Effect of Particle Size of NaX Zeolite on Adsorption of CO2/CH4
In the present work, the nano-NaX zeolite and micro-NaX zeolite were synthesized via hydrothermal method. Then, the adsorption capacities and isotherms of pure gases CO2 and CH4 on the synthesized zeolite nanoparticles were determined at three temperatures of 288, 298 and 308 K and various pressures from 1 up to 20 bar. Adsorption capacities of CO2 on the nano-sized zeolites NaX were showed to ...
متن کاملThe Effects of Gas Adsorption on Swelling, Visco-plastic Creep and Permeability of Sub-bituminous Coal
Unmineable coal is an important resource because of its potential to produce coalbed methane (CBM). CBM has grown to supply approximately 10% of US natural gas production and is becoming important worldwide as an energy source [1]. Furthermore, when CO2 is injected, it has the potential to enhance the amount of methane produced (ECBM) and to geologically sequestrate CO2 as an adsorbed phase. Th...
متن کاملStatistical Modeling of Adsorption and Selectivity of the Binary Gases of CO2 /CH4 , CH4 /H2 and CO2 /H2 on MWCNT-OH
Equilibrium adsorption property of multi-walled carbon nanotubes with OH group was studied using experimental design for the adsorption of CO2 , CH4 and H2 . The effect of temperature, pressure, their binary interactions and quadratic terms were studied for adsorption capacity of nanotubes and the results were analyzed by the face centered central composite design method and analysis of varianc...
متن کاملLow-Temperature Carbothermic Reduction of Indonesia Nickel Lateritic Ore with Sub-Bituminous Coal
In this work, the experiment was conducted to investigate the effect of temperature and sub-bituminous coal on upgrading nickel laterites ores by carbothermic reduction. The reduction was carried out in the muffle furnace at a temperature ranging of 800-1100 o C. The produced calcine from reduction step was grounded in vibrating mill, mixed with water and passed on a magnetic separator to separ...
متن کاملAdsorption and strain: The CO2-induced swelling of coal
Enhanced coal bed methane recovery (ECBM) consists in injecting carbon dioxide in coal bed methane reservoirs in order to facilitate the recovery of the methane. The injected carbon dioxide gets adsorbed at the surface of the coal pores, which causes the coal to swell. This swelling in confined conditions leads to a closure of the coal reservoir cleat system, which hinders further injection. In...
