The products of the radiation-stimulated dry distillation of coniferous hydrolytic lignin at a residual pressure of 1–5 torr have been obtained and analyzed. The tar distilled off under irradiation conditions predominantly contains phenols, including about 33% benzenediols. Among the benzenediols, the fraction of catechols is 69%. Phenoxyl radicals are considered to be direct precursors of the phenolic...
The electron beam-initiated cracking of a mixture of C17–C120 paraffins at 350–370°C has been studied. The cracking regime implied simultaneous feedstock irradiation and rapid distillation of fragmentation products from the irradiation zone. The distillate was a mixture of 61.5 wt % alkanes and 38.5 wt % alkenes. The product molecule contained on average 13 carbon atoms. The gasoline fraction in the...
