How to make charcoal from palm kernel shell?

Palm kernel shells are a byproduct of the palm oil industry and have great potential as a raw material for producing high-quality charcoal. To convert palm kernel shells into charcoal, a controlled combustion process called carbonization or pyrolysis is required. This process is significant because it not only adds value to palm kernel shells, which are otherwise considered waste, but also provides an environmentally friendly alternative to traditional charcoal. Below, I will explain in detail how to make charcoal from palm kernel shells.

1. Collection and preparation of palm kernel shells

The first step in making charcoal from palm kernel shells is to collect and prepare the palm kernel shells. Palm kernel shells can be obtained from palm oil mills, which separate the palm kernel shells from the palm kernels during the process of extracting palm oil. Preparation involves pretreatment of their size and moisture content. Generally, oversized raw materials are processed into appropriate sizes using a shredder. Also, the moisture in the palm kernel shells will affect the quality of the charcoal, so the moisture must be reduced to around 10-15%. There are two options to achieve this goal. One is to spread the palm kernel shells evenly and let them dry naturally, which is a relatively cheap method. Or use a dryer to speed up the drying process, so that the palm kernel shells can reach the ideal drying state in a shorter time.

2. Carbonization Process

The carbonization process of palm kernel shells is to heat them in an oxygen-free environment to drive off volatile compounds such as water, tar and gas, and finally obtain a product with high carbon content - charcoal. This process is carried out with the help of palm kernel shell carbonization machines.

Common carbonization machines includes traditional carbonization kilns or more advanced carbonization machines. Carbonization kilns have a long history and are simple to operate, but they are inefficient, time-consuming, and pollute the environment. DOING carbonization machines are more advanced and can improve efficiency, reduce energy consumption, control temperature, and ensure product quality.

Therefore, considering many factors, especially the two key factors of environmental protection and high efficiency, it is more recommended to choose palm kernel shell carbonization equipment with more advanced technology, so as to achieve a win-win situation of economic and environmental benefits in the production process.

3.Cooling

After the carbonization (pyrolysis) process is completed, the generated charcoal needs to be cooled. At this time, the cooling system inside the palm kernel shell carbonization machine comes into play, which can ensure that the charcoal can be safely cooled to room temperature, so as to prevent the charcoal from being exposed to the air and burning. The screw will then push the cooled charcoal to a pre-set collection position.

Henan DOING Company has more than fourteen years of rich experience, and its team consists of highly qualified engineers and professional sales staff, committed to providing customers with the best quality solutions and proper carbonization machine. Our carbonization machine adopts advanced carbonization technology, which can achieve precise control of temperature and oxygen supply, ensuring that the biomass material can undergo a slow and uniform pyrolysis process in an oxygen-deficient environment, which not only greatly improves the output rate of the final product, but also ensures the quality of the charcoal.

Besides, DOING carbonization machine is also equipped with efficient heat recovery system and exhaust gas treatment system. The combustible gas produced during the carbonization process has the potential to be used as fuel and can be used in the drying or carbonization process. In this way, it not only reduces the impact on the environment, but also further improves the energy efficiency of the entire production process.

Through these steps, you can produce charcoal from palm kernel shells efficiently with the help of advanced carbonization equipment. If you are interested in charcoal production business, welcome to contact us for more details and quotation of carbonization machine.
