요약

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.

대표청구항

1. A method to convert biomass into Fischer Tropsch products, comprising: (a) steam reforming biomass in the presence of carbon dioxide to generate unconditioned syngas comprising at least hydrogen, carbon monoxide and ammonia;(b) hydrocarbon reforming the unconditioned syngas with an oxidant source to generate additional hydrogen and carbon monoxide and produce a syngas of improved quality, wherein the oxidant source includes one or more from the group consisting of carbon dioxide, steam, air, and oxygen;(c) after step (b), cooling the syngas of improved quality;(d) after step (c), removing at least a portion of the steam from the syngas of improved quality;(e) after step (d), compressing the syngas of improved quality;(f) after step (e), removing from the syngas of improved quality, one or more volatile organic compounds from the group consisting of benzene, toluene, phenol, styrene, xylene, and cresol;(g) after step (f), removing ammonia from the syngas of improved quality, thereby producing an ammonia-depleted syngas of improved quality;(h) after step (g), removing carbon dioxide from the ammonia-depleted syngas of improved quality, thereby forming an ammonia-and-carbon-dioxide-depleted syngas of improved quality;(i) recycling a first portion of the removed carbon dioxide for use in step (a);(j) after step (i), introducing the ammonia-and-carbon-dioxide-depleted syngas of improved quality to a Fischer-Tropsch (FT) catalytic synthesis process and generating Fischer-Tropsch products including at least a Medium Fraction Fischer-Tropsch Liquid (MFFTL) and wax.
