To want coal tar wash oil to become a diesel component, first of all to solve the problem of decolorization and deodorization, if this problem is solved, wash oil as a blending component of diesel has great hope. Because its fraction is in the range of diesel fuel, although the density is large, it is difficult to catch fire, easy to oxidize, unstable, the gum is large, the acidity is large, and the engine is seriously corroded, but if the color of wash oil can be decolorized to close to the national standard Diesel chroma, many of the above problems are solved. China's coal tar wash oil resources are rich, but due to the low deep processing capacity of China's coking products, the current chemical use value of wash oil and naphthalene oil after denaphthalene removal is not large, most of them are from one-third to one-half of the diesel price. Price export. If this part of the product can be developed into diesel fuel, not only can it obtain greater social benefits, but also economic benefits will be very obvious.
