Thermal Degradation and Organic Chlorine Removal from Mixed Plastic Wastes
Plastic waste accumulation has been growing due to the increase in plastic generation and the lack of infrastructure for recycling. One of the approaches is to treat the mixed plastic waste (MPW) through thermal processes to produce feedstocks for other ...

Degradation in a Thermal Barrier Coating [PDF]
The failure of a thermal barrier coating involves cracking and spalling of the ceramic layer, primarily brought about by bond-coat oxidation during operation. The present investigation focuses on the microstructural and microchemical changes in a thermal barrier coating, oxidized in air for 1 and 10 h at 900{degree}C.

Thermal Degradation on Already Oxidatively Degraded Solutions
AbstractCO2 capture with alkanolamines has been in use since 1930, where 2-ethanolamine (MEA) is the most studied absorbent for post-combustion. In order to prevent degradation, it is important to understand the degradation mechanisms, which in turn requires knowledge of both stoichiometry and kinetics of the reactions and chemical pathways associated ...

Combined kinetic analysis of thermal degradation of polymeric materials under any thermal pathway [PDF]
Combined kinetic analysis has been applied for the first time to the thermal degradation of polymeric materials. The combined kinetic analysis allows the determination of the kinetic parameter from the simultaneous analysis of a set of experimental ...

Utilization of temperature kinetics as a method to predict treatment intensity and corresponding treated wood quality : durability and mechanical properties of thermally modified wood [PDF]
Wood heat treatment is an attractive alternative to improve decay resistance of wood species with low natural durability. However, this improvement of durability is realized at the expense of the mechanical resistance.
