Application of coconut shell activated carbon in petroleum industry

As early as many years ago, in order to meet the needs of industry, people burned and activated wood or pulverized coal to obtain black carbon that was worthy of adsorption capacity and gave it a certain shape. activated carbon extracting gold This is the earliest activated carbon. Later activated carbon developed many types, coconut shell, nut shell, columnar, honeycomb, powder, spherical and other types of activated carbon.

Coconut shell activated carbon is widely used in modern industry. In addition to the enamel industry and water purification, it is also used in solution purification and gas mask filters. In the petroleum industry, coconut shell activated carbon is used in the recovery of light oil with lower boiling point and the desulfurization of coal gas.

For example, in the process of petroleum synthesis, in addition to paraffin and heavy oil, there is also light oil that accounts for 50% of the total product. In the synthetic tail gas, most plants use activated carbon adsorption to recover this light oil. . In petroleum processing plants, coconut shell activated carbon is often used to recover light oil or gas gasoline in natural gas and processed gas (such as cracked gas) to increase the yield of light oil.

In gas plants and petroleum synthesis plants, coconut shell activated carbon is often used to remove sulfide in the gas in order to make the gas meet the conditions of use. activated carbon manufacturer For example, the sulfide contained in the synthetic gas will poison the synthesis catalyst and lose its activity, while the coconut shell activated carbon is used to remove the sulfide from the gas, and a good desulfurization effect can be obtained.
