Conclusions 1. The introduction of silicon dioxide into an alumina-cobalt (nickel) molybdenum catalyst results in an improvement of its structure: an increase in the volume and in the average pore radius and a 1.5 increase in the mechanical strength. 2. As the silicon dioxide concentration in the catalyst is increased its cracking and isomerizing capacity increases resulting in an increase in the depth of conversion of the raw material, an increase in the ratio of the iso-and normalhydrocarbons in the gaseous and liquid products,and a decrease in the setting temperature for the diesel fractions. 3. For prolonged operation with the heavy vacuum distillate the catalyst, containing 20% silicon dioxide, loses its hydrodesulfurizing activity faster than the industrial catalyst and that containing 10% silicon dioxide.
