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 carbonization of a carbonaceous 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.

1. A process for converting a 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 c
1. A process for converting a 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 carrier gas tangentially to the swirl chamber through the at least one tangential inlet, forming a layer of solid carbonaceous feedstock particles on the wall of the conical upper part of the swirl chamber,(c) converting at least part of the solid carbonaceous 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 solid carbonaceous feedstock particles, and(d) discharging a stream comprising the one or more gaseous compounds via the outlet,wherein the process is pyrolysis of the solid carbonaceous particles, andwherein the heat for pyrolysis process is provided by heating the wall of the swirl chamber, by supplying heated feedstock to the swirl chamber, by supplying heated carrier gas to the swirl chamber, or combinations thereof, with the proviso that no particulate heat source in the form of heated catalyst particles or heated inert particles is supplied to the swirl chamber. 2. The process according to claim 1, wherein the swirl chamber further comprises a lower part with an increasing, constant or decreasing diameter in upward direction, wherein the lower part directly passes into the conical upper part, and wherein, in case the lower part has a decreasing diameter in upward direction, the wall of the lower part of the swirl chamber has a second angle with the vertical that is smaller than the first angle. 3. The process according to claim 2, wherein the lower part has a constant diameter. 4. The process according to claim 2, wherein the lower part has a length and the upper part has a length and the ratio of the length of the lower part to the length of the upper part is below 1. 5. The process according to claim 4, wherein the ratio of the length to the largest diameter of the swirl chamber is between 2 to 8. 6. The process according to claim 1, wherein the first angle with the vertical is between 10 to 60 degrees. 7. The process according to claim 1, wherein the swirl chamber further comprises a conical insert contained in the swirl chamber, centrally located at the bottom of the swirl chamber and defining an annual flow path at the bottom of the swirl chamber. 8. The process according to claim 1, wherein the feedstock and the carrier gas are tangentially supplied to the swirl chamber through the at least one tangential inlet. 9. The process according to claim 1, wherein at least 90% of the solid carbonaceous particle have a Sauter mean diameter between 0.5 to 20 mm. 10. The process according to claim 1, wherein the feedstock is paper sludge. 11. The process according to claim 1, further comprising recycling non-condensable gas separated from the stream comprising the one or more gaseous compounds to the swirl chamber as at least part of the carrier gas.
