As the Canadian supply of light crudes has diminished in recent years, reยฎneries have necessarily been required to deal with difยฎcult to process oilsands bitumens and heavy oils. Bitumen in particular exhibits unique behavior during upgrading; nearly 50% (w/w) of the feedstock is an intractable resi

It has been proved in our previous study that during the melt-blending of an epoxy oligomer based on the diglycidyl ether of bisphenol-A (DGEBA) with polycarbonate (PC) at 200ยฐC, the secondary hydroxyl groups in the DGEBA react with the carbonate groups in PC through transesterification, resulting i
Aslphaltenes are difficult to characterize by any procedure that involves chromatography. In an attempt to obtain useful information on unfractionated asphaltenes and their structural relations to their parent coals, asphaltenes from a set of eight coals of hvA rank and different coalification histo
