Abstract
The invention discloses a decoloring and deodorizing method of pyrolysis oil of waste tyres, and relates to a method of preparing pyrolysis oil. The method comprises the following steps: first, pre-treating the pyrolysis oil of waste tyres; them, mixing the pyrolysis oil with an adsorbent in proportion; heating the mixture to a certain temperature, and continuously stirring for a certain time at the temperature; then, entering into a filter device to separate the oil and the adsorbent; after regenerating filter residues, re-using the oil; distilling and refining the filtrate; and refining for a certain time to obtain a light component which is the product. The method can remove nitrides and non-ideal components such as other thiol and thioether in oil so as to improve the oxidizing stability of the oil. The pyrolysis oil treatment is simple in process, low in cost, easy to operate, simple in post-treatment and less in environmental pollution.
Description
technical field
The present invention relates to method prepared by cracked oil, particularly relate to the method for the decolouring of junked tire cracked oil, deodorization.
Background technology
Work the mischief to environment taking junked tire as the increase suddenly of main waste rubber goods at present, very important stage has been arrived in the recycling of junked tire and utilization.Industrial expansion needs increasing fuel and Chemicals, but global fixed resource is limited, so advocate recycling economy, realizes utilization of waste as resource, and it is very effective aspect addressing this problem that damaged tire cracking produces oil.Can be by waste tyre pyrolytic oil and petroleum crude oil are carried out to comparative study, realized comprehensive and reasonable and utilized the object of solid waste to seek a kind of reasonable approach.Some thermal treatment units are set up both at home and abroad, as adopted vulcanization bed or revolving brickkiln etc.
Although damaged tire cracking oil product out can directly use, because its color is crossed dark and gives an offensive smell, can bring inconvenience to user.Therefore can take decoloration and deodorization refining, remove sulphur hydrogen peculiar smell, and remove oxidation sediment, colloid, makes pitch black, muddy oil product become as clear as crystal, improves oil product outward appearance, transparency, purity, reaches higher use standard, improves economic worth.
At present, the main method of processing damaged tire cracked oil has hydrofining, acid-alkali refining and quadric catalysis refining, wherein these several refining losses that all can nearly 10%, because the sulfide wherein containing mainly exists with sulphur, hydrogen sulfide, mercaptan, thioether, these sulphur are all called active sulphur, wherein mercaptan accounts for 60% left and right, and in quadric catalysis cracking, mercaptan also can make poisoning of catalyst, affects refining effect.
Summary of the invention
The object of the invention is to propose a kind of method of junked tire cracked oil decolouring, deodorization, this law processing cracked oil technique is simple, cost is low, easy to operate, last handling process is easy, environmental pollution is little.
The object of the invention is to be achieved through the following technical solutions:
The method of the decolouring of junked tire cracked oil, deodorization, the method comprises following process:
First cracked oil is carried out to pre-treatment, then cracked oil and sorbent material are mixed in proportion, mixture heating, and at this temperature continuously stirring, then enter filtration unit, oil product is separated with sorbent material, after filter residue regeneration, can reuse, filtrate is distilled refining, gets light constituent and be product after refining.
Described junked tire cracked oil decolouring, the method for deodorization, its temperature of reaction is 30-100 DEG C.
Described junked tire cracked oil decolouring, the method for deodorization, its reaction times is 10 minutes-150 minutes.
Advantage of the present invention and effect are:
The sorbent used method for refining of the present invention, in decolouring, deodorization, does not need High Temperature High Pressure, has reduced the requirement to equipment intensity, and equipment is simple, cost is low, easy to operate, last handling process is easy, environmental pollution is little, better economic benefit.
