A Pd/Ag tubular membrane reactor for methane dry reforming: a reactive method for CO 2 consumption

Abstract

This paper focuses on methane reaction with carbon dioxide to perform the dry reforming reaction in the temperature range 350-450° C during time. It is well known that CO 2 in the atmosphere is the main cause of the greenhouse effect world-wide: several strategies are proposed for its consumption, for example pumping into subsoil (exhaust oil reservoirs) or into sea background. In this work, we propose CO 2 consumption via chemical reaction with methane. In particular, the reaction of dry reforming of methane to produce syngas was carried out first in a traditional reactor, and subsequently in a membrane one. A porous Pd/Ag tubular membrane has been used for this purpose. Both reactors have been compared in terms of experimental results regarding methane and carbon dioxide conversions, and carbon monoxide and hydrogen selectivities. The experimental results achieved have also been compared with what we found in the literature.
