At nearest perspective dominant position as the main source motorized fuels and raw materials petrochemical production will continue behind oil [5].
This process is called thermocatalytic, as clay and other materials of bituminous rocks inevitably have a catalytic effect on the reaction.
In Russia, the processing of heavy bituminous oil-per unit of raw materials and per unit of marketable products-still requires higher costs.
