Abstract

The invention belongs to the field of petrochemical industry, and particularly relates to a primary oil aid, and primary oil and a preparation method thereof, wherein the primary oil aid comprises anantioxidant, a corrosion inhibitor, a detergent dispersant and a cosolvent, has good corrosion resistance, can be adsorbed on the inner surface of an engine so as to prevent the corrosive components in an oil product from corroding the engine, protect the engine and prolong the service life of the engine, and has good oxidation resistance. According to the invention, by combining the primary oil aid, isopentane, isohexane, isooctane, alkylated gasoline, methyl tert-butyl ether, raffinate oil and toluene to obtain primary oil, the primary oil aid can react with the unstable free radicals in theprimary oil to terminate the chain reaction in the fuel oxidation process and eliminate the free radicals, so that the primary oil is in a stable state, the storage time of the engine and the oil product is prolonged, and the good cold starting performance, the combustion performance and the power performance are achieved; and after the primary oil is combusted, the combustion efficiency of the engine is high, the oil consumption is low, and the tail gas emission is little.

Description

technical field [0001] The invention belongs to the field of petrochemical technology, and in particular relates to a primary oil additive, primary oil and a preparation method thereof. Background technique [0002] The initial oil is the first barrel of fuel oil for the engine. After the new car is off the assembly line, a certain amount of fuel oil needs to be added. In order to better match the engine demand and improve fuel utilization efficiency, the initial oil needs to have better cold start performance and combustion performance. , power performance, so it is necessary for the initial oil to have good adaptability to the engine; at the same time, due to the particularity of the initial oil use conditions and the uncertainty of the service cycle, the anti-rust performance and stability of the initial oil are also particularly important, and This performance is difficult to improve through simple component adjustment, so it is necessary to add certain additives to impr...
