STUDY ON CATALYTIC ROLES OF TUNGSTEN CARBIDE NANOSPHERES FOR CH₄/CO₂ REFORMING OVER NI BASED CATALYSTS

Niu Liang, Jin Xing

ABSTRACT:In this paper, WO3 nanospheres are used carriers and Ni-WCx nanospheres are synthesized via the method of incipient impregnation and temperature programming carbonization with the content of Ni is 10%. The presence of Ni promotes the cracking of CH4, while the activation of CO2 takes place on WCx. Thus, the deactivation due to carbon accumulation or WCx oxidation could be avoided.
