Problems solved by technology

However, most of these processes are based on coal-based syngas to prepare mixed alcohols, and there are relatively few studies on biomass-based syngas-based mixed alcohols, and the existing biomass indirect liquefaction processes generally have high energy consumption and low raw material utilization. Therefore, it is extremely necessary to further improve this technology, and at the same time be able to comprehensively develop and utilize biomass resources as much as possible

Embodiment

[0037] Such as figure 1 As shown, the comprehensive utilization process of biomass resources provided by this embodiment specifically includes the following steps.

[0038] (1) The raw materials of biomass resources (corn stalk shaped particles) are gasified in a fixed-bed gasifier, and the raw materials are pyrolyzed to produce crude synthesis gas;

[0039] In the process of preparing crude synthesis gas, the pyrolysis temperature of the gasifier: 470°C.

[0040] The measurement results show that the calorific value of the generated biomass synthesis gas is 15MJ / m 3 Above, after being converted into biomass synthesis gas, its energy conversion efficiency is about 75%, and the 25% energy lost is mainly contained in the high-temperature flue gas generated during the energy conversion process. Therefore, in order to reduce energy loss, the generated energy can be reduced The recovered high-temperature flue gas is used to dry and preheat the raw materials of biomass resources, and the ...

Abstract

The invention belongs to the technical field of energy engineering and particularly relates to a comprehensive utilization technology of biomass resources. The process comprises steps as follows: biomass gasification, purification and dust removal of syngas, syngas reforming, conversion of syngas, decarbonization absorption, preparation of polygol from syngas, separation and refining of polygol and the like. The integration of the technology is higher, and the biomass resources are used more sufficiently: tar separated in the purification and dust removal process of the biomass syngas can be further used as a raw material for refining bio-gasoline and biodiesel, and separated wood vinegar can be used for producing feed, fertilizer and the like. Exhaust gas in biomass syngas is further reclaimed, hydrogen in the exhaust gas is recovered with a pressure swing adsorption separation manner and is reused for the preparation process of polygol from syngas through conversion, and accordingly, the comprehensive recycling value of the technology is further increased, and the production cost is effectively reduced.

Description

Technical field [0001] The invention belongs to the technical field of energy engineering, and specifically relates to a patent application for a comprehensive utilization process of biomass resources. Background technique [0002] With the increasing depletion of fossil energy and the increasingly severe environmental problems, the comprehensive utilization of renewable energy has received more and more attention. Biomass energy is the only renewable energy that can directly generate gas, liquid and solid fuels, and it is also the only renewable energy that can replace refined oil and natural gas. Therefore, the large-scale development of material energy can not only alleviate the problem of energy depletion, but also has good social and economic benefits. [0003] Biomass indirect liquefaction technology (to further synthesize liquid fuels through biomass synthesis gas) is one of the important ways to utilize biomass resources. This technology converts biomass resources into li...
