A metal trap for an FCC catalyst include pre-formed microspheres impregnated with a salt of calcium and/or magnesium and an organic acid salt of a rare earth element.

A treatment composition for remediating for remediating H.sub.2S, CO.sub.2 and other contaminant(s) in a fluid mixture of contaminated liquids and gasses comprising: a hydrocarbon based liquid; and at least one hydroxide compound dispersed or dissolved into the hydrocarbon based liquid. The at least one hydroxide compound dispersed or dissolved into the hydrocarbon based liquid constitutes 30-50 wt% of the treatment composition, the at least one hydroxide compound includes at least one of potassium hydroxide and sodium hydroxide, and a pH of the treatment composition is in a range of 13-14.0.

A process for preparation of catalyst to produce ultra-low sulfur diesel (ULSD) from high refractory sulfur feedstock. The catalyst composition comprises a modified alumina carrier, impregnated by metal of group VIB is in the range of 15-25% and metal of group VIIIB is in the range of 1-5% as oxides. The catalyst prepared in the present invention produces highly dispersed MoS2 active sites on the modified carrier. The catalyst produces ultra low sulfur diesel (ULSD) along with improved cetane, density reduction and endpoint reduction.

A treatment method for reducing contaminating agents in liquid mixtures of substituted hydrocarbons used as fuels is provided. A supersaturated mixture of ferrous oxide is combined with the hydrocarbons and mixed to form a homogenous solution. The homogenous solution is allowed to separate by means of settling and an aqueous solution is decanted to thereby produce a refined liquid hydrocarbons.
