英文摘要	National Natural Science Foundation of China [51076157]; National 863 Plan [2010AA101606]; Chinese Academy of Sciences [KSCX2-YW-G-063]; Ni/HZSM-5 catalysts calcined at different temperatures were used in the isoparaffin production by aqueous phase processing of sorbitol and characterized by N(2) physical adsorption, temperature-programmed reduction (H(2)-TPR), temperature-programmed desorption of ammonia (NH(3)-TPD) and Raman techniques. The effect of calcination temperature of the catalysts on the catalytic performance for the reaction was investigated. The activity test results indicated that the maximal i-C(6)H(14) selectivity of 45.4% and the total i-C(6)H(14) and i-C(5)H(12) yield of 32.3% were obtained over the catalyst calcined at 500 degrees C, which exhibited the optimum surface area and pore structure with 100% of the reducibility of Ni species on the surface of HZSM-5. In addition, the amount and the strength distribution of acidic surface sites of the catalyst decreased with the increase of calcination temperature at 500 degrees C above. All these factors result in an increase in the formation of isoparaffin. (C) 2011 Elsevier Ltd. All rights reserved.
