摘要: Bulk tungsten carbide catalysts are prepared by direct carburization/reduction of trioxide in methane-hydrogen mixtures. The catalytic properties such have been studied several authors. porous structure these is adsorption N2, Kr, CF4 and neohexane. Adsorption isotherms hysteresis loops for the suggest presence a microporous made parallel plates distant approximately 20 A. These results compared to those obtained using hydrogen oxidation where condensation was observed.
