Features: 1. The definition of the term, also known as
Modified pitch is in temperature asphalt for the production of raw materials. Temperature in the ordinary asphalt benzene insoluble in the sub-BI is about 18%, quinoline insoluble points QI 6 percent. When the heat treatment of such asphalt, the asphalt in the aromatic elements in the process of condensation heat generated hydrogen, methane and water. At the same time some asphalt ¦Â resin part of the Central Plains into the second ¦Á resin, a part of benzene dissolved into ¦Â resin, ¦Á component growth, an increase of bonding, asphalt has been modified. This asphalt known as the Modified pitch.
2. The terms of the characters, briefing.
Modified pitch black at room temperature for the solid, softening point to 110 ℃.
3. The product processing cases
Production of heat-modified pitch is in temperature asphalt as raw materials, used for mixing with the pump into the reactor, after heated reaction, precipitation small molecules of gas, is the kettle liquid asphalt electrode.
Modification of heavy residual oil refining integrated production process modified pitch, softening point can be produced for around 80 ℃, ¦Â resin up to 23 percent or more of any class modified pitch, the yield of high-heat than 10 percent. This method is to dehydration in the tar in the reactor pressure to 0.5 ~ 2 ***, heated to 320 ~ 370 ℃, maintain 5 ~ 20 h, so that useful component of tar, particularly heavy oil component, and the low boiling point of instability heterocyclic Components in the reactor in the polymerization into asphaltene to get the best quality of the modified pitch.
