Abstract
The invention discloses a catalyst for pyrolyzing waste rubber and waste plastics to refine oil, which relates to the oil refining technology. The catalyst is formed by mixing the following materials in percentage by weight: 30 to 60 percent of tricalcium silicate, 15 to 27 percent of dicalcium silicate, 7 to 15 percent of tricalcium aluminate, 10 to 18 percent of celite, 20 to 30 percent of calcium oxide, 10 to 15 percent of calcium carbonate, 2 to 5 percent of sodium oxide and 1 to 3 percent of potassium oxide, and then milling the mixture with a ball mill pulverizer to 200 meshes. The waste rubber and the waste plastics are directly used as raw materials and mixed with the catalyst in a weight ratio of 100:1-10. The prior process and general equipment are adopted; the waste rubber and the waste plastics are directly used; the catalyst materials are easily obtained, the manufacture is simple and the cost is low; the reaction temperature is low and the reaction time is short; the oil yield is improved by 10 to 15 percent; and the crude oil has the characteristics of more alkanes, less other hydrocarbons and the like.
Description
One, technical field
The present invention relates to utilize scrap rubber, waste plastics refining fuel oil technology, the catalyst that especially a kind of scrap rubber, waste plastic oil-refining cracking are used.
Two, background technology
Scrap rubber, waste plastics under normal circumstances are difficult to natural degradation, and " white pollution " problem also becomes more and more serious.Utilize scrap rubber, cracking waste plastics to produce the mode that fuel oil is a kind of regeneration.Adopt after scrap rubber, the waste plastics fragmentation at present, put into the cracking reaction still with catalyst and carry out cracking reaction, resultant gas phase mixture matter, by the condensation heat sink, the processing of lowering the temperature, and then carry out oily-water seperating equipment, and obtain thick oil, waste water and combustion gas.Device therefor is a common apparatus, as horizontal or vertical cracking reaction still, condensation heat sink, oil-water-gas separating device etc.The general used catalyst of crude oil pyrolysis technology that uses is as HY, Ni-REY, HZSM-5 equimolecular sieve catalyst, because the catalytic reforming of cracking waste plastics product and crude oil pyrolysis product has similarity.Yet oil composition than the waste plastics complexity many, thereby with the modified catalyst catalysis cracking waste plastics gas of crude oil pyrolysis can produce such as catalyst poisoning, reaction not thoroughly, lysis efficiency is low and variety of problems such as the difficult life of catalyst, cost height.
On April 16th, 2008, publication number is CN101161783A, " a kind of environment-friendly type oil refining method and use the oil refining apparatus of this method " patented technology is disclosed, the waste materials containing carbon that to handle through fragmentation is packed into highly basic in the reactor, heating makes its temperature rise to 350 ℃-380 ℃, carry out catalytic cracking reaction, finish to stop heating to reaction; The mixed vapour that produces in the course of reaction enters into branch gas bag release of pressure, enter then and cool to 10 ℃-40 ℃ in the oil duct condenser, the liquid that obtains enters and carries out water-oil separating in the oil water separator, and gas enters in the gas burner and burns, and the ash-laden gas that burning produces is discharged after purifying.Use highly basic as catalyst.
Three, summary of the invention
The objective of the invention is to utilize existing disclosed scrap rubber, oil refining process of waste plastic and common apparatus, is that integral body need not chopping or pulverize to be raw material to scrap rubber, waste plastics in the oil refining cracking reaction, uses a kind of mixed catalyst.
Technical scheme that purpose of the present invention adopts is that catalyst comprises tricalcium silicate, dicalcium silicate, tricalcium aluminate, tetra calcium aluminoferrite, calcium oxide, calcium carbonate, sodium oxide molybdena, potassium oxide, it is characterized in that:
A. described catalyst is by weight with tricalcium silicate 30-60, dicalcium silicate 15-37, tricalcium aluminate 7-15, tetra calcium aluminoferrite 10-18, calcium oxide 20-30, calcium carbonate 10-15, sodium oxide molybdena 2-5, potassium oxide 1-3, mixes after ball mill pulverizer is crushed to 200 orders mixes;
B. be raw material directly with scrap rubber, waste plastics, with the mixed catalyst weight ratio be 100: 1-10.
The present invention adopts existing technology and common apparatus; Directly utilize scrap rubber, waste plastics; Catalyst material is easy to get, and makes simply, and cost is low; Reaction temperature is not high, the time short; Improve oil yield 10-15%; Characteristics such as alkane is many in the thick oil, and other hydrocarbon is few.
Four, the specific embodiment
Further specify the present invention below in conjunction with an embodiment.
By weight tricalcium silicate 45, dicalcium silicate 25, tricalcium aluminate 11, tetra calcium aluminoferrite 14, calcium oxide 25, calcium carbonate 12, sodium oxide molybdena 3.5, potassium oxide 2, mixing is crushed to 200 orders through ball mill pulverizer and forms, be positioned in the lump in the vertical cracking reaction still with the ratio of waste plastics by weight 2.5: 100, heat up 400 ℃, 4 hours time was carried out cracking reaction, obtain gas phase mixture matter, by condensation heat sink and oil-water-gas separating device, obtain the thick oil of product, waste water, product combustion gas.
