| Popis: | An e.s.r. study of THF-insoluble fractions obtained after coal hydroliquefaction has allowed the parameter dR° to be defined. This parameter reflects the ability of the reactive medium to hydrogenate radicals formed during thermal cleavage of coal, and varies from −36% to +60%. A value of 100% would indicate optimum hydrogen transfer between the reactive medium and the coal products. |
