Abstract

The invention provides a biomass direct power generation fuel cell and a CO2 utilization system and method. The system comprises a biomass direct power generation fuel cell system I and a CO2 utilization system II, and is used for converting chemical energy in biomass into electrical energy and converting CO2 gas generated by the biomass direct power generation fuel cell system I into hydrocarbonfuel highly selectively and directionally. The method comprises the following steps: the biomass degradation process is accompanied with reduction of Fe<3+>, electrons are provided while Fe<2+> on ananode is oxidized, electrons are received on a cathode, VO<2+> is reduced, and currents are generated by directional movement of electrons; CO2 produced in the process of biomass degradation is hydrogenated to produce methanol, and methanol is subjected to C-C coupling reaction, and C<5+> alkane is produced. With the adoption of the method, chemical energy of biomass is directly converted into electric energy, and CO2 waste gas is converted into high-value fuel.

Description

technical field [0001] The invention belongs to the technical field of biomass energy, in particular to a biomass direct power generation fuel cell and CO 2 Utilizing the system and method thereof, specifically for establishing direct power generation fuel cells and CO using biomass 2 The waste gas can efficiently produce associated hydrocarbon fuels. Background technique [0002] The rapid development of the economy has resulted in less and less traditional petrochemical energy reserves and is becoming increasingly exhausted. The most abundant renewable resource bestowed by nature to human beings is lignocellulosic biomass. my country has abundant waste crop resources such as straw and bagasse. Therefore, how to rationally utilize the cheap and easy-to-obtain lignocellulosic biomass with high energy value is an urgent task in the field of energy research. At present, the research on the utilization of lignocellulosic biomass mainly focuses on power generation, hydrogen p...
