Abstract

The results of a study on the use of a bifunctional NiMo\Al2O3-USY catalyst in the hydrotreating of chlorine-containing thermolysis oil are presented. It is shown that when using two different solvents (straight-run vacuum gas oil and straight-run diesel fraction) as feedstock, the catalyst exhibits high activity in hydrogenation reactions and the conversion of heteroatomic compounds. The catalyst enables the removal of chlorine-containing compounds with a high degree of conversion (approximately 95%). Using the NiMo\Al2O3-USY catalyst in the hydrotreating of a mixture of thermolysis oil and straight-run diesel fraction reduces the content of n-alkanes and lightens the fractional composition of the resulting product.
