Description
Technical field
The invention belongs to refining art, in the preparation method of a kind of recycle oil and the pickling in preparation process thereof
Mediating recipe.
Background technology
Along with society's high speed development, various energy demands increase day by day, and the demand particularly with power sources such as oil is huge
Greatly.Along with the exploitation energetically of the mankind, resource is the deficientest, and meanwhile, along with the mankind's continuous pollution to environment, environmental protection also becomes
The problem of whole mankind's facing.Along with the development of science and technology, kitchen excess oil (being commonly called as waste oil), used oil, waste plastics etc. are smelted
Regeneration recovery technology is increasingly mature, and energy-conserving and environment-protective are advocated energetically.
Along with developing rapidly of plastics industry, the application of plastic is wider, has penetrated into each of national economy
In individual field and daily life, plastics have the feature such as thermal insulation, corrosion resistance, himself have the special feature that and can add
To utilize, but when waste or used plastics processes, above-mentioned characteristic can hinder plastics, the most perishable causes environment to be polluted.
