis gas to Fischer-Tropsch conversion whereby at least a portion of the hydrogen and carbon monoxide in the first synthesis gas is catalytically converted into product comprising liquid hydrocarbons;
- removing from the Fischer-Tropsch conversion reactor a catalyst wax mixture comprising Fischer-Tropsch liquid hydrocarbons and catalyst removed from the reactor;
- and
- combining at least a portion of the catalyst wax mixture with at least one carbonaceous material and superheated steam;
- and
- reforming the combined material to produce additional synthesis gas.
