In the petrochemical industry, light benzene and crude benzene are common products, they have important applications in many fields. However, many people are not clear about the difference between light benzene and crude benzene, and even confuse them. In order to help you better understand these two substances, next, we will introduce their differences in detail.

let's look at it by definition. Light benzene refers to more than 95% of benzene for benzene petrochemical products, its main composition is benzene and styrene. The crude benzene refers to the benzene content of benzene is 90% to 95% of the product, its main components are benzene and styrene. From the definition point of view, the difference between light benzene and crude benzene mainly lies in the content of benzene.

from the use point of view, light benzene and crude benzene are also different. Light benzene is usually used to produce chemical products such as phenol and o-xylene, while crude benzene is mainly used to produce products such as polystyrene (PS) and cyclohexane. It can be seen that light benzene and crude benzene have obvious differences in use, and they provide raw material support for different products.

again, from the production process, light benzene and crude benzene are also different. The production of light benzene needs to be obtained through the separation and purification process of benzene, while the crude benzene needs to be obtained through naphtha hydrocracking or benzene extraction process. Therefore, in the production process, light benzene and crude benzene are also different.

In general, the difference between light benzene and crude benzene is mainly reflected in three aspects: the difference in definition, the difference in use and the difference in production process. A deeper understanding of these differences will help us to better use and produce these two petrochemicals. I hope that through the introduction of this article, you can more clearly understand the difference between light benzene and crude benzene, and contribute to the development of the petrochemical industry.
