Abstract
The invention belongs to the diesel oil refining technology, especially a new technology for catalytically cracking light diesel fuel from waste motor oil. Currently, the drawbacks of the prior technology for refining the waste motor oil into diesel oil are that: the cetane number falls short of national standard and the chroma is deep and opaque, the recovery is low and the technology is complex. The new technology comprises the following steps: adding waste motor oil into a reaction kettle; adding a hone-made good catalyst accounting for 1/1000 of the weight of the waste motor oil; heating to 300-500 DEG C to make the waste motor oil catalytically crack, finally obtaining distillation product; putting the distillation product into a condenser, making the condensed liquid-sate light diesel oil and the tail gas through an oil-gas splitter, making the tail gas into a gas collector; split diesel oil flowing into a treatment tank, adding high efficiency treating agent with concentration of 5/10000 into the treatment tank, treating the diesel oil using a backflow spray head; finally layering and filtering the treated light diesel oil by an oil water splitter, namely the yellow transparent light diesel oil with flash point >55 DEG C is obtained, with recovery of higher 80%.
Description
Technical field
The invention belongs to the diesel oil refinement technique, particularly a kind of from used oil the novel process of catalytically cracking light diesel.
Background technology
Used oil is that outside contamination produces a large amount of colloids, thereby oxide compound reduces and even lost it answers the powerful depleted material that suffers to lubricating oil owing in use being subjected to.State Bureau of Environmental Protection has been classified used oil as 21 century at one of three big emphasis of environmental protection field major control, and make full use of regenerating waste oil reduction finished product machine oil, or used oil is refined into gasoline, diesel oil, can alleviate the China's oil shortage and the growing imbalance between supply and demand of demand, can promote environmental protection to turn waste into wealth again, create considerable economic, help the part crowd to shake off poverty and set out on the road to prosperity, be that country encourages the support project, prospect is very wide.In recent years, the annual growth of China's machine oil product consumption surpasses 5%, and by the end of the year 2008, national vehicle guaranteeding organic quantity surpasses 1.5 hundred million, and a year replacing used oil reaches about 6,000,000 tons.Whole nation ships that transport reaches 200,000, and big or small motor fishing vessel reaches 1,500,000, about about 8,000,000 tons of the used oil that domestic boats and ships change every year, and this numeral does not comprise that also other cities come the large-tonnage freighter at port.Only above-mentioned two item number certificates, the used oil that year is produced is just up to 1,500 ten thousand tons.Add the used oil that aircraft, train, various big machinery and organizational equipment produce, estimate that the used oil that the whole nation is produced adds up to 2500～3,000 ten thousand tons/year.The generation of external used oil is surprising especially, and conservative estimation will be above more than 200,000,000 tons.In general, can should be about 50% of consumption for the used oil amount that reclaims, yet the used oil rate of recovery is very low at present, the reclaimed lubricating oil product that returns usefulness every year only has less than 10%, a considerable amount of used oil flow to not clear, and wherein a part enters environment and pollutes.Though used oil also can be done fuel and use, during owing to the burning used oil, heat distributes little, can produce a large amount of dense smokes, and environment is had very big pollution, and to human body also harm to some extent, it is few to produce beneficial effect.
The shortcoming that at present used oil is refined into the diesel oil Technology is that cetane value does not reach GB, colourity is dark opaque, and the rate of recovery is low, and complex process.
Summary of the invention
It is simple that the object of the invention provides a kind of technology, and cetane value, colourity reach the GB requirement, and the high novel process of catalytically cracking light diesel from used oil of the rate of recovery.
Take technical scheme to be for reaching this purpose the present invention:
A kind of from used oil the novel process of catalytically cracking light diesel, comprise following processing step:
A inserts used oil in the reactor, is controlled by bivalve by opening for feed, during oil-feed, opens gate valve earlier, opens stopping valve again, makes used oil add in the reactor smoothly by petrol-feed pump;
The b catalyzer adds inlet by catalyzer and joins in the reactor, after used oil and effective catalyst adding all finish, and valve-off, the effective catalyst add-on is 1/1000 of a used oil weight;
C reacting by heating still makes used oil reach 300～500 ℃ of temperature, makes the used oil catalytic pyrolysis, obtains diesel oil distillate gas;
D diesel oil distillate gas is by the cut of distillation tower to cut control sensing devices control diesel oil, and solar oil cut gas enters condenser condenses by pipeline, and condensed liquid solar oil enters oil-gas separator and carries out gas-oil separation;
Tail gas after e separates enters the water seal gas extractor by water-and-oil separator and spark arrester carries out collection and confinement of gases;
F separates the liquid solar oil in back and enters treatment tank, adds 5/10000 effectively refining agent in the treatment tank, and carry out countercurrent mass transfer through the countercurrent spray device and make with extra care, layering, through oily water separation, by filtering, solar oil gets product;
