Abstract

A method for activated carbon production from pine nut shells by pyrolysis technology followed by steam-gas activation is considered. The process of thermal decomposition of sample in an inert environment was studied; the main stages of the process were identified; the residual mass was determined. The iodine adsorption activity, total pore volume, mass fraction of moisture, mass fraction of ash, and specific surface area were found. The experiments have shown that the production technology is efficient and the raw material is promising for activated carbon production.

期刊介绍： Journal of Engineering Thermophysics is an international peer reviewed journal that publishes original articles. The journal welcomes original articles on thermophysics from all countries in the English language. The journal focuses on experimental work, theory, analysis, and computational studies for better understanding of engineering and environmental aspects of thermophysics. The editorial board encourages the authors to submit papers with emphasis on new scientific aspects in experimental and visualization techniques, mathematical models of thermophysical process, energy, and environmental applications. Journal of Engineering Thermophysics covers all subject matter related to thermophysics, including heat and mass transfer, multiphase flow, conduction, radiation, combustion, thermo-gas dynamics, rarefied gas flow, environmental protection in power engineering, and many others.
