Biogas Purification using Coconut Shell Based Granular Activated Carbon by Pressure Swing Adsorption

Biogas Upgrading by Pressure Swing Adsorption

Adsorption of volatile organic compounds by pecan shell- and almond shell-based granular activated carbons.

The objective of this research was to determine the effectiveness of using pecan and almond shell-based granular activated carbons (GACs) in the adsorption of volatile organic compounds (VOCs) of health concern and known toxic compounds (such as bromo-dichloromethane, benzene, carbon tetrachloride, 1,1,1-trichloromethane, chloroform, and 1,1-dichloromethane) compared to the adsorption efficienc...

Carbon Dioxide Capture and Hydrogen Purification from Synthesis Gas by Pressure Swing Adsorption

Global warming has become more and more serious, which is caused by greenhouse gases. Cutting down the emission of CO2 has already become one of the major research target in the world. This study utilized a pressure swing adsorption (PSA) process to separate high-purity hydrogen and to capture CO2 from synthesis gas, which is the effluent stream of water-gas-shift reactor. The purified H2 can b...

Adsorption Process for Wastewater Treatment by using Coconut Shell

Adsorption of heavy metal on the solid surfaces is an important technique to remove them from the industrial wastewaters. The purpose of the present study is to evaluate the ability of agro-waste material coconut shell to remove Cr (VI) from wastewater. The extant of removal was found to be dependent on pH, contact time, adsorbent dose, concentration of metal and particle size. The adsorption f...
