摘要:
A method for generation of power and Fischer-Tropsch synthesis products by producing synthesis gas comprising hydrogen and carbon monoxide, producing Fischer-Tropsch synthesis products and Fischer-Tropsch tailgas from a first portion of the synthesis gas, and generating power from a second portion of the synthesis gas, from at least a portion of the Fischer-Tropsch tailgas, or from both. The method may also comprise conditioning at least a portion of the synthesis gas and/or upgrading at least a portion of the Fischer-Tropsch synthesis products. A system for carrying out the method is also provided.
摘要:
A method of gasification by introducing a feed material to be subjected to gasification into a dual fluidized bed gasifier comprising a pyrolyzer fluidly connected with a combustor such that a circulation stream comprising a heat transfer material can be continuously circulated between the pyrolyzer, in which the temperature of the circulation stream is reduced, and the combustor, in which the temperature of the circulation stream is increased, wherein the pyrolyzer is operable to convert at least a portion of the feed material into a gasifier product gas comprising hydrogen and carbon monoxide, and wherein the combustor is operable to increase the temperature of the circulation stream via combustion of char introduced thereto with the circulation stream and at least one supplemental fuel. A system for carrying out the method is also provided.
摘要:
A thermal conversion process comprising: pyrolizing or gasifying a carbonaceous feedstock to produce a first synthesis gas having a first H2:CO ratio of less than a minimum value or greater than a maximum value; providing enriched oxygen; and subjecting the first synthesis gas to partial oxidation in the presence of at least a portion of the enriched oxygen to produce a conditioned synthesis gas having a desired ratio of H2:CO in the range of from the minimum value to the maximum value. A method of producing FT product liquids by providing a conditioned synthesis gas according to the process and producing FT product liquids by subjecting the conditioned synthesis gas to FT reaction under FT operating conditions. A system for carrying out the methods is also provided.
