Description

Preparation method of catalyst for catalytic pyrolysis waste
Technical Field
The invention relates to a preparation method of a catalyst for catalytic pyrolysis waste, belonging to the field of catalyst preparation.
Background
The waste rubber is one of solid wastes, and mainly comprises waste rubber products, namely scrapped tires, manual tires, rubber tubes, adhesive tapes, industrial sundries and the like, and the other part of the waste rubber products are from leftover materials and waste products generated in the production process of rubber product factories.
The disposal of waste rubber is one of the serious problems faced by people today, in order to meet the requirements of continuously improving the material performance, the rubber is developed towards high strength, wear resistance and aging resistance, and meanwhile, the problem that the waste rubber cannot be naturally degraded for a long time is also caused, and a large amount of waste rubber causes black pollution which is more difficult to dispose than plastic pollution (white pollution), and millions of tons of waste rubber are produced every year worldwide.
The waste rubber contains various additives
(1) Sulfur is taken as a main material, and the sulfur dioxide is changed into sulfur dioxide to be discharged along with flue gas to form acid rain during regeneration;
(2) And (3) supplementing a filling agent: the high proportion of carbon black is as many as 52 carbon blacks used in rubber industry, the carbon black wraps rubber particles during cracking and gasification, the carbon black is insufficient during combustion, the oxygen consumption is high, and the high temperature of regenerated coke is more demanding on the tolerance of a catalyst carrier.
(3) Anti-aging agent, physical and chemical anti-aging agent: amines, ketoamines, aldamines, phenols, and the like.
(4) Vulcanization accelerators and accelerator aids: calcium oxide, magnesium oxide, zinc oxide, stearic acid, TMTD, DM, and the like.
(5) Foaming agent: sodium bicarbonate.
(6) Coloring agent: and (3) metals.
At present, the foreign solutions mainly include two methods, namely, waste rubber burns at high temperature, high pressure and high concentration oxygen to generate heat, and the method provides supplementary energy for factories needing steam, which has the disadvantages of large investment, unsafe and high cost. Secondly, the waste rubber is ground into powder by a physical method for recycling, and the defect that only the natural rubber part can be utilized and a large amount of secondary waste is still remained.
It has also been studied abroad that the polymer rubber containing polyisoprene is subjected to thermal decomposition to break the chain into small molecular petroleum gas and fuel oil, and the decomposed waste residue is changed into carbon black product, and the carbon black product is still in the test stage.
CN107391C discloses a method for producing gasoline, diesel and carbon black from waste tyre and its equipment, said method is characterized by that after the waste tyre is broken, it is fed into thermal cracking reactor, at the same time, nitrogen gas, water vapour and combustion waste gas are introduced as carrier gas, and heated to 370-500 deg.C, and retained for 5-20 min so as to obtain gasoline, light diesel and heavy diesel.
CN1869160a discloses a method for preparing fuel oil by catalytic cracking of junked tires, which uses a cracking catalyst barium titanium ore composite oxide.
At present, thermal cracking or catalytic cracking of waste rubber becomes a research hot spot, but basically still exists in a laboratory stage, and the problems of low yield, poor selectivity and the like exist, and a proper catalyst is needed to be selected to improve a cracking product.
