Abstract
The oil producing process with waste tyre includes the following steps: 1) washing waste polyethylene plastic, feeding into reactor and heating in hydrogen atmosphere in the temperature raising rate of 5-20 deg.c/min to temperature 200-700 deg.c and pressure 20-50 MPa; 2) maintaining the said temperature and pressure for 5-80 min while stirring; 3) cooling to room temperature in the temperature lowering rate of 1-20 deg.c/min; and 4) withdrawing oil and carbon black products from the reactor.
Description
Technical field the present invention relates to a kind of method of utilizing damaged tire system oil, especially comprises the method for utilizing damaged tire system oil of hydrogenation technique.
In the method for background technology damaged tire recycling, thermo-cracking is a method the most completely, and the report of this method is just arranged in the U.S. many years ago.Thermo-cracking can change into valuable cargo fully with damaged tire and be used, almost do not pollute for the second time, and be damaged tire ideal recovery and reuse modes.But this method is in confidential state abroad always.
Chinese patent CNl424380 number disclosed " a kind of method of damaged tire degraded system oil " patent (application number: 02158705.1), be the weight ratio 7-15 by water and damaged tire: 1 adds in the reactor, temperature rise rate with 10-15 ℃/min under nitrogen atmosphere makes temperature of reaction reach 380-500 ℃, after reaction pressure reaches 23-45Mpa, reacted 10-60 minute, be cooled to room temperature, the gas-liquid product separates; The liquid phase oil aqueous emulsion is muttered to extract with the tetrahydrochysene fluorine and is carried out oily water separation, isolate the tetrahydrochysene fluorine that contains solvend and add anhydrous Na #-[2 in muttering] SO#-[4] remove minor amount of water wherein, pass through again at normal pressure, evaporation and 0.2 normal atmosphere under the 60-70 ℃ of condition, after the vacuum-drying, obtain oil product under the 30-50 ℃ of condition.The present invention has to be provided oil product and carbon black and not to have the environmentally friendly technology that waste water does not have noxious gas emission; Speed of response is fast, and the residence time is short; Help the advantage that the industrialization continuous production processes realizes.The weak point of this patent is: add water, oily water separation, remove wherein minor amount of water, process such as drying, make whole process too complicated, waste time and energy, cost rises; Additive-free, make that the system oil efficient of damaged tire is lower.
Purpose of the present invention is exactly that a kind of simple to operate, system oily efficient high method of utilizing damaged tire system oil will be provided, and comprises hydrogenation technique, makes the oily process of whole system easier, the made oil of per unit damaged tire more.Summary of the invention in order to achieve the above object, 1), damaged tire is cleaned the back add in the reactor method of damaged tire system oil of utilizing provided by the invention comprises the following step:, temperature rise rate with 5～20 ℃/minute under nitrogen atmosphere makes reactor temperature reach 200～700 ℃, and pressure reaches 20～50Mpa; 2), under this temperature and pressure, kept 5～80 minutes, and constantly stir material in the reactor; 3), slowly cool to room temperature with 1～20 ℃/minute rate of temperature fall; 4), in reactor, take out oil product and carbon black.
The method of damaged tire system oil of utilizing provided by the invention has significant advantage: do not comprise and add the water conservancy project skill, it is easier to make oily process; Hydrogen, be additive be again catalyzer, the made oil of the unit's of making damaged tire more; The oily process of whole system is faster, and more economical with materials and energy consumption reduce cost greatly.
Step of the present invention is simple, need not description of drawings.
The invention belongs to application invention, its protection domain relates to all changes form recited above.
