    摘要: A method is provided for removing carbonaceous ash deposits from a light hydrocarbon gas combustion chamber. The method comprises contacting the gas combustion chamber containing the ash deposits with alkali metal hydroxide. The alkali metal hydroxide causes the ash to soften and in one embodiment, to flake off, often down to bare metal. The combustion chamber can be part of a spark-ignited engine run on natural gas or propane.

    摘要: Gear lubricant with a low Brookfield Ratio, comprising: a base oil having sequential carbon atoms, low aromatics, greater than 20 wt % molecules with cycloparaffins and a high ratio of monocycloparaffins to multicycloparaffins; less than 22 wt % of a second base oil having less than 40 wt % molecules with cycloparaffins and a lower ratio of monocycloparaffins to multicycloparaffins; a pour point depressant, an EP additive; and less than 10 wt % VI improver. Gear lubricant with a low Brookfield Ratio, comprising a first base oil having low aromatics and high VI; less than 22 wt % of a second base oil with a lower VI; a pour point depressant; and an EP additive. Gear lubricant having a low Brookfield Ratio comprising: an FT derived base oil; a pour point depressing base oil blending component; and an EP additive. Processes for making gear lubricants with low Brookfield Ratios. Method for reducing Brookfield Ratio.
