The invention relates to producing liquid hydro carbonaceous product (1) from solid biomass (2). In the invention solid biomass (2) is gasified in a gasifier (6) to produce raw synthesis gas (3). The raw synthesis gas (3) is conditioned to purify the raw synthesis gas (3) to obtain purified synthesis gas (4), the conditioning comprising lowering the temperature of the raw synthesis gas (3) in a cooler (19) producing saturated steam (51). Then the purified gas (4) is subjected to a Fischer-Tropsch synthesis in a Fischer-Tropsch reactor (5) to produce liquid hydro carbonaceous product (1). In the invention the saturated steam (51) produced by the cooler (19) is further superheated in a superheating boiler (50) for producing superheated steam (52).

The invention relates to a method and apparatus for producing liquid hydro carbonaceous product (1) such as biofuel from solid biomass (2). The method comprises a gasifying step for gasifying solid biomass (2) in a gasifier (6) to produce raw synthesis gas (3), conditioning of the raw synthesis gas (3) to purify the raw synthesis gas (3) to obtain purified synthesis gas (4) having a molar ratio of hydrogen to carbon monoxide between 2.5 to 1 and 0.5 to 1, preferably to between 2.1 to 1 and 1.8 to 1, more preferably about 2 to 1, and subjecting purified synthesis gas (4) to a Fischer-Tropsch synthesis in a Fischer-Tropsch reactor (5) to produce liquid hydro carbonaceous product (1).
摘要:
A metathesis process of the conversion of olefines, in which at least one olefine is brought into contact with a solid catalyst system comprising on a solid silica carrier 0.1-40% by weight of a tungsten compound under reaction conditions such that the catalyst system converts the olefine into olefines having a different molecular weight. In the process a magnesium oxide or titanium oxide containing co-gel prepared by means of a co-gelling system is used as the silica carrier.

The invention relates to the use of biomethanol from the pulp industry in the production of biohydrogen. The preferred biomethanol comprises purified biomethanol derived from black liquor. The invention also relates to a process for the production of biohydrogen from crude biomethanol recovered from black liquor and to a process for producing hydrocarbon biofuel using such biohydrogen as a hydrogen source. The invention further relates to a biofuel production facility for producing fuel from biohydrogen and biohydrocarbon, and to biofuel so produced. The invention makes it possible to produce a biofuel, wherein 100% of the raw material stems from non-fossil sources.

The present invention relates to an integrated process for producing diesel fuel or fuel additive from biological material by producing paraffins by a Fischer-Tropsch reaction on one hand and by a catalytic hydrodeoxygenation of bio oils and fats on the other hand. The two hydrocarbon streams are combined and distilled together. The invention also relates to the use of lignocellulosic material, such as by-products of the wood-processing industry for producing diesel fuel and to a method for narrowing the chain length distribution of Fischer-Tropsch derived diesel fuel. The invention provides a high-quality middle distillate fraction from various biological sources and most preferably from by-products of the wood-processing industry. The invention also relates to equipment for producing fuel form biological material, which comprises a hydrodeoxygenation reactor (3) for hydrocarbons, a cracking/isomerization reactor (11) for FT paraffins and a separation unit (12) for the combined hydrocarbons. Hydrogen is separated from light fractions in a separation unit (9) and reformed in the process. The equipment is advantageously integrated with a pulp and paper mill, which provides biological material and receives waste and energy.
