. Generally, the bimetallic alumina supported catalysts (usually NiMo and less CoMo/Al 2 O 3 [ 28 ]) in sulfided form were studied for the HDO reaction of vegetable oils. There is still limited information available about the application of the non

. Recycling of the MCM-41 supported catalyst Easy recyclability and the prolonged retention of catalytic activity are very important for industrial applications. In order to test the reusability, we carried out the coupling of iodobenzene or 1-iodo-3

acid strength of the supported catalyst was increased with an increasing loading amount of TPA from 5 up to 10 wt% and is constant for higher loading amounts. These results confirm maximum dispersion of TPA on the MCM-41 for the 10 wt% catalyst which is

/Al = 2.43) were obtained from Nankai University catalyst Co., Ltd. The supported catalysts were prepared by impregnating the NaY zeolite with an appropriate amount of the aqueous solution of KNO 3 for 12 h. The obtained mixture was dried in an oven at

explained as follows. During the preparation of the supported catalyst, tungstic acid, H 2 O 2 and H 3 PO 4 were first mixed according to the ratio in the literature [ 4 ] in order to get the active species of [(PO 4 ){WO(O 2 ) 2 } 4 ] 3− . Second, the

and may not be suitable for commercial application. For the impregnation method, the solvents used during the synthesis often play important roles in the courses of precipitation and calcination of supported catalysts. Different solvents can determine

]. However, the alumina supported catalyst for dehydrogenation may suffer from its acidity. It is generally accepted that the side reactions of the alkane dehydrogenation such as isomerization and catalytic cracking may occur on the acid sites. If there are
