Bio-based methanol gasoline antiknock and air drag reducing agent and preparation method thereof

Abstract

The invention discloses a knock preventing and air resistance lowering agent for bio-based methanol gasoline and a preparation method of the knock preventing and air resistance lowering agent. The knock preventing and air resistance lowering agent consists of 75-80% of knock preventing ingredient and 20-25% of air resistance resisting ingredient; and the knock preventing and air resistance lowering agent product is prepared through uniformly mixing the two functional ingredients at normal temperature. According to the knock preventing and air resistance lowering agent and the preparation method of the knock preventing and air resistance lowering agent, cleanable, environmental-friendly, reproducible and degradable petroleum yeast fatty acid is selected as a cheap additive, so that the energy is saved and the emission is reduced; and compared with the prior art, the knock preventing and air resistance lowering agent is low in cost, non-toxic, free of pollution, low in dosage and remarkable in knock preventing and air resistance lowering effect, does not contain heavy metal ingredients, such as MTBE, MMT (Methyl-cyclopentadienyl-Manganese-Tricarbonyl) and ferrocene, and cannot cause secondary pollution to environment. The knock preventing and air resistance lowering agent and the preparation method of the knock preventing and air resistance lowering agent have the advantages that the temperature of the initial boiling point (namely a first drop of a boiling range) of the methanol gasoline can be increased due to the adoption of the yeast fatty acid, and then, the air resistance rate is reduced obviously; and the effect of adjusting the boiling range and saturated vapor pressure is very obvious, and the problem of high-temperature air resistance of the methanol gasoline is solved effectively.

Description

technical field [0001] The invention relates to the field of alcohol substitute fuels, in particular to an antiknock and air resistance reducing agent which is mainly based on biomass energy and can be blended with bioalcohols in a high proportion and a preparation method thereof. Background technique [0002] For a long time, gasoline and diesel have been the main fuels for various types of motor vehicles. This usage pattern is increasingly restricted by serious environmental pollution and increasingly scarce resources. In order to improve this dilemma, a variety of energy alternatives have been adopted at home and abroad. However, if these alternatives are to be popularized on a large scale, there are serious defects. In recent years, as the international oil price continues to hover at a high level, the promotion, application and research process of alternative alcohol-ether fuels at home and abroad have been accelerated. According to the implementation of the strategic ...
