Abstract

The invention provides a pyrolysis condensed phase reaction device. The device comprises a cooling box and a reactor arranged in the cooling box, and the cooling box can be filled with cooling liquid; and the reactor comprises a vertically arranged seat body and a cover body covering the seat body in the horizontal direction, a silk screen reaction assembly is installed on the side, facing the cover body, of the seat body, and air holes are formed in the seat body. According to the pyrolysis condensed phase reaction device, a sample is pyrolyzed through the silk screen reaction assembly located in the cover body, volatile components can be rapidly cooled through the cooling liquid filled in the cooling box, then the gas phase retention time can be greatly shortened, and the gas phase secondary reaction is effectively inhibited; and meanwhile, the air holes can be externally connected with an air pressure adjusting device to adjust the pressure in the cover body, so that the evaporation rate of a liquid intermediate product is changed, the secondary reaction of the condensed phase is controlled, a gaseous product can be guided out by utilizing the air holes after the reaction is completed, and subsequent analysis and research are facilitated.

Description

technical field [0001] The invention relates to the technical field of chemical reaction devices, in particular to a pyrolysis condensed phase reaction device. Background technique [0002] Pyrolysis reaction refers to the chemical decomposition process in which organic matter is heated to a certain extent in the absence of oxygen or oxygen to make it into gaseous, liquid or solid products. In the methods of studying various organic pyrolysis mechanisms, traditional experimental equipment (such as tube furnace reactor, settling furnace reactor, thermogravimetric analyzer or reactor, etc.) can meet most of the experimental needs, but these experimental equipment All have a common shortcoming, that is, the secondary reaction in the reaction process cannot be avoided. Due to the existence of the secondary reaction, the finally collected gas, liquid, and solid three-state products are quite different from the initial products. , restricting the study of the pyrolysis reaction m...
