Problems solved by technology

At present, the domestic recycling rate of waste rubber and waste plastics is very low, which not only causes environmental pollution, but also causes a lot of waste of energy.
The existing method of manufacturing fuel oil from waste rubber and waste plastics is generally cracking method, but because rubber products contain stearic acid, anti-aging agent, accelerator, pine tar, sulfur, etc., the oil quality is poor and the odor is large

Abstract

The invention discloses a production method for producing fuel oil by waste rubber and waste plastics, and belongs to a process method for producing the fuel oil. The invention provides the energy-saving production method for producing the fuel oil by waste oil of petroleum products. The following technical schemes are adopted: the production method comprises the following steps: (1), crushing the waste rubber and the waste plastics, adding an oxidant, and stirring; (2), rising the temperature of raw oil to 150 DEG C, carrying out standing sedimentation, dehydration and impurity removal treatment, and then discharging separated water and impurities; (3), taking 5 parts by weight of a reductant; (4) adding an adsorbent and the reductant into the raw oil under a stirring condition with the ratio of the raw oil, the adsorbent and the reductant of 500:1:0.3; (5), placing the raw oil after being mixed with a catalyst into a reaction kettle, electrically heating to 100 DEG C-110 DEG C, and carrying out an atmospheric pressure catalytic cracking reaction; and (6), sending an oil product after condensation into a bleaching tower, and bleaching by granular hargil in the bleaching tower to obtain finished oil.

Description

technical field [0001] The invention belongs to a process for producing fuel oil. Background technique [0002] Rubber and plastic are widely used in industrial and civil products, but waste rubber and plastic products are difficult to deal with and will cause certain environmental pollution. With the increasing shortage of oil resources, people turn their attention to waste rubber and plastics, and make fuel oil through pyrolysis technology, turning waste rubber and waste plastics into treasures. At present, the recycling rate of waste rubber and waste plastics in China is very low, which not only causes environmental pollution, but also causes a lot of waste of energy. The existing method of producing fuel oil from waste rubber and waste plastics is generally cracking method, but because rubber products contain stearic acid, anti-aging agent, accelerator, pine tar, sulfur, etc., the oil quality is poor and the odor is large. Contents of the invention [0003] The prese...
