Preparation porous bio-char and activated carbon from rice husk char study has been conducted in this study. Rice husk char contains high amount silica that retards the porousness of bio-char. Porousness of rice husk char could be enhanced by removing the silica from char and applying heat at high temperature. Furthermore, the char is activated by using chemical activation under high temperatur...
The separation of ethanol, propanol, and butanol from aqueous solutions was studied using adsorption on bone char. Adsorption kinetics thermodynamic parameters this method were at different conditions pH temperature. Results showed that the maximum capacities these bioalcohols obtained 6 20°C. An exothermic identified, which can be mainly associated to hydrophobic interactions between char surf...
The application of biochars to improve soils and to mitigate global climate change is a popular research area all over the world, although it is not a new topic. In our study, wood chips char (BC) and animal bone char (ABC) were applied. The pot experiments were conducted under laboratory conditions. 2 grams of rye-grass (Lolium perenne) were seeded into each pot. The following various soil par...
This study presents an experimental evaluation of the rate of nitric oxide reduction on the char surface. It addresses the claim that the rate for the destruction of nitric oxide on the char surface has been underpredicted due to char deactivation in the process of char formation. Experiments conducted with chars produced in situ, char previously produced at pulverized combustion conditions, an...
Tar and char can be regarded as unwanted byproducts during the gasification process. In this study, three types of catalyst, i.e., biomass char (bio-char), nickel supported on biomass (Ni+bio-char), and nickel supported on bio-char (bio-char+Ni), were studied to compare the catalytic effects of different preparation methods on tar model compound removal. The structural characteristics of the th...
