Reaction carbon dioxide

Carbon monoxide and dioxide oxidize zinc vapor below 1100—1300°C although only the carbon dioxide reaction is significant. Rapid condensation of the zinc vapor avoids the formation of ziac-oxide-coated droplets, so-called blue powder. [Pg.404]

Reaction of the glycol, 70, affords an oxazolidinone rather than the expected carbamate (71) on fusion with urea. It has been postulated that the urea is in fact the first product formed. This compound then undergoes 0 to N migration with loss of carbon dioxide reaction of the amino alcohol with the isocyanic acid known to result from thermal decomposition of urea affords the observed product, mephenoxolone (74) this compound shows activity quite similar to that of the carbamate. An analogous reaction on the glyceryl ether, 75, affords metaxa-lone (76). [Pg.119]

This is the value stated in the carbon dioxide reaction you were asked to memorize that 1 mole of any gas occupies 22.40 liters at STP. [Pg.84]

The SR process involves two reactions, the conversion of hydrocarbon with steam to form hydrogen and carbon oxides [reaction (9.1)] and the WGS reaction for the conversion of carbon monoxide into carbon dioxide [reaction (9.2)] ... [Pg.290]

Equilibrium constant of reaction (1) for mechanism B in the carbon-carbon dioxide reaction as a function of temperature. [After S. Ergun, J. Phys. Chem. 60, 480 (1956).]...
Key (46) and Strickland-Constable (47) also support mechanism B for the carbon-carbon dioxide reaction. Strickland-Constable concludes from earlier measurements (46) that the rate of adsorption of carbon monoxide on carbon is too low to account for the retardation. [Pg.148]

As in the carbon-carbon dioxide reaction, mechanisms A and B can be treated for the cases where either the surface rearrangement or desorption of the carbon-oxygen complex is the slow step. This has no effect on the discussion except that the significance of the rate constant js in Equation (10) is altered, as previously discussed. [Pg.149]

A second mechanism for the carbon-steam reaction, similar to mechanism B of the carbon-carbon dioxide reaction, may be operative. Mechanism B ... [Pg.150]

Workers reporting orders of reaction for the carbon-carbon dioxide reaction include Graham (41), Strickland-Constable (48), Vulis and Vitman (60), Thring and Price (61), Armington (62), Vastola (63), Duval (64), and Karzhavina (65). As expected, they find reaction orders which vary from zero to one depending upon temperature, pressure, type of carbon reacted, purity of carbon, and geometric dimensions of the sample. [Pg.155]

Other workers 67, 85-89) have determined over-all activation energies for the carbon-carbon dioxide reaction, but the values have been affected to some extent by mass-transport control. Workers 6, 39, 40, 41) have also determined activation energies for the individual rate constants in Equation (5) but do not agree on their magnitude. The values of activation energy reported for rate constant i vary from 26.5 41) to 61.5 kcal./ mole 40). [Pg.159]

Gadsby and co-workers (63) report that for a coal charcoal, the rate of the carbon-steam reaction is greater by a factor of about three than the carbon-carbon dioxide reaction at 800° and a pressure range of 50 to 500 mm. Hg. The results of Pilcher et al. (68) and Walker et al. (85), using the same graphitized carbon rods and apparatus, essentially agree with this finding. At 1100°, the former workers report a reaction rate of 1.6 g./hr. at a steam partial pressure of 142 mm. Hg, which can be extrapolated to 4.8... [Pg.162]

Wicke (31), reacting spectroscopic electrode carbon at 0.1 atm. reactant pressure, gives the following equations for the rates of the carbon-oxygen and carbon-carbon dioxide reactions... [Pg.163]

Petersen 87, 120) discusses the use of profile data to understand better the mechanism of the carbon-carbon dioxide reaction. He reacted diameter rod samples in an apparatus previously described 85). Profile data were determined on the reacted rods as follows A 3 -in. hole was drilled through the center of the rod prior to placing it on an ordinary screwcutting engine lathe. Following incremental cuts of approximately 0.25 mm. from the exterior surface, the rod was removed from the lathe and weighed, and its diameter was determined by a micrometer caliper. For each cut, the apparent density of the material removed was calculated from the weight loss and volume of carbon removed. [Pg.178]

As was discussed in Sec. Ill, the rate of the carbon-carbon dioxide reaction can be expressed as... [Pg.199]
