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.

A method for producing a chemical compound from biomass based raw material, characterized in that
- the biomass based raw material is gasified in a gasification device for forming a gasification gas,
- the gasification gas is treated in the reactor which comprises at least one catalyst layer including Fe-based catalyst for forming a hydrocarbon composition,
- at least one hydrocarbon fraction comprising olefins is recovered from the hydrocarbon composition so that the hydrocarbon fraction comprising C3 and C4+ olefins and paraffines, the hydrocarbon fraction comprising C4 olefins and paraffines and/or the hydrocarbon fraction comprising C6-C18 α-olefins are separated from the hydrocarbon composition, and
- the separated hydrocarbon fraction is treated for forming a chemical compound.
An apparatus for producing a chemical compound from biomass based raw material, characterized in that the apparatus comprises
- a gasification device (2) in which the biomass based raw material (1) is gasified to form a gasification gas (3),
- a feeding device for feeding the biomass based raw material (1) to a gasification device (2),
- a reactor (4) comprising at least one catalyst layer in which the gasification gas (3) is treated by means of Fe-based catalyst for forming a hydrocarbon composition (5),
- a recovery device (6) for recovering at least one hydrocarbon fraction (7,7a,7b,7c) comprising olefins so that the hydrocarbon fraction comprising C3 and C4+ olefins and paraffines, the hydrocarbon fraction comprising C4 olefins and paraffines and/or the hydrocarbon fraction comprising C6-C18 α-olefins are separated from the hydrocarbon composition, and
- at least one treatment device (8,10,12,16,18) for forming a chemical compound (9,11,17,19) from the separated hydrocarbon fraction.
