In order to meet the needs of modern industry, people retort wood or pulverized coal to make carbon with high adsorption capacity and certain shape. This carbon is early Activated carbon 。 Later, many kinds of activated carbon were developed, and coconut shell activated carbon was one of them.

    Activated carbon It is a product with carbon as the main component. It has been found for a long time that activated carbon can absorb some gases and remove the odor in sewage. It can be used as a clarifier, as a decolorant in sugar industry, etc. It can not only be used for various water purification machines, but also for solution extraction, gas mask filter, etc. In addition to paraffin and heavy oil in the petroleum industry, the factory will also get a considerable amount of light oil. In the synthetic tail gas, most of this light oil is recovered by activated carbon adsorption, Activated carbon is often used in oil processing plants to recover light oil from natural gas and processed gas to increase the output of light oil.

Activated carbon is often used in petroleum synthesis plants to remove sulfides from gas. For example, too many sulfides in gas will poison the synthesis catalyst and lose its activity. However, active carbon can play a very good role in desulfurization. It is easy to see that activated carbon plays an important role in the petroleum industry
