Abstract
The paper describes the results of studies on improving nickelia-vanadia-based catalyst for ethyltoluenes dehydrogenation and the features of the process for mesitylene production on its base. This process (dehydrotreatment of C9-aromatics) includes catalytic removal of ethyltoluene impurities from C9 fractions of coal pyrolysis products, followed by isolation of the target product by two-step fractionation of the dehydrogenate obtained. The optimal composition of the catalyst for this process has been determined, and operating conditions for catalytic treatment of C9 fractions in its presence have been chosen. The advantage of using coal-derived C9-aromatics as feedstocks for the proposed dehydrotreatment process, in comparison with analogous petroleum-derived C9 fractions, is emphasized. The technological scheme of the given process is presented, and its performance characteristics are compared to corresponding parameters of some alternative methods of mesitylene production. Relative simplicity, feasibility, good quality of commercial mesitylene produced (of 98.8% purity), combined with high efficiency of its recovery from C9 fractions of hydrocarbons (up to 82.5% from its resources in the feedstock), are the essential features of the technology proposed.
