Embodiment Construction

[0056] The present disclosure relates to a process for converting a carbonaceous feedstock to a plurality of gaseous products comprising at least methane; the process comprising: providing a carbonaceous feedstock, a hydromethanation catalyst, a syngas feedstock stream, and a steam stream to a hydromethanation A reactor to convert said carbonaceous feedstock into various gaseous products in the presence of a hydromethanation catalyst, carbon monoxide, hydrogen and steam. The syngas feedstream is provided by a partial oxidation (POx) reactor that consumes a portion of the sweetened gas output (methane, carbon monoxide, and hydrogen output) from the hydromethanation reaction for syngas and heat generation . The various gas products are then processed to ultimately form a methane product stream, ideally of sufficient purity to achieve "pipeline quality natural gas" requirements.

Abstract

The present invention relates to processes for preparing gaseous products, and in particular methane, via the hydromethanation of carbonaceous feedstocks in the presence of steam, carbon monoxide, hydrogen and a hydromethanation catalyst.

Description

technical field [0001] The present invention relates to a process for the production of gaseous products, particularly methane, by hydromethanation of carbonaceous feedstocks in the presence of water vapour, carbon monoxide, hydrogen and a hydromethanation catalyst. Background technique [0002] The production of value-added gas products from low fuel value carbonaceous feedstocks such as petroleum coke, coal, and biomass has received renewed attention in light of factors such as higher energy prices and environmental concerns. 例如在US3828474、US3998607、US4057512、US4092125、US4094650、US4204843、US4468231、US4500323、US4541841、US4551155、US4558027、US4606105、US4617027、US4609456、US5017282、US5055181、US6187465、US6790430、US6894183、US6955695、US2003 / 0167961A1、US2006 / 0265953A1、 The use of catalytic gasification of such materials to produce methane and other value added gases is described in US2007 / 000177A1 , US2007 / 083072A1 , US2007 / 0277437A1 and GB1599932 . [0003] Generally, by reacting c...
