Abstract

The invention belongs to the technical fields of biomass utilization, energy and chemical industry, and specifically relates to an organic matter conversion process. The conversion process uses at least one of the iron oxide compound, the desulfurization waste agent of the iron oxide compound, or the regeneration of the desulfurization waste agent of the iron oxide compound as a catalyst, and at the same time controls the molar ratio of iron element to sulfur element in the reaction system. In the presence of carbonylation, it can effectively use carbonylation to block the free radical polycondensation of organic matter in the cracking process, and realize the transformation of CO and water into active hydrogen hydrogenation. In this conversion reaction, organic matter, especially biomass solids, can be directly carried out without dehydration. In the conversion reaction, additional water can be added to the biomass liquid or mineral oil. While increasing the liquefaction yield, it can also increase the calorific value of the obtained oil. After the conversion reaction is completed, a large amount of waste water will not be generated.

Description

technical field [0001] The invention belongs to the technical fields of biomass utilization, energy and chemical industry, and specifically relates to an organic matter conversion process. Background technique [0002] With the rapid development of social economy, fossil non-renewable energy sources such as coal, crude oil, natural gas, and oil shale are becoming increasingly exhausted. At the same time, the CO produced by the combustion of such fossil non-renewable energy 2 , SO 2 , NO x Environmental pollution caused by pollutants such as pollutants is also becoming more and more serious, which forces humans to think about ways to obtain energy and methods to improve the environment. [0003] At present, biomass liquefaction technology has become a new means of obtaining energy. This technology is an important part of the utilization of biomass resources. The liquefaction mechanism is as follows: biomass is first cracked into oligomers, and then dehydrated and dehydroxyl...
