This research aims at treating mature fine tailings (MFT) with a novel pH-responsive copolymer poly (N,N-dimethylaminoethyl methacrylate-co-acrylamide-co-acrylic acid) p(DMAEMA-co-AM-co-AA). Compared with conventional polyacrylamide (PAM), the conformation and property of this novel copolymer can...

High Chromium Cast Irons (HCCIs) are widely used in mineral processing, slurry pumping and manufacturing processes, where high resistance to erosion and synergetic erosion-corrosion is required. The excellent performance of HCCIs results from their microstructure, which consists of hard carbides...

Coke formation is a major problem in the petroleum industry because of its effect on liquid yield, catalyst deactivation, and fouling of reactor internals and downstream vessels. Carbonaceous mesophase is a liquid crystalline phase which forms during cracking of heavy oil, as a subset of coke. A...
