1. The chemical nature of CO2 adsorption in zeolite A
Abstract : The climate changes are accelerated by increasing levels of carbon dioxide in the atmosphere connected to the fossil-fuel-based energy system. Substantial reforms of the system are needed immediately and could include the implementation of carbon capture and storage (CCS) technologies. READ MORE

2. Structured zeolite adsorbents
Abstract : Zeolites are microporous crystalline aluminosilicates with unique properties, and therefore used in adsorption processes, for membrane separation, in catalysis, and in sensor technologies. Pressure swing adsorption (PSA) is a commonly used technology for purifying gases and is based on the ability of materials like zeolites, to selectively adsorb and desorb particular gas molecules as the gas pressure is increased and reduced, respectively.

3. Structured zeolite adsorbents for PSA applications
Abstract : Zeolites are microporous crystalline aluminosilicates with unique properties, and are therefore used in adsorption processes, for membrane separation, and as catalysts. Thin zeolite films grown on honeycomb monolith supports represent a new type of material and may be used as structured catalysts and adsorbents, and improve the processes significantly. READ MORE

4. Optimization of structured adsorbents for gas separation processes
Abstract : Conventional gas separation processes using packed beds of beads or granules suffer from high pressure drop and mass transfer resistance when higher throughputs are required, leading to lower productivity and recovery and higher power consumption. This restricts their application to low throughputs and makes them less attractive compared to other processes for large volume production and high productivity. READ MORE

5. Bio-SNG from Thermal Gasification - Process Synthesis, Integration and Performance
Abstract : Biomethane or synthetic natural gas (Bio-SNG) produced from gasified renewable woody biomass is a promising option for replacing fossil natural gas. The complete interchangeability with natural gas in all its conventional applications such as in the power generation, transportation and chemical industry sector is of particular interest. READ MORE
