Abstract
A system and method for processing unconditioned syngas first removes solids and semi-volatile organic compounds (SVOC), then removes volatile organic compounds (VOC), and then removes at least one sulfur containing compound from the syngas. Additional processing may be performed depending on such factors as the source of syngas being processed, the products, byproducts and intermediate products desired to be formed, captured or recycled and environmental considerations.
Claims27
A method of processing a syngas, the method comprising:
- reacting the first syngas stream, an oxidant, and one or more gaseous hydrocarbons in a reactor to yield a second syngas stream;
- removing carbon dioxide from the second syngas stream to yield a third syngas stream and a carbon dioxide stream;
- and
- recycling at least a portion the carbon dioxide stream for use during generating the first syngas stream.
A method of processing a syngas, the method comprising:
- processing carbonaceous material in the presence of a first carbon dioxide stream to yield a first syngas stream;
- reacting the first syngas stream, an oxidant, and one or more gaseous hydrocarbons to yield a second syngas stream;
- removing carbon dioxide from the second syngas stream to yield a third syngas stream and a second carbon dioxide stream;
- and
- recycling at least a portion of the second carbon dioxide stream for use as at least a portion of the first carbon dioxide stream.
