    摘要： Low sulfur gasoline is produced from an olefinic, cracked, sulfur-containing naphtha by treatment over an acidic catalyst, preferably an intermediate pore size zeolite such as ZSM-5 to crack low octane paraffins and olefins under relatively mild conditions, with limited aromatization of olefins and naphthenes. This is followed by hydrodesulfurization over a hydrotreating catalyst such as CoMo on alumina. The initial treatment over the acidic catalyst removes the olefins which would otherwise be saturated in the hydrodesulfurization, consuming hydrogen and lowering product octane, and converts them to compounds which make a positive contribution to octane. Overall liquid yield is high, typically at least 90 percent of higher. Product aromatics are typically increased by no more than 25 weight percent relative to the feed and may be lower than the feed.

    摘要： Deposits on intake valves in gasoline internal combustion engines are reduced by an additive for fuel compositions comprising a mixture of (1) a polyalkylene succinimide, (2) a polyalkylene and (3) a mineral oil. The invention also comprises a fuel composition made up of a major amount of liquid hydrocarbon fuel such as gasoline or diesel and a minor amount of the aforesaid mixture. In still another aspect the invention comprises a method for removing and/or preventing engine deposits which adversely affect the performance of gasoline powered engines by running the engine with a fuel containing an effective amount of the previously described mixture.
