Problems solved by technology

However, when the above-mentioned catalysts in the prior art are used to process plastic waste, there are disadvantages such as high processing temperature, large energy consumption, poor oxidation stability of the obtained product, high catalyst cost, and complicated preparation methods.
In addition, before the plastic waste is processed, it needs to be cleaned, and the coking in the reactor is serious

Embodiment 1

[0033] 150 grams of zeolite was boiled in 500 ml of 065N ammonium chloride solution for 5 hours, and then the chloride ions were washed away with clear water. 8 grams of potassium oxide, 8 grams of vanadium oxide, and 3.4 grams of phosphorus pentoxide were pulverized into powders with a particle size of 2 to 4 mm, and then mixed with 33 grams of pseudoboehmite powder. The compound obtained is mixed with 31 grams of sodium silicate sol (commercially available commodity), added water and adjusted to slurry, shaped into particles with a diameter of 5-6mm with a granulator, first treated at 400°C for 25 minutes, and then Calcined at 650°C for 3 hours to obtain the catalyst of the present invention.

Embodiment 2

[0035] 150 g zeolite, 5.5 g MoS 2 , 4.5 g NaNO 3 , 3.4 g CaCO 3 and 2.4 g Fe 3 o 4 Mixed, crushed into a powder with a particle size of 2 to 4 mm, and then mixed with 32 grams of pseudo-boehmite powder. Mix the obtained mixture with 56 grams of silicon solution, add water to make a slurry, use a granulator to form particles with a diameter of 5-6m, first treat at 400°C for 30 minutes, and then bake at 750°C for 2.5 hours, The catalyst of the present invention is obtained.

Embodiment 3

[0037] 150 grams of zeolite, 6 grams of MoS 2 , 7.5 grams of NaNO 3 , 4.5 g CaCO 3 and 2 g Fe 3 o 4 Mixed, crushed into a powder with a particle size of 2 to 4 mm, and then mixed with 32 grams of pseudo-boehmite powder. Mix the obtained mixture with 75 grams of silicon solution, add water to make a slurry, use a granulator to form particles with a diameter of 5-6mm, first treat at 400°C for 25 minutes, and then bake at 700°C for 3 hours, The catalyst of the present invention is obtained.

Abstract

A catalyst for preparing oil products from used plastics is prepared from zeolite, components A, B and M, Na, Ca and Fe through washing zeolite with the solution of ammonium oxide, proportionally mixing with others, adding alpha-AlO(OH) powder and sodium silicate, stirring, granulating and calcining at 350-750 deg.C. Its advantages are low cost, long service life, and high output rate and quality of resultant oil products.

Description

technical field [0001] The invention belongs to the category of catalysts, and in particular relates to a catalyst used in plastic waste oiling technology. Background technique [0002] With the rapid development of the plastic industry, plastic products are becoming more and more important in industrial production and people's daily life. It can be said that plastic products have penetrated into all areas of people's lives. The world's plastic production has exceeded 100 million tons per year, while waste plastic production is more than 70%. Since plastic waste can hardly be degraded naturally under natural conditions, more and more plastic waste seriously threatens the living environment of human beings. Solving the environmental pollution caused by plastic waste and recycling plastic waste is a very important issue. So far, various methods for processing plastic waste have been proposed. Generally, catalysts are used to catalyze and thermally crack plastic waste. For...
