Multiple Use of Silica-Alumina Catalyst in Hydrocarbon Resins Production

Abstract

Hydrocarbon resins synthesis from C9 fraction of liquid products of diesel fuel pyrolysis when using activated bentonite clay as a catalyst at multiple use of the latter has been studied. Process is analysed in terms of the resin yield and its properties including average molecular weight, colour and bromine number. The results obtained are explained considering the catalyst characteristics. The process when using the used catalyst undergone to high temperature regeneration has also been carried out. The catalyst regeneration has been studied by thermogravimetric analysis. Reasonable application areas of the used catalyst are suggested.
