Abstract

The invention belongs to the technical field of petroleum chemical industry, and particularly relates to a tire pyrolysis oil fraction fixed bed hydro-upgrading catalysis process. The process includes a reaction device formed by serially connecting first, second and third reactors and used for upgrading of raw material oil. The process has the advantages that gasoline-diesel products higher in added value can be produced after fractionation, so that utilization value of tire pyrolysis oil is increased obviously, and bigger economic benefit and environmental benefit in the process of tire pyrolysis are realized; the process is simple in procedure, low in investment cost and conducive to realizing small-scale production.

Description

technical field [0001] The invention belongs to the technical field of petrochemical industry, in particular to a fixed-bed hydrogenation and upgrading catalytic process for tire cracking oil fractions. Background technique [0002] With the continuous development of the automobile industry, the demand for rubber products such as tires is also increasing. At the same time, the generation of waste tires is also increasing sharply. In 2009, my country’s production of tires consumed rubber accounted for about 70% of the country’s total consumption of rubber resources, and the annual waste tires produced weighed about 8.6 million tons. If all of them can be recycled and reused, it is equivalent to my country’s 5-year natural rubber output. As of 2015, the production of waste tires in my country has reached 11 million tons. From the perspective of environmental protection and resource utilization maximization, compared with the current disposal methods of waste tires such as lan...
