Abstract

The invention belongs to the field of rapid pyrolysis of biomass, and specifically discloses a reactor for studying the interactive reaction of three-component pyrolysis of biomass, which includes a gas carrier container, a test tube, a fixed bed furnace, a condensation device and an air bag, wherein: The gas carrier container, test tube, condensing device and air bag are connected in sequence, and the fixed bed furnace is arranged outside the test tube; a slideway and a plurality of spacers engaged with the slideway are arranged in the test tube; the spacer and the slideway The gaskets are provided with through holes and grooves, the through holes are used for the circulation of the carrier gas, and the grooves are used for placing the reactants; the test tube is provided with a limit device, which is used to limit the pad Axial position of the slice in the test tube. The present invention can quickly mix the volatiles produced by different components and have an interactive reaction under the condition of ensuring that the volatiles are taken out of the reactor in time, and effectively inhibit the secondary reaction of biomass pyrolysis. The formation mechanism of the qualitative components is of great significance.

Description

technical field [0001] The invention belongs to the field of rapid pyrolysis of biomass, and more specifically relates to a reactor for studying the interactive reaction of pyrolysis of three components of biomass. Background technique [0002] In recent years, crude oil and petroleum resources have become increasingly scarce, and it is imperative to develop rapid pyrolysis of biomass to produce bio-oil. Unlike the first-generation biomass fuel ethanol, which only uses the sugar content of biomass, the second-generation biomass focuses on the utilization of all components. However, the three components of biomass, especially lignin and hemicellulose, due to their large molecular weight and amorphous structure, and their interactive reactions in pyrolysis, give us an opportunity to understand the various components of pyrolyzed bio-oil, especially heavy Qualitative components have brought great difficulties. At present, a lot of research has been done on the mechanism of ra...

Problems solved by technology

However, the three components of biomass, especially lignin and hemicellulose, due to their large molecular weight and amorphous structure, and their interactive reactions in pyrolysis, give us an opportunity to understand the various components of pyrolyzed bio-oil, especially heavy Qualitative components pose great difficulties

At present, a lot of research has been done on the mechanism of rapid pyrolysis of biomass to produce bio-oil from a single component, but it is far from enough to explore the components of bio-oil from a single component, and it is necessary to study their interaction conduct research

[0003] For rapid pyrolysis of biomass, the main goal is to increase the liquid yield. Due to the closed environment of the existing instrument ampoule, the volatile matter stays in the reactor for too long, so that the secondary reaction to form coke is inherent. Therefore, it is urgent to develop a new type of reactor to effectively inhibit the secondary reaction of biomass pyrolysis, thereby increasing the yield of bio-oil
