<p>A process for improving the upgrading/conversion of hydrocarbonaceous materials such as coals, petroleum residual oils, shale oils and tar sand bitumens. In the process, the free radicals formed from thermal cracking of the hydrocarbons are reacted with the free radicals formed by the thermal cracking of a free radical forming chemical reactant, such as diemthyl ether, to yield stable low molecular weight hydrocarbon distillate products. The hydrocarbonaceous feed material is preheated to a temperature of 600-700.degree.F and the hydrocarbon and the free radical forming chemical, such dimethyl ether, are passed through a flow reactor at temperature of 750-900.degree.F, pressure of 200-1000 psi, and liquid hourly space velocity of 0.3 to 5.0 LHSV. Free radicals formed from the hydrocarbon feed material and from the ether material react together in the ractor to produce low molecular weight hydrocarbon liquid materials. The weight ratio of ether material to hydrocarbon feed material is between about 0.3 and about 2.0.</p> |
