Thermochemical conversion of bean pods to carbon materials and gas
(Freund Publishing House Ltd, 2008)
The preparation of activated carbons from bean pods by chemical (K(2)CO(3)) and physical (water vapor) activation was investigated. The carbon prepared by chemical activation presented more developed porous structure than ...
Characterization of Bulgarian oil shale kerogen revealed by oxidative degradation
(Elsevier GMBH, Urban & Fischer Verlag, 2009)
A 13-step alkaline permanganate degradation of Bulgarian oil shale kerogen concentrate at ambient temperature was carried out. A high yield of oxidation products (90.1%) and a low yield of gaseous products (2.79%) were ...
Preparation and characterization of mesophase pitch based carbon foam produced at low pressure
(Springer, 2015-08)
The morphological changes during carbon foam synthesis depend on the process pressure and temperature, melting temperature, and viscosity of the mesophase pitch. This study is focused on interpreting the foaming mechanism ...
