Abstract: An overbased calcium sulfonate grease composition and method of manufacture comprising added alkali metal hydroxide alone or in combination with (a) calcium hydroxyapatite and/or added calcium carbonate used as calcium containing bases for reacting with complexing acids) and/or (b) at least one delay period between the addition of water as a converting agent and addition of a portion of a non-aqueous converting agent. A delay period may involve the period of time it takes to adjust the temperature of the mixture, a period of time during which the mixture is held at a temperature or within a range of temperatures, and multiples and any combination thereof. These calcium sulfonate greases have improved thickener yield and high dropping points compared to greases made without added alkali metal hydroxide and delay between the additions of water and a non-aqueous converting agent, particularly when a poor quality overbased calcium sulfonate is used.

Abstract: The present application provides a method for removing drag reducer additive (“DRA”) from liquid hydrocarbon fuel. The method comprises: providing contaminated liquid hydrocarbon fuel comprising an initial concentration of DRA; contacting the contaminated liquid hydrocarbon fuel with a quantity of fresh attapulgus clay under conditions effective to produce decontaminated liquid hydrocarbon fuel comprising a reduced concentration of the DRA; said fresh attapulgus clay being effective to remove about 10% or more of a target DRA when 1 g of the fresh attapulgus clay is added in increments of from about 0.02 gram to about 0.1 gram, with agitation, to 100 ml. of contaminated liquid hydrocarbon fuel comprising from about 8 to about 9 ppm of the unsheared target DRA.

Abstract: A method for converting a hydrocarbonaceous feedstock to a lower boiling temperature product is described which comprises suspending metal sulfide particles and oxide particles in a reaction zone including hydrogen and the hydrocarbonaceous feedstock at hydrocracking conditions. The metal sulfide particles and the oxide particles are introduced into the reaction zone through particle precursor fluids which precipitate upon heating to form the particles. The metal sulfide particles contain sulfidable transition metals. The oxide particles contain oxidizable elements such as magnesium, aluminum, silicon, phosphorous, calcium, scandium, titanium, gallium, germanium, zirconium, cerium, and mixtures thereof and are not hydrogenation catalysts under the reactor conditions. The oxide particles resist being chemically reduced by reducing agents in the reaction zone. Surprisingly, the presence of the oxide particles is associated with a significant reduction of coke production in the reaction zone.
