Fibre Chemistry Aims and scope

Conclusions

-- Gaseous and resinous products are evolved in the thermo-oxidation of spun pitch fibres. The main components of the gas are H2O, CO, and CO2. The effect of rate of temperature elevation, velocity of the air stream, and the duration and temperature of thermo-oxidation on the amount of evolved oxidation products, and oxygen content and sample weight gain have been investigated.

-- The kinetics of evolution of H2, CO, CH4, and CO2 has been studied in the carbonization of spun and oxidized pitch fibres. It has been shown that during temperature elevation CO2 is initially evolved, and then CO and CH4. H2 is evolved at temperatures of 540°C and higher.
