Synthesis and purification of Carbon nanotubes
In this study, multi wall carbon nanotubes (MWCNTs) were synthesized by Chemical vapor deposition (CVD) method using two different catalysts (Fe nanoparticles) and (Ni nanoparticles) with two different substrates: Quartz and Alumina. Acetylene gas was used as a carbon source and Argon as a carrier gas at different temperatures and different times to study the effects of these parameters on CNT...

متن کاملCarbon 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...

متن کاملNoble Gas Anomalies and Synthesis
There are two types of planetary noble gases. One containing isotopically " anomalous: argon ,krypton and xenon but isotopically " normal " helium and neon, was derived from outer stellar regions. The other, consisting almost entirely of isotopically " normal " argon, krypton and xenon with little or no helium or neon, was derived from inner stellar regions. Mixing of nucleosynthesis products f...
