PREPARATION OF ECOFRIENDLY RUBBER PLASTICIZER BYHYDRIFINING-FURFURAL EXTRACTION FROM NAPHTHENIC-BASE HVGO

Abstract

Abstract: The environmental friendly rubber plasticizer with high CA value was prepared in laboratory by two kinds of combined processes: hydrofining-single stage furfural extraction and hydrofining-two stage furfural extractions, using naphthenic-base HVGO of SZ36-1 crude as raw material. The results showed that both of the combined processes could produce the rubber plasticizers meeting the specifications of national standard. Rubber plasticizer A1220 could be produced by hydrofining-single stage furfural extraction with higher yield; while rubber plasticizer A1820 with higher CA could be produced by hydrofining-two stage furfural extractions.

Key words: naphthenic-base HVGO, furfural extraction, hydrofining, combined processed, rubber plasticizer
