Problems solved by technology

Green plants absorb water and carbon dioxide during their growth, and the total amount of carbon dioxide produced in hydrogen production has achieved zero growth, eliminating the root cause of the "greenhouse effect". However, the traditional biomass hydrogen production reaction conditions are set unreasonably and cannot Realize the effect of continuous high-efficiency hydrogen production

Abstract

The invention relates to the technical field of hydrogen production in a critical fluid reaction system, in particular to a combined technical method of basic metal carbon sequestration and coal hydrogen production catalysis in the critical fluid reaction system. The method comprises the steps of S1, adding biomass, lignite and water into a reactor by using a metering pump; and S2, converting air in the reactor by using argon. Under the condition of adding the potassium salt, the gasification effect and the glucose decomposition rate of the pressure near a critical point can be improved, the water-gas conversion reaction is promoted, carbon monoxide generated in the steam reforming reaction is consumed, along with the increase of K / C, CO2 is more fully absorbed, the content of H2 in gas components is more and more, and under the condition that the temperature is 490-510 DEG C, and the reaction pressure of 25-30 MPa, the generated H2 content is high, the H2 content is reduced when the temperature is too high or too low, and the H2 content is reduced when the pressure is too low or too high, so that the continuous high-efficiency hydrogen production can be achieved under the conditions of the temperature of 490-510 DEG C and the reaction pressure of 25-30 MPa.

Description

technical field [0001] The invention relates to the technical field of hydrogen production in a critical fluid reaction system, in particular to a technical method for the combined use of base metal carbon sequestration and coal-to-hydrogen catalysis in a critical fluid reaction system. Background technique [0002] With the development of human society, the human demand for energy is increasing day by day, while the reserves of mineral energy such as coal, oil, natural gas, etc. as the main energy sources are decreasing day by day, and the pollutants discharged in the process of utilization are harmful to the ecological environment. The destruction is becoming more and more serious, and energy and environmental issues have become two major issues of general concern in the world today. [0003] With the decreasing reserves of domestic oil and coal, if there is no suitable alternative energy, it will seriously affect the long-term economic development. In addition to the effi...
