Heavy oil upgrading using magnetic molybdenum …
the magnetic catalysts have received much attention due to the easy recovery of catalysts [9, 10]. So in this work, a kind of magnetic molybdenum disulfide catalyst (Fe 3 O 4 @SiO 2 @MoS 2) was synthesized. The hydrocracking and viscosity reduction reactivity of the magnetic catalyst for the Canadian oil sand asphalt were studied.
Optimizing the performance of the RER magnetic separator …
Feed fractionation of a silica sand sample to a rare earth roll separator (RER) magnetic separator was found to be much more favorable for separation than the whole batch. The performance of the separator depends on both the size and the size distribution of the feed.
