Embodiment 1
[0038] Example 1 Preparation of Waste Stripping Liquid Distillation Residual Fuel Oil
[0039] First, the waste stripping liquid is distilled and recovered to obtain the waste stripping liquid distillation residue. The specific composition information of the residue is shown in Table 1 and Table 2; take 10kg, 40kg, 200kg, and 1000kg of waste stripping liquid distillation residue respectively, and use the waste stripping liquid distillation residue weight As a benchmark, add 2.95%, 3%, 4.5%, and 5% hydroquinone by weight to the waste stripping liquid distillation residue respectively, stir and mix to obtain waste stripping liquid distillation residue oils 1, 2, 3 and 4 Then, add 180# fuel oil of 4kg, 20kg, 60kg, 500kg respectively in the stripping liquid distillation residual oil 1,2,3 and 4, mix and obtain fuel oil 1,2,3 and 4.
Embodiment 2
[0040] Example 2 Test and Analysis of Anti-coking Ability
[0041]In this example, the distillation residue of the waste stripping liquid and the fuel oils 1, 2, 3 and 4 prepared in Example 1 are tested and analyzed for anti-coking ability. The test method is: take 100 g each of the fuel oils 1, 2, 3 and 4 Heating at 400°C for 3.5h, another group of equal parallel samples without heat treatment, respectively adding toluene as a solvent, suction filtration in a constant temperature filtration device, weighing the content of toluene insoluble matter on the filter paper, and the fuel provided by the invention The difference obtained from the content of toluene insoluble matter in the oil - the content of toluene insoluble matter in the fuel oil provided by the invention before heating is B. Take 100g each of the common No. 4 fuel oil ①, ②, ③ and ④ and heat at 400°C for 3.5h. Another group of parallel samples of equal amount is not heated, but toluene is added as a solvent, and su...

Abstract
The invention relates to the technical field of recovery of waste stripping liquid, in particular to a fuel oil produced from waste stripping liquid distillation residue and a production method thereof. The production method of the present invention for producing fuel oil with waste stripping liquid vacuum distillation residue comprises steps: waste stripping liquid distillation and recycling to obtain waste stripping liquid distillation residue; adding anti-coking agent to waste stripping liquid distillation residue, stirring and mixing to obtain Waste stripping liquid distillation residue oil; And add 180# fuel oil in stripping liquid distillation residue oil, mix to obtain No. 4 light and No. 4 fuel oils; Anti-coking agent is hydroquinone, with waste stripping liquid distillation residue weight being As a benchmark, the amount of hydroquinone is 3-5%. The waste stripping liquid distillation residue fuel oil produced by the method of the present invention has an excellent anti-coking ability, realizes the recovery, treatment and reuse of the waste stripping liquid distillation residue, is conducive to reducing costs, improving the secondary utilization efficiency of the waste stripping liquid, and relieving the environment load.
Description
technical field [0001] The invention relates to the technical field of recovery of waste stripping liquid, in particular to a fuel oil produced from waste stripping liquid distillation residue and a production method thereof. Background technique [0002] With the rapid development of the domestic electronics manufacturing industry and optoelectronic industry, the usage of photoresist stripper and other electronic chemicals has also increased greatly. Usually, there is a photoresist stripping process in the manufacturing process of printed circuit boards, liquid crystal display panels, and semiconductor integrated circuits. It is necessary to use a stripper to remove the photoresist coated on the microcircuit protection area as a mask. This During the stripping process, a large amount of stripping liquid waste will be generated. In addition to a small amount of polymer resin (or PR glue) and photosensitizer, the stripping liquid waste liquid is mostly organic components wit...
