Abstract: A novel way of synthesizing pure WC as well as SiC powders by in situ carbo-thermal reaction of sugar cane and tungstic acid or Si is presented. Tungsten and silicon carbide bodies were sintered at 1450oC under vacuum. The preparation process, catalytic activity, microstructure, and phase composition of the prepared bodies were investigated and characterized. The resultant WC and SiC architecture showed a homogeneous fine-grained microstructure and good distribution of closed pores. The WC bodies exhibit high activity for dehydrogenation of cyclohexane to cyclohexene with selectivity of 96% at 200° to 350°C.
