摘要:
Disclosed herein are a gas-to-liquid (GTL) producing method and system for floating production, storage, and offloading (FPSO). The gas-to-liquid (GTL) producing method for FPSO according to the present invention, which is to produce GTL in FPSO, may include: 1) a pre-treating step of pre-treating natural gas produced at an offshore gas field; 2) a reforming step of reacting the pre-treated natural gas in a presence of a catalyst to produce syngas containing hydrogen and carbon monoxide; 3) a synthesis step of supplying the syngas to a Fischer-Tropsch reactor and reacting the syngas to produce liquid hydrocarbon; and 4) an upgrading step of separating the liquid hydrocarbon into gas, naphtha, and syncrude and supplying hydrogen to hydrofinish the liquid hydrocarbon.
摘要:
Disclosed is a method relating to hydrocarbon production by gasification of carbonaceous material, for example, a two-stage gas washing method as a part of gas refining. Disclosed is a method for hydrogen sulfide and carbon dioxide removal from synthesis gas produced by gasification. Disclosed is a use of a combination of two chemical wash approaches. The process can be utilized as a part of biomass to liquid (BTL) process.
摘要:
A process for producing acrylic acid from carbonaceous materials such as biomass. The carbonaceous material, such as biomass, is gasified to produce synthesis gas. The synthesis gas then is subjected to a plurality of reactions to produce acrylic acid.
摘要:
A method of gasifying carbonaceous material is described. The method comprises a first step of pyrolysing and partially gasifying the carbonaceous material to produce volatiles and char. The volatiles and the char are then separated and, subsequently, the char is gasified and the volatiles are reformed. The raw product gas is then finally cleaned with char or char-supported catalysts or other catalysts.
摘要:
A biomass gasification gas purification system includes a dust collector for removing dust in biomass gasification gas (containing tar components) acquired by gasifying biomass by a biomass gasification furnace, a desulfurizer for removing sulfur oxide components in the dust-removed biomass gasification gas, a pre-reforming reactor for reforming tar components in the desulfurized biomass gasification gas, a steam feed unit for feeding steam to an upstream side of the pre-reforming reactor, and a natural-gas feed unit for feeding natural gas on an upstream side of the desulfurizer.

摘要:
A method of producing a hydrocarbon composition, the method including providing a biomass raw-material; gasifying the raw-material in the presence of oxygen to produce a gas containing carbon monoxide, carbon dioxide, hydrogen and hydrocarbons possibly together with inert components; separately increasing the hydrogen-to-carbon monoxide ratio of the gas to a value of about 2; feeding the gas to a Fischer-Tropsch reactor; converting in the Fischer-Tropsch reactor at least a significant part of the carbon monoxide and hydrogen contained in the gas into a hydrocarbon composition containing C4-C90 hydrocarbons; and recovering the hydrocarbon composition. Fresh external hydrogen is introduced into the gas before feeding into the Fischer-Tropsch reactor. By using external hydrogen feed, the capacity of a biomass gasification process can be increased and any need for a Water Gas Shift for producing hydrogen from carbon monoxide and steam can be eliminated.
