Palm shell activated carbon is mainly made of palm shell. During the palm oil extraction process, the kernel is first extracted from the pulp, and then the shell of the kernel is cut off. The cut part is the palm shell (English name: Palm Kernel Shell (PKS)). The main producing areas are Indonesia and Malaysia. Palm shells are processed by high-temperature carbonization, activation and refining in a converter.
In the past, palm shells themselves were not of high value and were used as biofuels to mix with coal to generate heat energy. Today, many European countries including the United Kingdom, the Netherlands and Italy have begun to try to mix palm shells with coal to provide energy to alleviate the rising fuel costs and reduce carbon emissions. The calorific value of high-quality palm shells can reach 4600 kcal and the water content is less than 20. It is an efficient biomass fuel; in addition, palm shells can also be used to make activated carbon and decompose to make ethanol. As the technology becomes more and more mature, the potential of palm shells will become increasingly prominent. At present, as a raw material for fruit shell activated carbon, it is widely used in water treatment and purification processes.
