Embodiment Construction

[0043] definition

[0044] As used herein, the term "about" refers to a + / - 10% variation from the nominal value. It should be understood that such variations are always included in the given values ​​provided herein, whether specifically recited or not.

[0045] The term "hydrocarbon material" as used herein includes hydrocarbons such as methane and other hydrocarbon-containing materials obtained by pyrolysis of fuels (which are commonly referred to as tars, or organic tars, or biotars).

[0046]The term "char" as used herein includes solid material remaining after light gases and tars have been driven off, or from carbonaceous Released solid material.

[0047] Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs.

[0048] In one aspect of the invention there is provided a continuous multi-stage vertical sequential gasification process for th...

Abstract

A continuous multi-stage vertically sequenced gasification process for conversion of solid carbonaceous fuel material into clean (low tar) syngas. The process involves forming a pyrolysis residue bedhaving a uniform depth and width to pass raw syngas there through for an endothermic reaction, while controlling the reduction zone pressure drop, resident time and syngas flow space velocity during the endothermic reaction to form substantially tar free syngas, to reduce carbon content in the pyrolysis residue, and to reduce the temperature of raw syngas as compared to the temperature of the partial oxidation zone.

Description

field of invention [0001] The present invention relates to the field of gasification of carbonaceous feedstocks / fuels and in particular to methods for the conversion of carbonaceous fuel materials into clean high quality syngas substantially free of tar and for the production of clean ash substantially free of carbon and system. Background technique [0002] Gasification can convert carbonaceous materials into useful chemical products. These chemical products typically include synthesis gas (syngas), which can be further combusted to generate electricity, or chemically reacted to produce oxygenates or hydrocarbons in a catalytic system. [0003] Several types of gasification and pyrolysis methods and devices have been developed to achieve efficient conversion of biomass to clean gaseous products. Many gasification processes known in the art have failed due to insufficient attention to low tar production, efficient tar destructions, and complete decarburization of char and ...
