WORKING PRINCIPLE OF THERMACT-Mt THERMACT-Mt reduces the activation energy required to release the Volatile Matter in Coal. This Catalyst, when added with Coal before Carbonization, helps in faster evolution of the Volatiles. Inherent Moisture present in Coal is utilized to generate heat in the presence of Carbon.

THERMACT-BF : CIFMR Studies THERMACT-BF was studied under Lab conditions at CIFMR, Dhanbad (Central Institute of Fuel & Mining Research) The following tests were carried out on samples of Iron Ore, Iron Ore+Coke and Iron ore + Coke + THERMACT-BF in the dosage of 1 : 6000. Thermo Gravimetric Analysis (TGA) A TGA is done to study the rate of change in weight of a material as a function of temperature in a controlled atmosphere. Abhitech Energycon Ltd., INDIA

THERMACT-BF : CIFMR Studies Differential Scanning Calorimeter(DSC) A DSC measurement provides vital information, qualitative & quantitative on physical & chemical changes that occur in materials as a result of exothermic or endothermic processes. Reduction Behavior : The Degree of Reduction of Iron ore + coke with / without THERMACT-BF. DR can be measured using the formula ; DR = ( W / TO ) x 100 where W = Loss in weight of pellet TO = Total Oxygen Abhitech Energycon Ltd., INDIA

THERMACT-BF : CIFMR Studies - RESULTS The results & consequential inferences from above tests are; The combustion of Coke starts at a lower temperature on addition of THERMACT-BF as compared to Base sample. The Activation temperature of reaction of Iron Ore with Coke has reduced on addition of THERMACT-BF. As per DR, it was observed that the Efficiency of reduction of Iron Ore and Coke increased on addition of THERMACT-BF. Gas Chromotography tests confirm that no harmful gases are evolved on addition of “THERMACT-BF” to Iron Ore and Coke. Abhitech Energycon Ltd., INDIA
