CO2 is the main greenhouse gas emitted from the combustion of fossil fuels and is considered a threat in the context of global warming. Carbon capture and storage (CCS) schemes embody a group of technologies for the capture of CO2 from power plants, followed by compression, transport, and permanent storage. Key advances in recent years include the further development of ne...

in this study, bimodal meso-porous silica (uvm-7) synthesized and fabricated amino silane modified supports were characterized by powder x-ray diffraction (xrd), n2 adsorption/desorption, transmission electron microscope (tem), elemental analysis and titration. capacity of co2 capture on modified bimodal pore structure silica at 70°c was calculated using breakthrough curves; and it was found th...

an air filter is a significant element of any mechanical ventilation system. however, the importance and performance evaluation of air filters have not been well publicized and related scientific reports are scarce. in this study, a transportable, off-line, air filter-testing unit (the unit) was designed and utilized to simulate the filter housing of a mechanical ventilation system. the unit wa...
