Abstract
Production of diesel oil from waste lube oil is carried out by putting waste lube oil into distillation still, heat distilling, adding flokite 0.5-2wt% of lube oil into distilling tower as catalyst, controlling distilling temperature between 125-380degree, first distilling to obtain distilland, putting it into agitator, adding into commercial sulphuric acid1-1.5wt%, agitating for 2-3hrs, laying aside for 3-5hrs to obtain supernatant, putting it into agitator, adding into sodium hydrate 1-1.5wt% with concentration 25-30%, agitating for 2-3hrs and laying aside for 3-5hrs to obtain the final product. It's simple, has better recovery rate and no environmental pollution.
Description
(1) technical field
The present invention relates to a kind of method of producing diesel oil with waste lubricating oil.
(2) background technology
Existing waste lubricating oil (oil, all kinds of lubricating grease at the bottom of vapour, bavin machine oil, shafting oil, hydraulic efficiency oil, wear-resistant pressure oil, transformer oil, the ship storehouse) has only the not high lubricating oil of specification of quality that seldom partly is used for regenerating, and major part all abandons as waste material, the tool statistics, China has a few kiloton waste lubricating oils to produce every day, wherein, can't utilize more than 70%, promptly cause environmental pollution, also waste resource, still do not had method processing preferably at present.
(3) summary of the invention
The object of the present invention is to provide a kind of method of producing diesel oil with waste lubricating oil, this method not only can make full use of the resource of relieved machine oil, turns waste into wealth, and has improved problem of environmental pollution.
The technical scheme that adopts is:
Produce the method for diesel oil with waste lubricating oil, it is characterized in that this method is waste lubricating oil to be packed into to add thermal distillation in the still kettle earlier, in big still kettle, add the mordenite of waste lubricating oil weight 0.5-2% simultaneously as catalyzer, distillation temperature is controlled at 125-380 ℃ and finishes fore-running, the distillate that obtains is put into stirrer again, and the 1-1.5% industrial sulphuric acid that adds distillate weight stirs after 2-3 hour and left standstill 3-5 hour, getting supernatant liquor adds in the stirrer, the 1-1.5% industrial sulphuric acid that adds supernatant liquor weight again stirs after 2-3 hour and left standstill 3-5 hour, getting supernatant liquor adds in the stirrer, the 1-1.5% sodium hydroxide that adds supernatant liquor weight again, concentration sodium hydroxide is 25-30%, stir after 2-3 hour, left standstill 3-5 hour again, the gained supernatant liquor is the diesel oil that makes.
Production method of the present invention is simple, the rate of recovery is high, product meets national standard fully, has promptly solved the pollution of waste lubricating oil to environment, has solved the problem of waste lubricant oil regeneration again.
