Abstract:
A high performance lubricating grease effectively lubricates and greases front-wheel drive joints. The front-wheel drive grease has excellent extreme pressure properties and antiwear qualities and is economical, non-toxic and safe. In one preferred form, the front-wheel drive grease comprises a base oil, a thickener comprising polyurea and calcium complex soap, and an additive package comprising tricalcium phosphate and calcium carbonate.

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 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 oxidisable 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. A hydrogenation catalyst precursor comprising a hydrocarbonaceous feedstock, a sulfide particle precursor fluid, and an oxide particle precursor fluid is also described.

Abstract:
A process is provided for lubricating and protecting bearings in steel and process mills. In the process, metal is processed in the mill and conveyed on caster rollers. The caster rollers are lubricated with a special grease which enhances the longevity of the rollers, protects the rollers from rust and corrosion, and prevents the grease from leaking out of the rollers. In the preferred form, the grease comprises a water-resistant polymer to prevent the grease from washing out of the rollers and bearings when the metal workpiece is quenched with a high pressure water spray.
