Reaction device with heat exchanger and use thereof

Abstract

The invention relates to a reaction device (1) with a first wall (2) that defines an interior (3) in which a stirring mechanism (4) is located. A heat exchanger (5) is at least partly provided on thefirst outer wall (2) surface facing away from the interior (3) and / or on the stirring mechanism (4), wherein the heat exchanger (5) has a grate structure, and at least two layers are provided which have a grate structure. Thus, it is possible to transfer heat in a precise and efficient manner primarily by means of thermal radiation in endothermic processes at different temperature levels, in particular pyrolysis, gassing, and reforming processes, and thereby use the exhaust heat for other processes.

Description

technical field [0001] The invention relates to a reaction device, which has an outer wall defining an inner space, the inner space accommodates a stirring mechanism, and the reaction device also includes a heat exchanger with a grid structure. It is thus possible to transfer heat in a precise and efficient manner mainly by thermal radiation in endothermic processes at different temperature levels, in particular cracking, gasification and reforming, and thereby use waste heat from other processes. Background technique [0002] In both thermal and thermo-chemical conversion of biofuels and similar organic feedstocks, heat is transferred to the material to be treated by means of heat exchangers. [0003] Examples of use are pyrolysis, gasification and reforming reactors for the degradation and conversion of biofuels or plastics. In these processes it is technically difficult to transfer a large amount of heat to the material to be processed as quickly as possible and at the s...

Problems solved by technology

For this reason, it is often not possible to connect multiple heat exchangers in cascade series

[0004] For the heating medium, water as a heat transfer medium is an alternative with a higher heat capacity, but using the same volume of water at temperatures above 100°C is accompanied by a strong pressure increase

This would severely limit or at least complicate the use as a heat transfer medium and thus also affect the overall system safety aspect
