Kinetic and thermodynamic investigation of CO2 adsorption-desorption on polyethyleneimine – mesoporous silica

Khader M.M., Al-Marri M.J., Kuti Y.O., Giannelis E.P., Qatar University, QA

This study combines measurements of the kinetics and thermodynamics of carbon dioxide adsorption-desorption on polyethylene mesoporous silica (PEI/MPS) in the temperature range from 45 to 85℃. The study was performed on two CO2 solid sorbents: [...]

Process Development and Pilot Demonstration of Cabon Capture Coupled Co-Production of Calcium Carbonate and Ammonium Sulfate

Zhu J., Xia S., Li J., Gong Y., Zhou J., Sichuan University, CN

Summary Carbon capture and storage (CCS) was affirmed to be a major component of a cost-effective portfolio of emission reduction strategies, by 2030 and beyond. However, there are still no full-scale applications on a commercial [...]

Multiscale Modeling and Experimental Study of CO2 Absorption into Ionic Liquid Reverse Micelle

Shi W., Hong L., Kusuma V.A., Hopkinson D.P., National Energy Technology Laboratory, US

Highly viscous solvents for gas absorption will lead to large pumping power requirement and large absorption/desorption tower, resulting in high capital cost. Ionic liquids (ILs) represent such examples even though ILs have been extensively studied [...]

Ruthenium Nanoparticles Media with in Ionic Liquid in Carbon Dioxide Valorisation to Methane

Bogel-Łukasik E., LAQV/Universidade Nova de Lisboa, PT

Carbon dioxide (CO2) is a very stable molecule and hydrogen reduction of CO2 to produce CO, the reverse water-gas shift reaction, only becomes thermodynamically favourable at temperatures higher than 1110K. CO2 emissions resulting from the [...]

Global Gas Flaring -The Energy Waste with Serious Environmental Impacts: Case Study of Iran

Soltanieh M., Zohrabian A., Gholipour M.J., Sharif University of Technology, IR

Gas flaring in oil production and oil and gas refining is a major environmental issue with great energy and economic loss. In this paper the global gas flaring and its adverse environmental impacts have been [...]

Gas-Assisted Gravity Drainage – A New Process for CO2 Sequestration and Enhanced Oil Recovery

Rao D.N., Louisiana State University, US

The current commercial practice of gas-based enhanced oil recovery processes involves either continuous gas injection (CGI) or Water-Alternating-Gas (WAG) injection. Over 60 commercial projects in West Texas and other parts of the world have amply [...]

H2 purification with PVDF/GTA blended membranes

Rabiee H., Soltanieh M., Mousavi S.A., Ghadimi A., Sharif University of Technology, IR

In this study, poly(vinylidene fluoride) (PVDF) and Glycerol Triacetate (GTA) have been selected as the main blending materials in order to fabricate membranes with a high separation ability for CO2/H2. GTA as a plasticizer possesses [...]
