Problems solved by technology

Commonly used catalysts are mainly natural ores, alkali metals, nickel-based, composite catalysts, etc., but these catalysts are prone to carbon deposition, sintering, and even deactivation when participating in the biomass gasification process, which also makes the catalysts of this type Applications are limited
Therefore, it is necessary to provide a new biomass gasification technology to solve the problems of low calorific value and high tar content of biomass gasification gas in the existing biomass gasification power generation process

Abstract

The invention relates to the technical field of biomass recycling, in particular to a Brown gas catalytic biomass decoupling gasification power generation system which is characterized in that the output end of a feeding device is communicated with a Brown gas catalytic biomass decoupling gasification furnace, and a Brown gas supply system is connected with the Brown gas catalytic biomass decoupling gasification furnace through a pipeline; the Stirling power generation system is provided with a combustor, the Stirling power generation system is connected with the Brown gas catalytic biomass decoupling gasifier through a pipeline, and the tail gas treatment system is connected with the Stirling power generation system through a pipeline. According to the system, biomass decoupling gasification can be achieved through Brown gas step-by-step catalysis, the reaction conditions of a reduction zone are reduced, the air equivalence ratio is reduced, the gas heat value is increased, and the CO2 content is reduced; the Brown gas serving as a catalyst is small in mixing proportion and low in cost; the Brown gas catalysis biomass decoupling gasification gas is upgraded; and the reliability of the formed power generation system is improved.

Description

technical field [0001] The invention relates to the technical field of biomass reuse, in particular to a power generation system of Brownian gas catalyzed biomass decoupling gasification. Background technique [0002] Biomass energy is the only carbon-based renewable energy and one of the effective ways to replace traditional fossil energy. Biomass energy has the advantages of carbon neutrality, renewable, low pollution, wide distribution and large quantity. Therefore, under the policy background of vigorously developing clean energy, biomass gasification power generation technology has made great progress, but its equipment technology is still There are many problems. [0003] Biomass gasification is one of the effective means of biomass thermochemical conversion and utilization. However, its gasification combustible gas has a low calorific value and contains tar, which limits the industrial application of biomass gasification power generation technology. At present, biom...
