Our coconut activated carbon facility in India is the largest in the region
Our coconut activated carbon facility in India is the largest in the region with annual production capacity of 100 million pounds of carbon. Black Opal Group factories pursue uncompromising quality standards in all stages of process and operation activities. For this, a meticulous quality control program is operated throughout the entire process from selection of raw material to final quality assurance prior to shipment.
Uncompromising Quality Standards
Our craving for uncompromising quality starts at the selection of raw material itself. Charcoal is sourced from selected outlets after rigorous quality inspections.
Our factories employ state-of-the-art equipment and technology and are supported by highly qualified and skilled technicians. No-compromise quality control is their top priority.
Specially designed crushing and screening machines assure a great degree of control over particle size to precisely meet the application-specific mesh size range requirements of our customers. Quality of IndoCarb brand coconut carbon products has been extensively tested and acclaimed by major industry leaders and reputed laboratories around the world.
Carbonization
Coconut shells in the form of lumps are carbonized to convert coconut shells to char or charcoal by pyrolysis, which is chemical decomposition by heating in the absence of oxygen. Temperatures usually do not exceed 700 C, reducing volatile content to less than 20%.
Steam activation
The carbonized base material is activated at high temperature, about 1,100 C / 2,012 F, in steam. The reaction between carbon and steam takes place at the internal surface, removing carbon from pore walls and enlarging the pores.
Sizing and finishing
Output from the rotary kiln is processed in the postproduction plant where it is crushed and screened to different sizes and to remove fines and dust for granular activated carbons. Powdered activated carbons are produced by further grinding the granules with a gentle pulverizing action.
The steam activation process allows pore size to be readily altered and carbons can be produced to suit specific end uses. Activation temperature and activation time are important to create internal pore networks and impart surface chemistries inside each particle.
