Summary: | Catalysts with Ni and Pt as active metals in peleted zeolite were used for conversion of amyl alcohol, isoamyl alcohol and their mixture to hydrocarbon compounds.
The catalysts were prepared by impregnation the peleted zeolite in NiC12.6H20 and PtCI4 solution, while stirring for 24 hours then followed by oxidation with 02 gas at 350°C for 2 hours and reduced by hydrogen gas at 400C for 1 hour. Ni and Pt in catalysts were determined by AAS, specific surface area, total pore volume and gas sorption analyzer NOVA-1000 determined pore radius average. Determination of catalysts acidity was caned out by absorption of ammonia method. The activity of catalysts was evaluated in a micro reactor by flow system. Experimental temperature by varied between 300C and 400°C with the increment of 25°C. Products were analyzed by gas chromatographic and mass spectrometric method.
The result shows that Ni-Pt/zeolite is more active than Ni/zeolite can be used for converting all of the alcohol. Products for conversion are 2-pentene, 2-methyl-1-butene, 2-methyl-2-butane, cyclopentane, 3-methyl-1-butanaldehide and acetone. The highest conversion was observed on isoamyl alcohol (31.37%) at 400°C.
