Abstract
The invention relates to an energy technique, and the names of the products are the preparation and the usage of a gasoline octane number enhancer. The technique mainly considers the conditions that the price of most of the gasoline octane number enhancers commercially available in China is high and the markets are in urgent need of a number of gasoline octane number enhancers with low price and good service performance. The gasoline octane number enhancer is prepared by adopting absolute methanol or synthetic ethanol or fermented ethanol with wide resources and low price in China, adding a cosolvent (a mid-carbon alcohol or ether product), and simultaneously adding a small quantity of antioxidant and corrosion inhibitor. The used main raw material comprises the following high octane number products in portion by weight: 75 to 85 portions of the absolute methanol or synthetic ethanol or fermented ethanol, 15 to 25 portions of the cosolvent, 2 portions of the antioxidant, and 1 portionof the corrosion inhibitor. 5 to 20 percent of the gasoline octane number enhancer is added into gasoline in percentage by volume, and the octane number can be improved by 1 to 15 units. By using thegasoline octane number enhancer, the antiknock performance of the gasoline can be improved, the cost of the gasoline can be reduced, the fuel can be saved, and the pollutant discharge can be reduced.
Description
Technical field
The present invention is an energy technology, and its product is mainly used in the raising gasoline octane rating, improves the capability of antidetonance, energy-saving and emission-reduction.
Background technology
Current, the most of price height of China's marketable gasolines octane enhancer, adding back gasoline cost increases, and the dealer is dissatisfied, and burden for users increases the weight of.Therefore, this series products dull sale, some prices of market in urgent need are low, the gasoline octane rating rising agent that use properties is good.
Summary of the invention
The present invention makes full use of wide, the cheap anhydrous methanol of china natural resources or synthesizing alcohol or fermenting alcohol, adds the solubility promoter (middle carbon alcohol or ether product) that the chemical plant produces, and adds a spot of antioxygen simultaneously, the anti-corrosion additive allotment forms.Used main raw material is the high-octane rating product: the methyl alcohol research octane number (RON) reaches 106～112, and motor-method octane number reaches 90～92; The ethanol research octane number (RON) reaches 110, and motor-method octane number reaches 90.Ether product methyl tertiary butyl ether research octane number (RON) reaches 120, and motor-method octane number reaches 100; The Ethyl Tertisry Butyl Ether research octane number (RON) reaches 120, and motor-method octane number reaches 104.Middle carbon alcohol (C3～C9 n-alkanol or isomery alcohol) also is the high-octane rating product, reaches 99.6 as the propyl carbinol research octane number (RON), and the sec-butyl alcohol research octane number (RON) reaches 110, and the isopropylcarbinol research octane number (RON) reaches 107.The oxidation inhibitor 2,6 ditertiary butyl p cresol, the anti-corrosion additive benzotriazole.According to gasoline performance and storage cycle, per-cent is by volume produced in the allotment of gasoline octane rating rising agent: anhydrous methanol or synthesizing alcohol or fermenting alcohol 75-85 part, and solubility promoter 15-25 part, 2 parts in oxidation inhibitor, 1 part of effect of anti-corrosion additive is better.This gasoline octane rating rising agent joins in No. 90 unleaded gasoline for vehicle of GB, No. 93 unleaded gasoline for vehicle, No. 97 unleaded gasoline for vehicle or straight-run spirit (petroleum naphtha), catalytically cracked gasoline, gasoline alkylate and the catalytic reforming gasoline, all can improve the octane value of this oil product.In the gasoline by volume per-cent add this gasoline octane rating rising agent 5～20%, its octane value can improve 1～15 unit.Use this gasoline octane rating rising agent, can improve the capability of antidetonance of gasoline, reduce the cost of gasoline, have no side effect, fuel economy reduces pollutant emission.
Embodiment
Consult with national environmental protection portion, National Development and Reform Committee and relevant department of China Petrochemical Industry, wish to obtain the support of government department and oil major company, apply in the whole nation.Select the large user to try out, progressively promote the use of.
Claims (1)
- The allotment of gasoline octane rating rising agent is characterized in that by following raw material by volume formulated: anhydrous methanol or synthesizing alcohol or fermenting alcohol 75%-85%, solubility promoter 15%-25%, oxidation and corrosion inhibitor 3%.
