METHOD OF PROCESSING HIGH-MOLECULAR RESIDUES OF PETROLEUM PROCESSING Russian patent published in 1996 - IPC

Abstract RU 2064959 C1

FIELD: petroleum chemistry. SUBSTANCE: petroleum asphaltenes were mixed with technical sulfuric acid and vat residues of recovered dimethyldioxane from rectification stage at isoprene synthesis by dimethyldioxane decomposition at 180-200 C for 120-180 min. Mixing is carried out at ratio, wt.-%: petroleum asphaltenes 78-82; vat residues 10-12, and technical sulfuric acid - the rest. EFFECT: improved method of processing. 3 tbl
