Embodiment 1

[0021] First, according to the material formula and weight (%) ratio provided by the present invention, prepare various materials, coal tar 78.0, waste plastic packaging bag 12.0, auxiliary agent 8.0, catalyst 2.0, weigh various materials by percentage, high temperature 780kg of coal tar, 120kg of waste plastics, 80kg of additives, and 20kg of catalysts.

[0022] Next, the waste plastics are firstly pretreated; after that, the waste plastic packaging bags are crushed to a particle size of 2 cm, and mechanically granulated to a particle size of 0.3 cm; Pyrite ore is added to the agitator respectively, fully stirred for 6 minutes, then transferred to the reaction process, the reaction temperature is 360 ° C, the reaction pressure is 4.5 mpa, and the reaction time is 15 minutes; then, enter the distillation process, the temperature is 360 ° C, and the distilled liquid is analyzed The detection enters the blending process. According to the test results, the blending agent amyl nit...

Embodiment 2

[0026] According to the process method provided by the present invention, diesel oil is replaced by using 75% of medium-temperature coal tar, 13% of waste plastic film, 9% of auxiliary agent, and 3% of catalyst. Each material is weighed, 750kg of medium-temperature coal tar, 130kg of waste plastic film , auxiliary agent shale oil 90kg, catalyst natural pyrite ore 30kg; after waste plastics pretreatment, add coal tar, auxiliary agent, catalyst to the mixer respectively, stir fully for 7 minutes and then transfer to the reaction process, the reaction temperature is 380 ℃ , pressure 5.5mpa, time 30 minutes; Enter blending process, add amyl nitrate 2kg in the ratio of 0.2%, the technical parameter of other each process is all identical with embodiment 1.

Embodiment 3

[0028] Adopt low-temperature tar, weigh material by following component weight (%) proportioning, low-temperature tar 72%, 720kg, waste plastic bubble packaging bag 14%, 140kg, auxiliary agent heavy oil 10%, 100kg, catalyzer 4%, 40kg. Various materials enter the agitator, and after uniform stirring for 8 minutes, they are transferred to the reaction process. The reaction temperature is 400°C, the pressure is 6.5mpa, and the time is 40 minutes. The liquefied oil enters the blending process. According to the test results, 0.3% amyl nitrate is added. Be 3kg, other operation and technical condition are all with embodiment 1.

Abstract

The invention relates to a technique method, which utilizes coal tar base to prepare diesel oil for replacing, and comprises the following procedures: preprocessing, squashing, stirring, reacting, distilling, blending and filtering. The invention is characterized in that the component weight (%) is that coal tar 78-66, waste plastics 12-16, auxiliary agent 8-12 and catalyst 2-6, wherein the coal tar is one of high-temperature, middle-temperature and lower-temperature coal tar or gasifying tar or is the mixture, the auxiliary agent is dead oil or shale oil and the catalyst is pyrite stone. Thetechnique method comprises preparing waste plastics into granular objects with 0.3cm, and then throwing coal tar, auxiliary agent, catalyst and plastic particles into a blender, transferring to the procedures of reacting and distilling after stirring for 6-10 minutes, and producing substitute diesel through the blending procedure of liquefied oil. Raw material is easy to get, and equipment is standard petrochemical equipment, and the production cost is low. The technique method can be widely used on farm vehicles.

Description

technical field [0001] The invention relates to the field of energy, in particular to a process method of using coal tar and waste plastics as raw materials to produce diesel oil instead. Background technique [0002] With the rapid growth of my country's national economy, the development of the iron and steel industry is crucial, and metallurgical coke and foundry coke are important energy sources in production. Therefore, the development of the coal coke industry is an important part of the iron and steel industry. Therefore, high temperature Coal tar resources are increasing day by day, and there are quite a lot of coal gasification tar and medium and low temperature dry distillation tar. At present, coal tar is mainly used at home and abroad to extract phenolic resin, benzene, naphthalene, phenol, anthracene, and asphalt, while my country's processing capacity is only one-tenth of that of domestic coal tar. Contents of the invention [0003] The purpose of the present ...
