Description

A kind of preparation method of clean diesel

Technical field

The invention provides a kind of method of raw material, especially a kind of preparation method of clean diesel.

Background technology

Diesel oil is the required fuel of diesel motor work.At present, oil is adopted fewer and fewer, and oil price is increasingly high

At present, generally using gasoline, diesel oil, oil liquefied gas in the world all is to be formed by petroleum refining, is referred to as fossil fuel.

According to International Energy Agency prediction, the time limit exploited of the global petrochemical industry class energy is respectively oil 39 years, Sweet natural gas 60 years, coal 211 years.How of short duration this is in the long process of human history! The petroleum resources that hundreds of thousands of year could form; Adopt one barrel few one barrel, prospective oil is gradually exhausted, the oil production quantity not sufficient; Cause the situation that global fuel feeding is nervous, oil price soars all the way, and the rise of the oil price that causes because of the petroleum resources shortage will be irreversible inexorable trend! Oil is the mover of modern economy development, and oil price is soaring, must affect Sweet natural gas and coal to go up.From 2002 till now, main fuel prices such as China's diesel oil, gasoline, Sweet natural gas, raw coal all turned over one turn over many.The China's oil imbalance between supply and demand becomes increasingly conspicuous, and China is the poor relatively countries of petroleum resources, is again oil consumption big country, and reserves are merely the whole world 2%.At present, the explored prospective oil of China is 23.8 hundred million tons, and " by 1.8 hundred million tons to 2.0 hundred million tons speed calculation of annual produce oil, 23.8 hundred million tons oil reserve will be exhausted after 14 years ".The petroleum demand that China is full of explosive power is regarded as the key factor that international oil price over the past two years rises sharply always, has become the second-biggest-in-the-world oil consuming countries and second largest oil importers (being only second to the U.S.) at present.China's oil demand year increases by 5.77%, and average annual growth of domestic petroleum production is merely 1.67%.Predict China's stone consumption in 2010 and will reach 300,000,000 tons, the oil breach reaches more than 1.6 hundred million tons.Because domestic petroleum output can not increase substantially, newly-increased petroleum demand is with complete dependence on import.Oil shortage direct threats China economy, political and military safety.Analysis expert points out, when a national petroleum import surpasses 5,000 ten thousand ton hours, the oil price of world market changes will influence this national national economy operation; After import volume surpasses 100,000,000 tons, just must consider to take diplomacy, economy, military measure to guarantee oil supply safety.

Oil is that modern society uses basic energy resource the most widely, and the title of modern society's " economic blood " is arranged.Oil relies on import not only will consume a large amount of foreign exchanges in a large number, and sustainable economic development of serious threat China and national security.Crude resources is deficient, and supplydemand relationship is unbalance, and gasoline, diesel-fuel price climb up and up, and has become " bottleneck " that hinder Chinese Economy Development.Facts of life also is breeding huge business opportunity simultaneously!

Diesel oil mainly refines through crude oil and obtains, and raw material sources are more single; Cost is high, and incomplete combustion, and exhaust emissions contains hazardous substance many; Environment is caused very big pollution.Also have in the prior art and adopt junked tire or plastics refinery to produce diesel oil, but cetane value is low, impurity is many, in use can burn to form porous shape settling, shorten engine life greatly, and production and processing technology is complicated.Production cost is high.

Summary of the invention
