Preparation of the Highly Dispersed Pt/Zeolite Catalysts in Methanol-Water Mixture and Evaluation of their Catalytic Activity

A series of platinum-zeolite based catalysts were prepared by reduction of Pt-salt with a methanol-water mixture using individual HY-zeolite or its modified composites both as protective agents and catalyst supports. The prepared composites have been tested as catalysts in n-C10-hydroconversion reaction in the range of temperature 180–270 °C and at atmospheric pressure. Different parallel and consecutive isomerization and cracking reactions take place in hydroconversion of n-decane over prepared catalysts producing different mono- and multi-isomers and cracked products. The impact of the temperature and conversion degree to the distribution of hydroconversion products has been studied. Special attention was paid to synthesis of high-octane fuel components from n-decane.
