Activated Carbon Production from Coconut Shell

No need to doubt the activated carbon from coconut shell is the most popular activated carbon now from a group of renewable raw materials (renewable resource). Indonesia is the largest coconut plantation owner in the world but the production of activated carbon from coconut shell is still low. Unlike palm oil which is generally owned by large plantations with organized businesses with hundreds of processing plants, coconuts are mostly owned by smallholder plantations, less organized so that the processing industry does not develop. So, how can coconut plantations and the industries develop? Before answering this question, it should be noted that coconut plantations and their processing industries suffered a lot of setbacks. This is because the coconut sector still lacks attention. In addition, the pattern of approaches for the coconut industry whose owners are mostly community plantations should also be different from the oil palm industry which is generally owned by large plantation…

Bagasse Pellet and EFB Pellet for Power Plant Fuel

Baggase pellets and EFB pellets are groups of agricultural waste pellets (agro-waste pellets) whose quality is below wood pellet. Not all power plants can use the two types of pellets above. This is because pellets of agricultural wastes generally have a large ash content and chemical content of ash which cannot be accepted by certain types of electricity generation technology. In general, agricultural waste pellets (agro-waste pellets) contain high potassium (kalium) with low melting point and chlorine that's corrosive element, so it is generally not suitable for pulverized combustion system type plants. The pulverized combustion system operates at high temperatures more than 1400 C. Power plants that operate at lower temperatures such as gasification and fluidized bed combustion (FBC) can use bagasse pellet and EFB pellet as fuel. Palm kernel shell is also suitable for this type of combustion technology, while wood pellet because it comes from wood (woody biomass) generally can…

Production of Pharmaceutical Grade Activated Carbon

Surface area is one of the important parameters for activated carbon. But the parameter surface area does not always represent the quality and use of the activated carbon. This is because it is related to the size of the molecule that is intended to be adsorbed from the activated carbon. Activated carbon has different pore size and distribution structures depending on the raw material and the production process. The pore size includes micropore (adsorption section, <2 nm), mesopore (transport pores, 2-50 nm) and macropore (access pores, 50-1000 nm). A typical commercial activated carbon has an internal surface area of ​​around 1000 m2 / gram with an internal pore volume of 0.3-3 ml / gram. A certain molecule of a certain size can only enter the activated carbon pores if it is smaller, and vice versa. The target molecule to be adsorbed with its size must be adjusted to the type of activated carbon used.

The use of activated carbon as a drug was recorded starting from the use of cha…

Foodgrade Activated Carbon Production

Similar to bio pellet fuel where each user requires certain specifications of the type of pellet fuel, so does activated carbon. Basically every bio pellet fuel also has its own user or market (to be more clearly read here) as well as activated carbon. The choice of the standard type and production process will affect the quality or characteristics of the activated carbon. Like bio pellet fuel that can be made from various types of biomass, activated carbon can also be made from carbon-based materials such as biomass and coal. Wood pellets are one of the most popular products from bio pellet fuel, and coconut shell activated carbon is one of the most popular activated carbon products.

One of the uses of activated carbon is for the food sector and for that also has its own characteristics. The most important thing about activated carbon for food is about halal, for example, activated carbon can be made from animal bones, if the bones of an animal are haram (prohibited) like pigs, then …
