Abstract
A new tungsten phosphide was successfully synthesized for the carbon dioxide reforming of methane (CH4-CO2 reforming). The catalysts were prepared by combining citric acid and temperature programmed reduction of phosphotungstate precursor, which was characterized by X-ray diffraction. This paper focuses on investigating that the influence of preparations on activity of tungsten phosphide for CH4-CO2 reforming. The activity results indicate that the activity and stability of catalyst was prepared under the proper conditions. On this basis, a new easier preparation was proposed, which was prepared by associating calcining with reduction H3O40PW12·XH2O and (NH4)2HPO4, the prepared catalyst showed a little bit worse of the activity. The activity test results of tungsten phosphide for CH4-CO2 reforming show that it produce synthesis gas with lower H2 to CO ratio than the conventional catalysis for the CH4-CO2 reforming.
