Abstract: Bitumen-containing material is processed by distillation with a solid heat-carrier with subsequent gasification of the distillation residue and combustion of the gasification residue in an aerofountain furnace. During gasification, the formed flue gas and ash are heated and part of ash is used as the heat-carrier. The flue gas and ash are withdrawn from the process simultaneously in the form of their suspension in air, from which the heat-carrier is isolated for the distillation process, the consumption of the heat-carrier being controlled by withdrawing part of the suspension containing fine fraction of ash before the heat-carrier is isolated.

Abstract: A fuel composition which comprises a high-boiling petroleum fuel and an additive. The additive incorporates compounds of elements Mg, and/or Ca and/or Mn, and/or Al, and/or Fe and also an ash-containing resin.The additive is prepared by thermal processing of a solid fuel with the formation of a dust-containing vapor-gas mixture. Thereafter, a resin is condensed from the vapor-gas mixture which is incorporated with the above-mentioned compounds of said elements and, finally, the resin is discharged along with the deposited dust.
