Abstract: Lubricant oil compositions containing a base oil and an additive package comprising one or more wear-resistant additives. The wear-resistant additives can be (a) a Group 1a alkali metal carbonate, a Group 2a alkaline earth metal carbonate, or a mixture thereof; (b) Group 1a alkali metal sulfate, a Group 2a alkaline earth metal sulfate, or a mixture thereof; (c) a Group 1a alkali metal phosphate, a Group 2a alkaline earth metal phosphate, or a mixture thereof; (d) Group 1a alkali metal carboxylate, a Group 2a alkaline earth metal carboxylate; or (e) a combination of (a), (b), (c), and (d). The wear-resistant additives are in the form of nanoparticles.

Abstract: A lubricant composition. The lubricant composition includes (a) a phenate, a sulfonate, or both; and (b) a base composition wherein the base composition is (i) a metal carbonate and a metal sulfate, (ii) a metal sulfate and a metal phosphate; (iii) a metal sulfate and a metal carboxylate; (iv) a metal phosphate and a metal carboxylate; or (v) three-way or four-way combination of a metal sulfate, a metal carboxylate, a metal phosphate, and a metal carbonate; and (c) a lubricating oil or a grease.

Abstract: Lubricant oil and grease composition containing an additive package comprising wear-resistant additives in the form of nanoparticles, wherein the additives are a carbonate selected from the group consisting of a carbonate of a Group 1a alkali metal and a carbonate of a Group 2a alkaline earth metal, a sulfate of a Group 1a alkali metal or a Group 2a alkaline earth metal, a phosphate of a Group 1a alkali metal or Group 2a alkaline earth metal, a carboxylate of a Group 1a alkali metal and a carbonate of a Group 2a alkaline earth metal, or a combination thereof.

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.
