USY zeolites of varying Si/Al ratios were used as support for Mo, NiMo, CoMo and NiW catalysts. Both the effect of variation of Si/Al ratio of the zeolite and Mo content on support at fixed Si/Al ratio were studied. The catalysts were examined by XRD, oxygen chemisorption and TPR techniques. The hydrodesulfurization and hydrogenation reaction studies indicated that these catalysts are more active than Y-AI2O3 supported catalysts and the increase in activities may be attributed to an increase in Mo dispersion and reducibility. It was found that oxygen uptake correlates well with the catalytic activity.

The series will deal with both heterogeneous and homogeneous catalysis, and will include processes in the heavy chemicals and oil refining industries, the smaller-scale manufacture of pharmaceuticals, and various aspects of pollution control. The series editors would welcome any comments on the series and suggestions of topics for future volumes. 

Most organic commodity chemicals are currently made commercially from ethylene, a product of oil refining. In the next several decades, we may see a shift toward other carbon sources for these chemicals. Either coal or natural gas (CH4) can be converted with steam into CO/H2 mixtures called water-gas or synthesis gas and then on to methanol or to alkane fuels with various heterogeneous catalysts (Eq. 12.19). In particular, the Fischer-Tropsch reaction converts synthesis gas to a mixture of long-chain alkanes and alcohols using heterogeneous catalysis. 

High throughput screening is one of the hot topics in heterogeneous catalysis. Advanced experimental techniques have been developed to screen and develop solid catalysts for gas-phase systems. However, for catalytic three-phase systems, rapid screening has got much less attention [1-6]. Three-phase catalysis is applied in numerous industrial processes, from synthesis of fine chemicals to refining of crade oil.
