Publication number: 20130334102Abstract: The invention is directed towards a method of removing mercury bearing species from a hydrocarbon containing fluid. The method comprises the steps of: i) adding dithiocarbamate polymer to the fluid in an amount such that the number of mercury bonding sites on the polymer exceeds the amount of mercury atoms by at least 10% and ii) removing the mercury bearing dithiocarbamate polymer with a water/oil separation device. The invention relies upon an unexpected reversal in the solubility of dithiocarbamate polymer at very high concentrations.

Publication number: 20120168350Abstract: An improved process for preparing a slurry catalyst for the upgrade of heavy oil feedstock is provided. The process employs a polar aprotic solvent to mix with the inorganic metal precursor feed to form an oil-dispersible inorganic metal precursor, at a weight ratio of solvent to inorganic metal precursor of 1:1 to 10:1; the oil-dispersible inorganic metal precursor is subsequently sulfided forming the slurry catalyst. In one embodiment, the sulfiding is in-situ upon mixing the oil-dispersible inorganic metal precursor with a hydrocarbon diluent containing a heavy oil feedstock under in-situ sulfiding conditions.Type: ApplicationFiled: December 20, 2011Publication date: July 5, 2012Inventors: Oleg Mironov, Alexander E.
