Abstract
Provided is a method and apparatus for producing a hydrocarbon fraction. The hydrocarbon fraction is formed from biomass based synthesis gas, the synthesis gas is fed through at least two catalyst layer, the first catalyst layer includes Fe-based catalyst, the second catalyst layer includes Co-based catalyst, and the synthesis gas is treated by supplying the synthesis gas through the first and second catalyst layers in order to form a hydrocarbon composition including the hydrocarbon fraction. Further, provided is a hydrocarbon fraction and its use.

A method for producing a hydrocarbon fraction, wherein
- the hydrocarbon fraction is formed from biomass based synthesis gas,
- the synthesis gas is fed through at least two catalyst layers,
- a first catalyst layer includes Fe-based catalyst,
- a second catalyst layer includes Co-based catalyst,
- the synthesis gas is treated by supplying the synthesis gas through the first and second catalyst layers forming a hydrocarbon composition including the hydrocarbon fraction, and
- reaction pressure is between 3 to 10 bar in the first catalyst layer and reaction pressure is between 3 to 10 bar in the second catalyst layer.
An apparatus for producing a hydrocarbon fraction, wherein the apparatus comprises
- a feeding device for feeding biomass based synthesis gas into the apparatus,
- at least one reactor which comprises at least one catalyst layer and in which the synthesis gas is treated,
- at least two catalyst layers through which the synthesis gas is fed, and a first catalyst layer includes Fe-based catalyst and a second catalyst layer includes Co-based catalyst, in order to form a hydrocarbon composition including the hydrocarbon fraction, and
- the apparatus comprises a pressure controlling device to control the pressure in the first catalyst layer and in the second catalyst layer so that reaction pressure is between 3 to 10 bar in the first and second catalyst layers.
A hydrocarbon fraction, wherein the hydrocarbon fraction has been formed from biomass based synthesis gas so that the synthesis gas has been treated in at least two catalyst layers in which a first catalyst layer includes Fe-based catalyst and a second catalyst layer includes Co-based catalyst in order to form a hydrocarbon composition including the hydrocarbon fraction and the hydrocarbon fraction has been separated from the hydrocarbon composition.
