Embodiment 1

[0018] Add 15 grams of polyoxymethylene dimethyl ether, 100 grams of diesel oil and 1 gram of fatty acid, 2 grams of ethyl nitrate, 5 grams of polyethylene-vinyl acetate, 2 grams of butanol and 0.3 grams of isonitrate in a stirred reactor at 2800 rpm. Octyl esters. Mix the above-mentioned substances evenly at room temperature, stir at 2800 rpm for 30 minutes, and then let it stand for 8-10 hours. After the liquid is clarified, it can be filled into cans.

Embodiment 2

[0020] Add 30 grams of polyoxymethylene dimethyl ether, 80 grams of diesel oil and 2 grams of fatty acid, 5 grams of ethyl nitrate, 3 grams of polyethylene-vinyl acetate, 1 gram of isoamyl alcohol and 0.5 grams of nitric acid in a stirred reactor at 2800 rpm Isooctyl. Mix the above-mentioned substances evenly at room temperature, stir at 2800 rpm for 30 minutes, and then let it stand for 8-10 hours. After the liquid is clarified, it can be filled into cans.

Embodiment 3

[0022] Add 15 grams of polyoxymethylene dimethyl ether, 5 grams of methylal, 80 grams of diesel oil and 1 gram of alkenyl succinimide, 2 grams of amyl nitrate, 3 grams of ethylene-acrylic acid iso butyl ester, 1 gram of isobutanol and 0.1 gram of isooctyl nitrate. Mix the above substances evenly at room temperature, stir at 2800 rpm and then let it stand for 8-10 hours. After the liquid is clarified, it can be filled into cans.

Abstract

The invention relates to a method for preparing novel clean synthetic diesel oil and mainly solves the problems that the conventional diesel oil is low in cetane number and is combusted insufficiently in an engine, and a large amount of solid pollutant, COx and NOx are discharged. The method mainly comprises the following steps of: uniformly mixing 5 to 30 mass percent of diesel oil substitute component, 5 to 30 mass percent of additive and 40 to 90 mass percent of diesel oil at normal temperature, standing for 8 to 10 hours, and after liquid is clarified, canning to obtain the novel clean synthetic diesel. The diesel oil substitute component is polyformaldehyde dimethyl ether, methylal or mixture of polyformaldehyde dimethyl ether and methylal in any ratio. By the method, the combustion efficiency of the synthetic diesel oil is improved, the discharge of free carbon and harmful gas is reduced, the quality of the synthetic diesel oil is improved, cost is reduced, a novel way from coal to oils is developed, and the method has good social and economic benefit. The novel clean synthetic diesel oil can be used independently and can also be mixed with petroleum diesel oil to be used, and the engine is not needed to be changed.

Description

technical field [0001] The invention relates to a preparation method of a novel clean synthetic diesel oil, which belongs to the technical field of petrochemical industry. Background technique [0002] my country is a country poor in oil and gas, but relatively rich in coal resources. As of 2011, my country's remaining recoverable oil reserves were less than 2 billion tons. According to statistics in 2006, my country's coal, natural gas, and oil reserve-production ratios were 48 years, 41.8 years, and 12.1 years, respectively. In 2011, the oil import volume has reached 252.5 million tons, and the dependence on foreign countries has reached 55.2%. From the perspective of resource endowment and consumption structure, coal is the most important and reliable primary energy in the medium and long term in my country, and its position in my country's industrial development is irreplaceable. In 2011, China's coal output exceeded 3.5 billion tons, making it the world's largest coa...
