The effect of the catalytic addition of mesoporous aluminosilicate on the composition of the cracking products of natural bitumen on the Ashalchi deposit with a content of IBP-200 °C fractions of 4.6 mass % in the autoclave reactor was studied. It was demonstrated that the addition of 5 % catalyst increased destruction of resins and the yield of low-boiling fractions. It was determined that the catalyst modification with nanoscale nickel powder slowed down coke formation. At cracking of bitumen employing mesoporous aluminosilicate modified with nickel, the yield of IBP-360 °C fractions per 35.2 mass % was increased, and destruction of resins and asphaltenes was 48 % in comparison with the initial bitumen.
