Feasibility Assessment for the Use of Various Hydrocarbon Feedstocks to Produce Rubber Solvent

Аннотация

Results from a study of the compositions of gas condensates of Urengoi field and liquid pyrolysis products of Muna brown coal of Altai Region are used to select a feedstock for producing rubber solvent (Nefras C2 80/120, Kalosha rubber solvent) in the highest yield. The studied feedstock is fractionated in a laboratory distillation column. The hydrocarbon composition of the fraction corresponding to the Nefras C2 80/120 boiling-point range is determined in compliance with TU 38.401-67-108-92 specifications. A method consisting of dynamic adsorption on silica gel is proposed for removing unsaturated and aromatic hydrocarbons from the Nefras C2 80/120 fraction.
