FIELD: oil chemistry. SUBSTANCE: method involves supplying gaseous reactants into layer of particles suspended in liquid. Gaseous reactants react in suspension to produce liquid and gaseous products. Liquid product forms, in conjunction with liquid, suspensions, suspension layer liquid phase. Gaseous product and unreacted gaseous reactants are released from suspension layer and go up, together with entrained solid particles and liquid phase, as gaseous phase into free space above suspension layer. Gaseous phase is subjected to treatment by distillation and, possibly, washing in free space for separating entrained solid particles and liquid phase from gaseous phase. Separated entrained solid particles and, possibly, liquid phase are returned into suspension layer. Treated gaseous phase is discharged from free space. EFFECT: simplified process of separating hydrocarbon products. 20 cl, 4 dwg, 1 tbl
