Abstract

The invention discloses a light hydrocarbon fuel composition for a vehicle. The light hydrocarbon fuel composition comprises the following components in parts by weight: 500-600 parts of stable light hydrocarbon (octane site in a research method is greater than 92 #), 80-120 parts of isobutanol, 180-340 parts of aromatic hydrocarbon, 130-150 parts of xylene, 200-305 parts of isooctane, 0.25-0.5 part of lanthanum isooctanoate, 0.5-0.7 part of biphenyl, 0.1 part of a metal corrosion inhibitor and 0.1 part of an antioxidant. The stable light hydrocarbon is oil refinery downstream byproducts or methanol to olefin (MTO) and coal tar hydrogenation stable light hydrocarbons; the molecular formula of the isobutanol is C4H100; the aromatic hydrocarbon is a mixture of methylbenzene, dimethylbenzene and trimethylbenzene or one or two of methylbenzene, dimethylbenzene and trimethylbenzene for blending gasoline; the isooctane is alkylated oil and is also called isomer octane, and the research octane number is 98-100; and the metal corrosion inhibitor is benzotriazole. The light hydrocarbon fuel composition for the vehicle can improve power and reduce gasoline consumption; and emission of tail gas pollutants is reduced.

Description

technical field [0001] The invention relates to the technical field of light hydrocarbon fuel for vehicles, in particular to a composition of light hydrocarbon fuel for vehicles. Background technique [0002] In 2015, the Shanghai Municipal Bureau of Technology and Quality Supervision issued the Shanghai local standard DB31 / 385-2015 "Light Hydrocarbon Fuels for Vehicles". The stable light hydrocarbon components extracted from olefins (MTO) and stable light hydrocarbons hydrogenated from coal tar are used as base oils and effective additives that can improve its anti-knock performance, stability, and detergency. It is suitable for ordinary gasoline vehicles. [0003] In the actual implementation process, it was found that stable light hydrocarbons are low-density, low-octane, and extremely volatile light hydrocarbons, which can only be used with higher octane numbers. Isobutanol is a multi-carbon, high calorific value, Oxygen-containing anti-knock agent, the oxygen-containi...
