Abstract
A method and an apparatus for producing a chemical compound from biomass based raw material. The bio-mass based raw material is gasified in a gasification device for forming a gasification gas, the gasification gas is treated in the reactor which includes at least one catalyst layer including Fe-based catalyst for forming a hydrocarbon composition, at least one hydrocarbon fraction including olefins is recovered from the hydrocarbon composition, and a chemical compound is formed from the hydrocarbon fraction. Further, the invention relates to the produced chemical compound.
Claims9
A method for producing a chemical compound from biomass based raw material, the method comprising:
- gasifying the biomass based raw material in a gasification device forming a gasification gas,
- treating the gasification gas in a reactor which has a catalyst layer consisting essentially of a Fe-based catalyst for forming a hydrocarbon composition,
- recovering at least one hydrocarbon fraction comprising olefins from the hydrocarbon composition so that the hydrocarbon fraction comprising:
- C3 and C4+ olefins and paraffines,
- C4 olefins and paraffines, and/or
- C6-C18 α-olefins,
- are separated from the hydrocarbon composition, and
- treating the separated hydrocarbon fraction forming a chemical compound, with a material selected from the group consisting of:
- aromatics, maleic anhydride and/or alkenyl succinic anhydride, and the treatment is carried out such that the hydrocarbon composition or the hydrocarbon fraction comprising C3 and C4+ olefins and paraffines is treated by an aromatization which is performed at normal pressure and in the presence of a zeolite catalyst for forming aromatics, and/or the hydrocarbon fraction comprising C4 olefins and paraffines is partially oxidized forming maleic anhydride.
