摘要:
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).

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.
摘要:
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. Two hydrocarbon streams, which both comprises predominately hydrocarbons of a certain chain length are treated separately and finally combined and distilled together. The invention also relates to the use of 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.
摘要:
Treatment of waste water from a biomass-to-liquid process, said process comprising producing synthesis gas from biomass and conversion of said synthesis gas into liquid hydrocarbons by a Fisher-Tropsch process. The waste waters obtained are purified in common with waste waters from another industrial process to which said biomass-to- liquid process is integrated, such as in forestry, power and/or heat generation, waste incineration or a process in a metal-, petrochemical and/or oil refining industry. The biomass-to-liquid. process and said another industrial process may have a common feed water process unit, a common cooling water process unit and a common waste water treatment unit. The waste water treatment process may comprise a biological purification process and said Fischer-Tropsch process may utilize a cobalt catalyst. An integrated factory comprising a biomass-to-liquid plant and another industrial facility in which both plants are connected to a common waste water treatment facilit is also described.
