YJ-DY Used Motor Oil Cracking Process For Diesel Production

1.Why We Re-refine Used Motor Oil to Diesel Fuel?
Oil lasts for thousands of years. Once it is refined and used in our vehicles only to be discarded 3,000 miles later, it is still in a form that will keep for many years. Motor oil mainly used in auto engines, transmissions, gear-boxes, turbine transmission devices etc. No matter what sizes of cars or vessels, the period and standard of replacement are explicitly stipulated(once a month).Calculating based on a medium or small scale city, all sorts of cars, farm vehicle, mechanic cars generate spent oil approx 1000T.Add to the leftovers from refineries, chemical plants, fertilizer plants, coking plants etc. The total quantity is stupendous huge. Disposal through burning or dumping is not only bring heavy environment pollution, but also cause a enormous waste of energy. No matter eyes on energy resource reuse or environmental protection, bringing huge economic benefit to producers, waste oil regeneration has very good prospect.
2.Feasibility Of Used Motor Oil Cracking
There are two ways to manage the spent lube oil, the first is recycle it into lube base oil, and another method is crack it in to fuel.The same technology however that distills motor oil from crude oil is essentially the same technology that distills used oil into diesel fuel. The process to re-refine used motor oil is easier than refining crude oil.
During processing, gasoline and diesel could be obtained through different distillation temperature ranges. 50-160℃ is gasoline fraction range, and 160-410℃ is diesel fraction range. After cracking and cooling, about 2-5%% liquid is gasoline . Approx 85-90% liquid is similar to diesel and able to meet the specification of -15# diesel. They’re able to be used as industrial or civil-use fuel, even power driven fuel. Motor oil is from a fraction after diesel in oil refining industry, they’re belong to the same petroleum family having different molecular weight, it is very feasible to produce diesel.



3. How to Crack Used Motor Into Diesel Fuel?
Oil can be used in many different products, and this is because of its composition of many different hydrocarbons of different sizes, which are individually useful in different ways due to their different properties. The purpose of a refinery is to separate and purify these different components. Most refinery products can be grouped into three classes: Light distillates (liquefied petroleum gas, naphtha, and gasoline), middle distillates (kerosene and diesel), and heavy distillates (fuel oil, lubricating oil, waxes, and tar). While all of these products are familiar to consumers, some of them may have gained fame under their refined forms.
Cracking is a petroleum refining process in which heavy-molecular weight hydrocarbons are broken up into light hydrocarbon molecules by the application of heat and pressure, with or without the use of catalysts, to derive a variety of fuel products. Cracking is one of the principal ways in which used oil is converted into useful fuels such as motor gasoline, diesel fuel and home heating oil.
Cracking breaks carbon-carbon bonds to turn heavier hydrocarbons into lighter ones. This can occur thermally (as occurs during the petroleum formation process beneath the earth) or through the action of a catalyst
