Micro and Macro Thermal Degradation Behavior of Cotton Waste

Abstract

Fulfillment of energy demand and simultaneously to find proper solution of MSW from economical, social and environmental point of view waste-to-energy is the best option; also, the energy crisis is the new challenge in the front of world to push the economy in the progressive direction and simultaneous global warming and efficient use of energy are also challenging tasks. The thermal degradation of cotton was studied at temperature values () of 5,7,10,15,20 0 C/min in a nitrogen atmosphere utilizing the TG/DTG 32 horizontally differential systemic balance method, which occurs in three stages. The three separate independent parallel mechanism's defining the degradation was considered to derive the kinetic parameters. In first and second stage there might be degradation is with 10-15 % of total weight and 60-70 % of total weight respectively and finally 4-9 % residue remains in case of all heating rate. The elemental analysis of residue shows the existence of different elements in the residue on basis of which possible pollutants and cleaning requirement of thermal conversion system can be decided. The current TGA data was compared to sample decomposition using a Batch Type Pyrolyser (BTP) with a sample weight of 60 gm and a heating rate of 10 0 C/min in a nitrogen atmosphere. The information obtained will aid in the modelling, designing, and operations of MSW thermal conversion methods.
