Study On The Characateristics Of Methane Coupling Of Oxygen And Carbon Dioxide Reforming In Membrane Reactor

Global warming and the energy crisis as two serious problems, more and moreattention of governments, these issues will need to change all types of researchers andcontinue to develop new energy using patterns. Affordable without the key to solve twomajor problems are coming from the energy source for in-depth research. Methane andcarbon dioxide as a greenhouse effect is the most important material, their research hasincreasingly become a hot spot in the world researchers. Methane coupling of oxygenand carbon dioxide reforming is using carbon dioxide, methane and oxygen as reactionraw material to produce a certain proportion of hydrogen and carbon monoxide, singlesat an appropriate catalyst surface. This reaction can be as a method of turning waste ofcarbon dioxide into treasure, while can be resolved using both process conversion rate isnot high, energy consumption is too high, and mitigation of global warming’s seriousproblem.This paper mainly uses methane and carbon dioxide as the reaction material,at thesame time adding the appropriate oxygen and water vapor to analyze the characteristicsof reaction of methane in the the reactor. From theoretical and experimental aspects, Iexamined operating conditions and the impact of raw materials proportion on reformingreaction characteristics in the general reactor and membrane reactor.Analysis results shows: Temperature, oxygen to carbon ratio, methane to carbondioxide ratio, and whether the presence of oxygen has the extremely important influenceon the conversion of methane and carbon dioxide in two reactors. When temperaturerises, the conversion of methane and carbon dioxide conversion rate will increasewhether in ordinary reactor or in the membrane reactor. For ordinary reactors,oxygen-carbon ratio changes, methane conversion rate of a rising trend, while carbondioxide conversion rates shows a declining trend, experimental results and theoreticalcalculations have a more uniform changes, methane conversion rate rises to67.4%from97.5%in the experiment, carbon dioxide conversion rate fall from87.7%to38.8%.Oxygen to carbon ratio can be used as a factor in regulating content, but regulation isrelatively narrow in scope. In membrane reactor, when oxygen-carbon ratio increasedfrom0.1to0.8, methane conversion rate rises from58.34%to88.29%, carbon dioxideconversion rate falls from90.51%to76.49%.When carbon dioxide to methane ratio increases,for ordinary reactors, the performance of the methane conversion rate rise, the conversion of carbon dioxideshows a downward trend.For the membrane reactor, when the carbon dioxide tomethane ratio from0.1to1.9, the methane conversion rate exhibits a rising trend in thebeginning,the value tends to be stable after that compared to theoretical results, themethane conversion rate tends to a stable value corresponding to the transfer of carbondioxide to methane ratio from1.1to1.3.
