Abstract
The invention relates to a process for conversion of a feedstock comprising solid particles into at least a gaseous compound in a reactor comprising a vertically extending swirl chamber comprising a conical upper part with a decreasing diameter in upward direction, at least one tangential inlet at the bottom of the swirl chamber, and an outlet at the upper end of the swirl chamber, wherein the process is selected from pyrolysis, allothermal gasification or carbonisation of a carbon-aceous feedstock. The invention further relates to a process for conversion of a feedstock comprising solid particles into at least one or more gaseous compounds in such reactor.

A process for converting o feedstock comprising solid carbonaceous particles into at least one or more gaseous compounds, the process comprising:
- (a) supplying the feedstock at the bottom end of a vertically extending swirl chamber defined by a wall, a bottom and an upper end, the swirl chamber comprising a conical upper part with a decreasing diameter in upward direction, wherein the wall of the conical upper part of the swirl chamber has a first angle with the vertical;
- at least one tangential inlet at the bottom of the swirl chamber;
- and an outlet at the upper end of the swirl chamber
- (b) supplying an inert gas tangentially to the swirl chamber through the at least one tangential inlet, forming a layer of feedstock particles on the wall of the conical upper part of the swirl chamber,
- (c) converting at least part of the feedstock into at least one of more gaseous compounds in the swirl chamber at elevated temperature, wherein the converting takes place in the layer of feedstock particles, and
- (d) discharging a stream comprising the one or more gaseous compounds via the outlet, wherein the process is selected from pyrolysis, allothermal gasification, torrefaction, or carbonisation of the carbonaceous feedstock
