Hydrocracking of Oil Sand Bitumen with a Fine Powder Cobalt Molybdate Alumina Catalyst

Abstract

Hydrocracking of oil sand bitumen was carried out in a bench scale suspended-bed reactor to produce synthetic crude oil.
Several mechanical problems in the test plant were solved f or the treatment of slurry mixture of bitumen and fine powder catalyst, and the experimental runs were carried out smoothly. The operating conditions were as follows: Reaction temperature, 450°C Reaction pressure, 70 and 100 kg/cm²; LHSV, 0.83 and 0.89 respectively Catalyst/feed=3/100 by weight.
The liquid product yields were above 91 wt%. The fraction boiling below 340°C was about 60 wt% to the product oil, and it contained mainly kerosene and light gas oil.
