Study of Controlled Cracking of Heavy Oils.

摘要

Cracking of high molecular weight hydrocarbons (hexadecane, heavy paraffins C 21 to C 27,6-methyl eicosane and 1-phenyl dodecane) and especially saturated mixtures of vacuum distillates of crude oil from Kirhuh (Irak) is studied. A molecular mechanism is involved for cracking at moderate temperature, a low volume of gas is obtained and the ratio of paraffins/olefin is high in the liquid phase. In moderate cracking with hydrogen the ratio paraffins/olefins increase with hydrogen pressure. Heavy oil hydrocracking obtained is simpler than catalytic hydrocracking. 21 refs.
