Automobile gasoline composite modifying agent

Abstract

The invention relates to an automobile gasoline composite modifying agent. The raw material of the modifying agent is prepared from the following components in percentage by weight: 25-50% of an octane value promoter, 30-50% of a combustion improver and 20-25% of a latent solvent, wherein the octane value promoter comprises the following components in percentage by weight: 20-45% of sec-butyl acetate, 30-40% of diisopropyl ether, 5-10% of absolute ethyl alcohol and 20-30% of methyl tert-butyl ether; the combustion improver comprises the following components in percentage by weight: 10-20% of cyclopentane, 47-50% of mixed light arene, 30-40% of alkylate and 3-6% of 1# jet fuel; and the latent solvent comprises the following components in percentage by weight: 10-30% of acetone, 25-30% of dimethoxy ethane, 20-25% of industrial isobutyl alcohol, 22.5-28% of industrial isopropyl alcohol, 1-4% of trinitromethane, 1-2% of glycol ethylene ether, 0.1-0.2% of a clearing agent polyisobutene succinimide, 0.2-0.4% of a metal deactivator T1201 and 0.2-0.4% of an antioxidant. By adopting the automobile gasoline composite modifying agent, a three-way catalyst of an organic ashless exhaust system cannot be poisoned, a fuel spray nozzle and a cylinder exhaust valve cannot be abraded, and carbon deposition and abrasive particles cannot be generated in a machine body.

Description

technical field [0001] The invention belongs to the field of petrochemical industry and relates to a composite gasoline conditioner for vehicles, which belongs to the organic ashless category. The composite conditioner is suitable for unleaded gasoline for vehicles, ethanol gasoline, and fuel oil with gasoline component mixture as base oil. Background technique [0002] At present, the tight supply and demand of oil resources directly endangers the national security of our country. Facing the increasingly prominent problem of domestic petrochemical energy supply contradictions, on the premise of ensuring the environmental requirements and meeting the emission standards of automobile exhaust pollutants, considering the following four aspects, adopt technical methods and measures to carry out effective production of existing finished gasoline The quality improvement and upgrading of the sequence have practical guiding significance and long-term development strategic significan...
