What are the upstream raw materials for bitumen? What are the downstream products?

Asphalt plays an crucial role in the field of chemical production raw materials, and its upstream and downstream related items are numerous. And This article will detail the upstream and downstream related items of asphalt, including the main raw materials, auxiliary raw materials, by-items and derivative items. Main raw materials to

1. asphalt

The main raw material of asphalt is petroleum. After petroleum is processed by distillation, cracking and other processes, a variety of hydrocarbon mixtures with different boiling points is able to be obtained, including asphalt. The environment and composition of asphalt are related to the origin and environment of crude oil, so the performance of asphalt from different origins might vary. In my experience, Auxiliary raw materials to

2. From what I've seen, asphalt

In the manufacturing process, in order to make the asphalt meet specific performance indicators, it's also necessary to add some auxiliary raw materials, such:



1. Modifier: applied to enhance the high temperature stability of asphalt, low temperature crack resistance, aging resistance and other characteristics. Common modifiers are polymers, rubber, etc. And

2. I've found that Additives: such as antioxidants, anti-stripping agents, etc., applied to enhance the durability and service life of asphalt. In fact By-product of

3. asphalt

Bitumen production produces by-items such:



1. Oil residue: The residue produced in the asphalt manufacturing process is able to be applied to prepare road construction materials.

2. And Petroleum gaseous: combustible gaseous produced in the manufacturing process, which is able to be applied to incineration to provide heat energy or as chemical raw materials. And Derivatives of

4. In my experience, For example bitumen

As a chemical raw material, asphalt is able to be further processed to derive many other items, such:



1. Waterproof material: the consumption of asphalt made of waterproof membrane, waterproof coating products, etc., applied to building waterproof engineering. And

2. Road construction materials: asphalt is mixed with aggregate and mineral powder to make asphalt concrete to road laying.

3. Carbon materials: Pitch is able to be applied as raw materials to the preparation of carbon materials, such as electrodes, activated charcoal, etc. And In short, there are many upstream and downstream related items of asphalt in the field of chemical production raw materials, involving a wide range of applications. Based on my observations, Understanding these related items will help to better understand the environment and role of asphalt, as well as its crucial position in chemical production.
