Abstract The hydrodesulfurization of gas oil is treated as a sum of parallel reactions taking place in narrow boiling range fractions. The component reactions are approximately first order for fractions with boiling ranges of 20°C and mid boiling points between 250° and 350°C. The experimental procedure involves desulfurization of the gas oil, fractionation of samples of feed and products at various residence times, and determination of sulfur concentration in the fractions. The effect of the particle size of the catalyst and of the viscosity of the oil on the reaction rate can be assessed from Thiele's equation.
