Problems solved by technology

However, since crude oil contains some macromolecular polymers, these components have an adverse effect on the combustion of bio-oil
On the one hand, these components will affect the atomization effect of the emulsion, and block the nozzle in severe cases. On the other hand, after a period of combustion, more carbon deposits will be generated on the nozzle, which will affect the next start of the engine
In addition, these components have a high density, and they are easy to settle and precipitate when emulsified with diesel oil, which affects the stability of the emulsion

Abstract

The invention provides a method for refining waste paperboard pyrolytic oil (waste paperboard oil for short), which comprises the following steps: 1. carrying out component extraction separation on waste paperboard oil by using ether as an extraction solvent, thereby obtaining an ether soluble substance; 2. impregnating in a sulfuric acid solution to support La<3+> by using SiO2 / TiO2 as a catalyst support, thereby obtaining a solid superstrong acid catalyst; 3. carrying out alcoholization reaction on the ether soluble substance, ethanol and solid superstrong acid catalyst in a reactor under enhanced pressure or atmospheric pressure, thereby obtaining a primary refined waste paperboard pyrolytic oil (primary refined oil for short); and 4. adding the primary refined oil and a vulcanized hydrogenation catalyst into a high-pressure reaction kettle, introducing hydrogen with a certain pressure, and heating to a certain temperature to carrying out hydrogenation reaction, thereby obtaining the refined waste paperboard pyrolytic oil (refined oil for short). The refined oil prepared by the method has high stability, and can be directly used in a diesel engine after being emulsified with diesel, thereby implementing high-quality utilization of waste paperboard pyrolytic oil.

Description

technical field [0001] The invention relates to the field of high-value utilization of solid waste, in particular to a method for refining waste cardboard pyrolysis oil. Background technique [0002] As China gradually shakes off poverty and becomes richer, people are producing more and more garbage in their daily lives. my country is one of the countries with the largest amount of garbage discharge in the world, accounting for more than 1 / 4 of the world's annual garbage output, and about 40% of the country's total garbage has not been treated centrally, forming a situation of "garbage surrounding the city". situation. Therefore, the reasonable disposal of solid waste has become an important issue that people have to face. [0003] As an effective method for treating solid waste, pyrolysis has the advantages of high product utilization value, simple pyrolysis device, and high energy conversion rate, and has wider application prospects than traditional treatment methods. Ho...
