Steel reactor carbon oxide formation

With a steel reactor it is shown that preoxidation of the foil and the reactor surface results in much higher coke formation on the foil compared with prereduction of the reactor system (Figures 6 and 7). This is not surprising since Fe and Ni present on the oxidized surface are known to be good catalysts for carbon formation (21). Prereduced foils, which contain mostly Cr and Mn on the surface, produce much less coke. In agreement with this, the coke deposit from the preoxidized foil surface contains Fe (characteristic of catalytic coke formation) whereas the deposit on the prereduced foils contains effectively no Fe (20). [Pg.56]

The authors of [236] performed a more thorough analysis of the products of this reaction in the same two-section stainless steel flow reactor with a Pyrex liner at a pressure of 34 atm. The main oxidation products detected in the gas and liquid phases were methanol, ethanol, carbon oxides (primarily CO), water, methane, ethylene, propane, n-butane, formaldehyde, acetaldehyde, formic acid and acetic add, dimethoxymethane, dimethyl ether, acetone, and hydrogen. The selectivity of formation of incomplete oxidation products was high, while the selectivity to carbon oxides did not exceed 16—28% at an oxygen concentration of 3.6—12.8%. TTre best results were obtained at 287 °C and an oxygen concentration of 6.6% the ethane conversion was 6.2% whereas the total selectivity of alcohols was 57% at an ethanol-to-methanol ratio of 0.47. The liquid products contained 37% methanol and 17% ethanol. [Pg.172]
