Provided is a reaction intensification structure. The structure includes a pyrolysis gasification apparatus, a flow strengthening mechanism and a turbulence mechanism. The pyrolysis gasification apparatus is cylindrical, and is provided with a feed inlet and a discharge outlet at front and rear ends thereof respectively. The flow strengthening mechanism is provided on an outer wall of the pyrolysis gasification apparatus at a position near the front end, and it is communicated with such apparatus and at an angle of 20? to 50? relative to a radial direction of such apparatus. The turbulence mechanism includes multiple turbulence bodies distributed in an array on an inner wall of the pyrolysis gasification apparatus and protrude towards a center of such apparatus. The turbulence bodies are divided into multiple groups distributed along an axial direction of such apparatus. Each group of turbulence bodies are distributed along a circumferential direction of such apparatus.

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.
