Study on Pore and Surface Development of Activated Carbon Produced from Iranian Coal in a Rotary Kiln Reactor

Performance Analysis of Pilot Rotary Kiln for Activated Carbon Manufacture, Using a Steady State Mathematical Model

−− The physical activation of charcoal from eucalyptus wood has produced excellent results in laboratory tests. The obtained activated carbons have good adsorbent properties with surface areas over 500 m/g, low density and moderate attrition resistance. The activation process is strongly endothermic and involves gasification of the carbonaceous char by oxidation with either water vapor or carbo...

Preparation and Characterization of Activated Carbon Fibers from Liquefied Wood by ZnCl2 Activation

In this study, activated carbon fibers (ACFs) were prepared from liquefied wood by chemical activation with ZnCl2, with a particular focus on the effects of temperature and ZnCl2: liquefied wood-based fiber (LWF) ratio on yield, porous texture, and surface chemistry. The characterization and properties of these ACFs were investigated by nitrogen adsorption/desorption, Fourier transform infrared...

Regulatory Control of a Pilot Rotary Kiln for Activated Carbon Production

The design of a regulatory control strategy for a pilot rotary kiln to produce activated carbon is presented. A complex dynamic behavior with high non-linearity and an important dead time characterizes the rotary kiln operation. The main control objective of the process is to maintain the solid temperature profile inside of a narrow limit in order to produce an activated carbon with acceptable ...

Steady State Simulation of a Rotary Kiln for Charcoal Activation

−− This work presents a mathematical modeling and steady state simulation study of the pilot scale rotary kiln behavior, which was designed to activate charcoal obtained from the raw materials of region of Cuyo-Argentina. The proposed model aims for acquiring useful information to select operating conditions and design parameters. It is a simplified mathematical model that consists of a system ...
