Abstract

The invention discloses a diesel additive, and belongs to the field of chemical engineering. Aiming at problems of the conventional diesel additives, the invention provides a multifunctional diesel additive. The diesel additive consists of the following components: a cetane number improver, a stabilizer, a disperser, a cleaning agent, an antismoke agent and a diluent. The diesel additive can improve the cetane number of diesel to a great extent. Dialkoxy alkane can be decomposed when meeting light, heat and metal ions, so N,N-dimethyl(tetradecyl)amine is selected as the stabilizer to prevent the dialkoxy alkane from being decomposed, and the stability of the dialkoxy alkane in the diesel is kept. The cleaning agent is N,N-bis(salicylidene)-propanediamine, and can clean carbon deposition on a fuel injection pump, a fuel spray nozzle and a piston ring of a diesel engine to keep a smooth oil line, so that the combustion performance and economic performance of the diesel engine are improved. The antismoke agent has a good combustion-supporting antismoke effect, so that a fuel is fully combusted, the tail gas emission of the diesel engine is greatly reduced, and requirements of environmental protection and energy conservation are met.

Description

technical field [0001] The invention belongs to the field of chemical industry. Background technique [0002] After petroleum is processed and refined, various components and petroleum products are produced, most of which cannot be directly shipped as commodities and need to be blended. The purpose of fuel oil blending is to combine the products obtained by the production equipment with the requirements of national construction for commodity varieties and quality requirements, to reconcile some physical and chemical properties of oil products, and to meet the use requirements of various machines and tools. Oil blending can usually be divided into two categories: one is the blending of oil components, that is, two or more component oils are blended into base oil or finished oil in proportion; the other is the blending of base oil and appropriate additives. Liquid petroleum fuel blending mainly includes vehicle gasoline blending, diesel blending, jet fuel blending, ship fuel ...
