Carbon monoxide attack of refractories
… of fire clay refractories due to the action of carbon monoxide has been studied tor a period at about fifty years. The most important application is in blast furnace refractories. Similar failures due to carbon deposition, involving other gases such as methane, have been noted and less …

Study of atmospheric carbon monoxide and methane
The analysis of isotope ratios is widely used for the investigation of atmospheric trace gases. We measured the stable isotopes d13C and dD of atmospheric CH4 as well as d13C, d18O and the 14CO concentrations of atmospheric CO at Izana, Tenerife, from 1996 to 1999. We report the first directly …

Dynamics of Carbon-Monoxide Oxidation on Platinum
This work presents a study of kinetics of CO oxidation on a platinum ribbon in a gradientless reactor. An isothermal condition was maintained on the catalyst surface. The reaction rate was measured by a calorimetric technique, and measurements of the effluent CO(,2) concentration were made with an …

Carbon Monoxide Prodrugs for Targeted Cancer Therapy
Carbon monoxide (CO) is endogenously produced in the body through the breakdown of haem by haem oxygenase enzymes. Since this discovery, CO has been recognised as a gasotransmitter alongside nitric oxide and hydrogen sulfide. Beyond established physiological roles, CO has shown therapeutic …

Mechanism of carbon monoxide oxidation at the active site [Ni-4Fe-5S] cluster of carbon monoxide dehydrogenase from Carboxydothermus hydrogenoformans
The carbon monoxide (CO) metabolism relies on CO-dehydrogenase (CODH) that oxidizes CO with H2O to CO2. The crystal structures of the native Ni-Fe CODHIICh from the CO-grown thermophilic hydrogenogenic anaerobic bacterium Carboxydothermus hydrogenoformans reveal the active site as a [Ni-4Fe-5S] …

The oxidation of carbon monoxide on zinc oxide
… was made of the kinetics of the oxidation of carbon monoxide to form carbon dioxide. The catalyst was high purity zinc oxide. A liquid nitrogen trap was used to remove the product carbon dioxide, thereby virtually eliminating any poisoning effect of CO2 on the reaction. A natural convection …

Historical anthropogenic emissions of carbon monoxide, 1850 - 2000
We present a bottom-up emission inventory of carbon monoxide (CO) from fossil fuel and biofuel combustion from 1850 to 2000. We reconstruct fuel consumption data of brick and cement industry, as well as production data of iron and steel industry. We develop technology divisions for the four …

The generation of carbon monoxide in compartment fires
For the purpose of fire analysis and fire safety engineering, the development of empirical correlations for major species yields in compartment fires has become an important priority due to the inability to calculate these quantities from first principles. Studies of simplified upper layer …

Carbon Monoxide Generation and Transport from Compartment Fires
… included species mole fractions of oxygen, carbon dioxide, carbon monoxide, and unburned hydrocarbons, along with gas pressure (used to determine gas velocities) and gas temperatures. Species mappings performed at the exit plane of the compartment indicated that the exiting species are not …

STUDIES ON THE REACTION OF HIGH-DOSE HYDROXOCOBALAMIN AND ASCORBIC ACID WITH CARBON MONOXIDE: IMPLICATIONS FOR TREATMENT OF CARBON MONOXIDE POISONING
… hydroxocobalamin should be capable of producing carbon dioxide (CO2) from carbon monoxide (CO) in blood, and that this conversion should be detectable. Using resonance raman spectroscopy we demonstrated that a mixture of hydroxocobalamin and ascorbic acid could create the reduced form of …

Evaluation of Carbon Monoxide as a Therapeutic for Preeclampsia
… products. This has lead to the notion that carbon monoxide (CO), one of the byproducts of cigarette combustion, may confer this decrease in PE risk. Endogenously, CO is produced through the degradation of heme by heme oxygenase (HO), and it has been suggested that modulation of the HO/CO …

Palladium-catalyzed reactions of ammonia, carbon monoxide, and cyanide
… palladium complexes also catalyzed the aminocarbonylation of aryl bromides and aryl iodides with ammonia and carbon monoxide. Primary benzamides formed in good yields from aryl bromides and aryl iodides with 2 mol % of Pd[P(o-tol)3]2 and CyPF-t-Bu under 3 atm total of ammonia and carbon …

Catalytic reaction in the process of carbon monoxide disintegration
… by the reduction of Fe₂O₃ is a catalyst for carbon monoxide disintegration; (3) The catalytic process consists of the adsorption of CO, the formation of intermediates FeC, Fe₂C , and Fe₃C , and the decomposition of these intermediates.
