Novel efficient and environment-friendly catalyst for waste tire oil regeneration

Abstract

The invention relates to a novel efficient and environment-friendly catalyst for waste tire oil regeneration. The novel efficient and environment-friendly catalyst comprises the following preparation steps: step 1, manufacturing a catalyst A; step 2, manufacturing a catalyst B; produced diesel oil is changed to be light yellow, the density reaches 0.86-0.88, the odor is basically eliminated, the values of hexadecane and octane in the diesel oil are high, C2 dry gas in pyrolysis gas is less, the liquid yield is up to above 80 percent, a pour-point depression effect is realized, and a pour-point can be controlled to be 0 to minus 20 DEG C. The catalyst has the benefits that the service life is long, about 800 tons of tire oil can be processed by one ton of catalyst and be regenerated for 2-3 times, the cost is improved by about 50 yuan / ton to 100 yuan / ton, complicated acid and alkali washing processes are omitted, the sales price is higher than 500-1000 yuan compared with that of oil produced without using the catalyst, the content of sulphur in the oil is low, the catalyst is taken as fuel and is used for directly burning tail gas, and the emission is up to standard, so that the environment-friendly and pollution-free standards are completely achieved.

Description

technical field [0001] The invention belongs to the technical field of energy regeneration and utilization, in particular to a novel high-efficiency and environment-friendly catalyst for regeneration of waste tire oil. Background technique [0002] Environmental pollution is a worldwide issue. Black pollution such as waste tires (waste rubber) has attracted more and more attention. Now this technology is attracting much attention abroad, and there are high calls for its introduction. At home, it has not been paid attention to, and people are satisfied with the rubber powder processing method and the current processing method. Recently, although relevant state departments have repeatedly emphasized the prohibition, the government must legislate to solve this problem. Strengthen the legislation on the treatment of black pollution, attach importance to high-tech treatment technologies, encourage the development and utilization of new technologies, give scientific research more...

Problems solved by technology

[0006] The problems faced by the development of the waste tire comprehensive utilization industry: First, most of the enterprises engaged in the comprehensive utilization of waste tires are small in scale, with backward equipment, and their comprehensive strength is not strong, especially the secondary pollution problem of recycled rubber enterprises has not been solved; It is weak and has not yet established a recycling system with standardized operation. It is difficult for enterprises with relatively high technical level to obtain the waste rubber resources needed for production. Third, product technology and quality standards are not perfect, resulting in uneven product quality and affecting Market development; Fourth, there is a general lack of technical research and development means and strength, and insufficient technological innovation capabilities

[0009] At present, our country mostly uses waste tires to refine oil with low investment and poor equipment. During the production process, a large amount of toxic and harmful smoke and gas will be generated, which will seriously pollute the air. The waste residue and waste oil produced during the production process will also seriously pollute the environment.

In addition, the oil produced by local oil refining is mostly a mixture of various oil bodies, and the oil quality is extremely poor, which is a great waste of resources
