Carbon dioxide reforming of methane on Ni-based bimetallic catalyts
Ay, Hale; Üner, Deniz; Department of Chemical Engineering (2014)
Carbon dioxide reforming of methane is a promising process for the utilization of two important greenhouse gases and the production of synthesis gas with a lower H2/CO ratio which is preferred in Fischer–Tropsch synthesis. Ni catalysts have taken great interest in dry reforming of methane due to their high catalytic activity, easy availability and low cost. However, the main restriction of Ni-based catalysts is the formation of carbon which causes catalyst deactivation. The objective of this thesis was to r...
Carbon monoxide oxidation under oxidizing and reducing conditions with alkali-metal and palladium doped tin dioxide
Mirkelamoğlu, Burcu; Karakaş, Gürkan; Department of Chemical Engineering (2006)
The investigation of CO oxidation with supported noble metal catalysts to develop a fundamental understanding of the nature of the active sites, adsorbate-surface interactions, surface reaction pathways and the role of promoters is of prime importance for development of highly active and selective catalyst formulations for low temperature oxidation of carbon monoxide. Low temperature CO oxidation catalysts find applications in monitoring and elimination of CO in chemical process exhaust gases, in on-board c...
Carbon monoxide hydrogenation on supported manganese-ruthenium catalysts
Tercioglu, T; Akyurtlu, JF (1996-03-14)
CO hydrogenation over a catalyst with the nominal composition of 6.3% Mn-2.5% Ru/Al2O3 was studied in a now system with a differential fixed-bed reactor operating under atmospheric pressure. The temperature was varied between 553-613 K, H-2/CO ratio 1-3 and space velocity 5100-27600 cm(3)/(g h). The presence of manganese caused the product distribution to shift to lower olefins. For this catalyst system, secondary alkene hydrogenation was found to be significant. The activity and selectivity pattern of the ...

Ciprofloxacin, a second-generation synthetic fluoroquinolone derivative widely used in human and veterinary medicines, has the potential to pose a serious risk to aquatic organisms and humans. The current research investigated the removal of ciprofloxacin using biochar treated with clay mineral and subsequently activated with carbon dioxide (CO2) produced at two different pyrolysis temperatures (350 and 650 °C). Batch adsorption experiments were carried out to assess the removal efficiency of ciprofloxacin ...
Carbon dioxide removal in steam reforming : adsorption of CO2 onto hydrotalcite and activated soda
Fıçıcılar, Berker; Doğu, Timur; Department of Chemical Engineering (2004)
Conversion of natural gas and other light hydrocarbons via steam reforming is currently the major process for hydrogen production. However, conventional hydrogen production technologies are not cost effective and therefore, cost is the biggest impediment to use hydrogen in fuel cell applications. In order to optimize and overcome cost problems in hydrogen production, sorption and membrane enhanced reaction processes are the two novel technologies for in situ operation of reforming and removal of carbon diox...
