Abstract
In this paper, hydrodesulfurization
(HDS) of crude oil in the three-phase slurry reactor
over cobalt – molybdenum catalyst (CoMo / ɣ-
AL2O3) is studied. Effects of space velocity and
length of reactor on the conversion rate and
catalyst effectiveness for HDS process have been
investigated. Kinetics of the reaction rate for this
process is primarily and Arrhenius equation for
the rate constant is used. The results show that
the effectiveness factor for catalyst along the
length of reactor is decreased about 83%.
By increasing liquid velocity from 4 to 10 1/s,
the conversion of sulfur components is decreased
about 22% at the temperature of 523 K. At the
same temperature, by increasing liquid velocity
from 36 to 84 1/s conversion is reduced to 25%.
The results of the variation of the dimensionless
reaction rate against conversion show that with
increasing conversion, the reaction rate
decreases and the reaction is stopped when the
conversion is 100%.
