Full range analysis solution for tire oil
More and more waste tires are produced, but they cannot be dealt with in time and appropriately, resulting in a kind of "black pollution". Thermal cracking of waste tire represents the development direction of recycling.
What are the applications of hot cracking oil obtained from thermal cracking of waste tires?
Waste tire pyrolysis oil is directly burned as fuel. Because the pyrolysis oil is a wide range oil, it is cut into light fraction, medium fraction and heavy fraction after distillation. Different processing schemes can be determined according to the characteristics of each fraction, so that the value of waste tire pyrolysis oil can be improved.
1) Light fraction (initial distillation point ~204 C)
The light fraction can be hydrorefined to remove sulfur and oxygen in the fraction to extract aromatics and limonene, and then further refined to obtain chemical products BTX and limonene. Limonene is used to clean circuit board. If it can be reasonably used, the added value of waste tire pyrolysis oil can be reasonably improved.
2) Intermediate fraction (204~350 C)
The middle fraction can be used as the blending component of low freezing point diesel oil after hydrotreating.
3) Heavy fractions (& GT; 350 C)
Heavy fractions can be used as fuel oil for diesel generators, engines, heavy machinery, boiler heating, etc. Asphalt can also be obtained in addition to this product. Asphalt can be used to pave roads, or it can be sent to asphalt plants for refining.
SH6536 automatic distillation tester adopts color LCD display screen, Chinese menu man-machine dialogue, wizard operation, the determination process is all automatic. In line with the national standard GB/T6536 "Distillation of petroleum products determination" and ASTMD 86 requirements design, using embedded computer, can automatically measure the initial distillation point of coal tar, 10%, 30%, 50%, 70%, 90% and dry point.
