Hydrogenation Of Carbon Dioxide

A membrane reactor consisting of a reactor and a separation membrane may be suitable to provide hydrogen from hydrocarbon in order to reduce carbon dioxide. In this study, a catalytic membrane reactor, a type of membrane reactor, was designed and tested to prove if both the reactions (dehydrogenation of ethane, and reduction of carbon dioxide to carbon monoxide) occur on each side of the membrane in the reactor as expected. As membrane materials, copper-plated LaNi5 and CaNi5 were chosen. In the first step, lower hydrocarbons including ethane was dehydrogenated at one side of the membrane; another side was swept by an inert gas. In the second step, simultaneous feed of ethane (one side) and carbon dioxide (another side) was tried if both the reactions (dehydrogenation of ethane and reduction of carbon dioxide) occur. Carbon dioxide was reduced to carbon monoxide; ethane was dehydrogenated to give ethene.
