Abstract

A device for pyrolysing biomass comprises: a reactor space; a first feed for biomass material connecting to the upper zone thereof; a second feed for heated heat carrier material connecting to the upper side of the reactor space; a first discharge for pyrolysis gas connecting to the upper zone of the reactor space at a distance from the first feed; and a second discharge for solid material, for instance carbon and heat carrier material, connecting to the underside of the reactor space. A substantial separation between the discharge flows of pyrolysis gas and solid material takes place predominantly under the influence of gravitational force, without interposing of a cyclone. The reactor space is modelled such that the direct flow from the first feed and the second feed to the first discharge is blocked. A mechanical mixer is present in the reactor space for the purpose of mixing the flow of biomass material with the flow of preheated heat carrier material.

Description

technical field [0001] The present invention relates to a device for pyrolyzing biomass comprising: [0002] A reactor having a shell and a reaction space disposed in the shell; [0003] A first feed pipe for biomass material or other organic material connected to the upper region of the reaction space; [0004] a second feed pipe for heated heat-carrying material, such as sand, connected to the upper part of the reaction space; [0005] a first outlet for pyrolysis gas connected to the upper region of the reaction space at a distance from the first feed pipe; and [0006] A second outlet for solid materials such as carbon and heat transfer material is connected to the lower part of the reaction space. Background technique [0007] Such reactors are known in numerous examples from WO-A-03 / 106590, WO-A-2007 / 017005 and DE-A-197 38 106, among other documents. [0008] Pyrolysis gases have been produced in the mixer region in the reaction space. These gases entrain fine car...
