Abstract
The method for preparing petroleum product by using waste plastics includes the following steps: squeezing waste plastics into dissolving tank; adding hydrocarbon oil according to the ratio of 1:4; keeping temp. at 160 deg. C-250 deg. C; pumping the above-mentioned material into pipe-still; heating to 450 deg. C, then feeding the above-mentioned material into cracking tank so as to obtain gaseous organic hydrocarbon; by catalytic cracking and molecular reformation and feeding one into fractionating tower so as to can obtain liquiefied petroleum gas, gasoline, diesel oil and kerosene from different positions of said fractionating tower. Its technological process is reasonable, and its product recovery ratio is high, and its total recovery is above 70%.
Description
Along with plastic waste is serious day by day to the pollution of environment, countries in the world are more and more paid attention to the recycling of plastic waste, and more to the recovery and Utilization of Waste Plastics at present just material reuse of China is about to the simple and easy regeneration of plastic waste and makes plastic raw materials.Though the plastics oiling technology is also had some researchs, but because Technology is simple, generally all be plastic waste to be carried out cracking with the direct-fired method of reactor, because plastics cracking temperature is higher than 350C, therefore reactor very easily burns, and the interruption production of need one still one still, it is longer that each still adds the thermally splitting time, and heat energy utilization is very uneconomical.Therefore, can not form suitability for industrialized production.
The objective of the invention is to: provide a kind of plastic waste oiling method of not direct heating reactor, but its continuous production, self-skimming, assurance oil quality are realized large-scale industrial production.
The present invention is achieved in that it comprises and dissolves, cracking, the purification several steps is squeezed into plastic waste and dissolves in the groove, adds hydrocarbon ils in 1～4 times ratio, temperature is between 160C～250C, behind 450C, enter the cracking groove through being pumped into the tube furnace internal heating again, obtain the organic hydrocarbon of gaseous state, reform through catalytic cracking and molecule, send into separation column, can obtain liquefied petroleum gas (LPG), gasoline, diesel oil and kerosene from the different sites of separation column.
The present invention compared with prior art, it is reasonable to have processing method, the product recovery rate height can effectively solve advantages such as " white pollution " problem.Its various fuel oil product total yields are more than 70%, also recyclable carbon element and liquefied gas, and can realize large-scale industrial production, have very high economic benefit and social benefit.
Embodiments of the invention: get plastic waste and after broken, cleaning, drying, be squeezed in the dissolving tank for 100 kilograms with charging machine, add 200 kilograms of diesel oil being preheating to 250C simultaneously, plastic waste dissolved and finishes in about 10 minutes, pump into the tube furnace internal heating and carry out thermally splitting to 450C, enter gasification in the catalytic cracking groove then, maintain the temperature at 380C, after reforming, synthetic zeolite catalysts cracking enters separation column automatically, tower top temperature is controlled at 200C, overhead gas is cooled to 30C and gets 37.5 kilograms in No. 70 gasoline, 235.4 kilograms of side line distillate diesel fuels.Lower curtate at the catalytic cracking groove is removed 8.7 kilograms of carbon slags, can produce carbon element.The not noncondensing gas that overhead condenser is emitted is compressed to make 8 kilograms of liquefied gas behind 1.8MP.Go into
