Struben, A M.A.

A continuous process for the distillation of solid carbonaceous material, such for example as torbanite, oil shales, coal, brown coal, peat, lignite, and tar sands, comprises suspending the solid carbonaceous material to be treated in a comminuted form in a bath of a hydrocarbon carrier material maintained in bulk in an enlarged zone and having a higher boiling point than that of the desired distillate of the carbonaceous material, the relative amount of the hydrocarbon carrier being sufficient to maintain the solid material in mechanical suspension at the temperature of the distillation and to maintain such suspension in mobile condition during the operation of the process, supplying heat directly to the specific zone and thereby subjecting the suspension without substantial alteration of the distillate or the carrier to free distillation, at a temperature as high as possible while being below that at which the bulk of the carrier normally distills, thereby obtaining a maximum yield of the desired distillation products having a boiling point lower than that of the carrier while distilling over a minimum amount of the carrier, agitating the suspension, removing the distillate, subjecting the solid carbonaceous material remaining undistilled together with associated hydrocarbon carrier to a settling treatment in a separate zone, thereby effecting separation of the hydrocarbon carrier, and returning the carrier to the bath.
