英文摘要： The resource utilization of metallurgical process furnace gas and greenhouse gas is attracting increasing attention as one of the most effective measures of reducing carbon emission in the future. The new method of coke oven gas and carbon dioxide utilization technology based on dual-phase mixed conducting membrane reactor is very promising in the related field. The stability of the membrane reactor is strongly affected by the composition of materials, catalyst performance, carbon dioxide and the multicomponent gas mixture of coke oven gas. However, the further researches have been rarely reported before. This work deeply studies the oxygen permeation degradation behavior of dual-phase mixed conducting membrane reactor coupled with the utilizations of coke oven gas and carbon dioxide, adequately investigating the effects of the composition and structure of membrane reactor, catalysts, and multicomponent gas mixture. The contents are as follows: the development and characterization of the new membrane materials, the evolving regular and corrosion mechanism of the materials under complex atmosphere; the controllable synthesis and the optimization of the high performance nano catalytic materials and its regulation mechanism to target reaction products; the oxygen permeation process and the reaction path of CO2-O2 mixed reforming of methane in the membrane reactor. The present project mainly aims at revealing the stability enhancement mechanism of dual-phase mixed conducting membrane reactor, which can help to lay the theoretical and technical foundation for the optimization and development of the permeable reactor in the resource utilization of coke oven gas and carbon dioxide.
