Abstract
A system for using carbonaceous material includes a steam reformer, a hydrocarbon reformer, and at least one gas-cleanup system. Also described are methods of producing liquid fuel and/or chemicals from carbonaceous material.
Claims30
A system for using carbonaceous material, the system comprising:
- a steam reformer connected to a first source of recycled conditioned syngas for combusting therein to provide heat and to produce a first reactor product gas, wherein the steam reformer is configured to receive a prepared carbonaceous material or a densified carbonaceous material;
- a hydrocarbon reformer connected to a second source of recycled conditioned syngas and to a stream containing oxygen gas to form a combustion zone and/or a reaction zone of the hydrocarbon reformer, and further configured to receive a portion of the first reactor product gas, the hydrocarbon reformer configured to produce an improved syngas;
- and
- at least one gas clean-up system configured to receive the improved syngas and remove at least one contaminant in the improved syngas to produce a new conditioned syngas, the at least one gas clean-up system comprising a gas clean-up system output through which the new conditioned syngas exits,
- wherein the gas clean-up system output serves as the first source of recycled conditioned syngas connected to the steam reformer and as the second source of recycled conditioned syngas connected to the hydrocarbon reformer.

A method of producing liquid fuel and/or chemicals from carbonaceous material, the method comprising:
- combusting a first portion of conditioned syngas in a steam reformer, thereby causing a prepared carbonaceous material or a densified carbonaceous material to react with a superheated steam to produce a first reactor product gas;
- reacting a second portion of conditioned syngas and a stream containing oxygen gas with at least a portion of the first reactor product gas in a hydrocarbon reformer to produce an improved syngas;
- performing clean-up of the improved syngas to produce new conditioned syngas;
- transferring a first portion of the new conditioned syngas to a synthesis system to produce tail gas and at least one from the group consisting of liquid fuel and chemicals;
- and
- recycling a second portion of the new conditioned syngas for use as the first portion of conditioned syngas and the second portion of conditioned syngas.
