A high-throughput reactor for catalytic pyrolysis of biomass

Abstract

A high-throughput reactor suitable for catalytic pyrolysis of biomass, including a preheating tank, a solid powder biomass feeder, a parallel fluidized bed reactor, a multi-channel gas distributor, a multi-channel heating furnace, and a temperature control system , high-resolution flight mass spectrometry; the gas source is connected to the preheating tank, and the preheating tank is connected to the multi-channel heating furnace through a multi-channel gas distributor; the parallel fluidized bed reactor is installed in the multi-channel heating furnace; the temperature control system is connected to the multi-channel heating furnace respectively. The channel heating furnace is connected with the high-resolution flight mass spectrometer; the solid powder biomass feeder is connected with the parallel fluidized bed reactor. The invention has the advantages that a high-throughput catalytic pyrolysis reaction system is composed of a multi-channel heating furnace, a multi-channel gas distributor, and a plurality of fluidized bed reactors, and all reactors are uniformly controlled in temperature. The high-throughput reaction system enables rapid switching. A porous filter bowl is used to separate catalyst, dust and product gases. The product is directly connected to the high-resolution flight mass spectrometer for rapid online analysis.

Description

technical field [0001] The invention relates to the field of biomass catalytic thermal cracking, in particular to a high-throughput reactor suitable for biomass catalytic thermal cracking. Background technique [0002] As a non-renewable fossil resource, with the increase of its consumption, the reserves of fossil resources will decrease, and in the process of developing fossil resources, it will have an impact on the environment. Therefore, it is imperative to find and develop new energy sources, and the development and utilization of green and environmentally friendly renewable biomass resources is one of the excellent options. Biomass resources are renewable resources produced by plants to absorb carbon dioxide by using light energy. my country has abundant biomass energy reserves. The reserves of agricultural waste, energy forestry and other forms of energy crops alone are equivalent to 900 million tons of standard coal. , and the reserves of potatoes, sorghum, sugarcane...

Problems solved by technology

[0004] The high-throughput reactor developed by Symyx and Avantium Company has inspired the design of the present invention, but the above-mentioned two companies have not designed a high-throughput reaction unit with rapid temperature rise and solid feed, due to the catalytic pyrolysis of biomass The reaction requires rapid heating of biomass and intermittent addition of biomass solid powder, so the existing high-throughput reactor cannot meet the needs of biomass catalytic pyrolysis, so a multi-channel fluidized bed reactor is designed in this paper, which can Realize the rapid temperature rise of biomass raw materials, and design a solid powder biomass feeder with solid powder intermittently added, so as to meet the needs of biomass catalytic pyrolysis reaction
