Steel optimal oxidation conditions

Kong, Lu, Yang, and Wang (2007) investigated a stainless-steel-supported zeolite silicalite-1 membrane reactor packed with an iron oxide catalyst for styrene production. Without a reduction in the styrene selectivity, the conversion in the membrane reactor was nearly 7% higher than the hxed-bed reactor at temperatures above 600 °C. Yua and Xu (2011) extracted H2 from ethylbenzene to the styrene reaction side by a palladium membrane. They reported that under the optimal reaction conditions (T = 570 °C, P = 1.4 atm, liquid hourly space velocity = 0.36/h), the styrene yield shows an 11.3% increase in membrane reactor with respect to the conventional one with no considerable change in styrene selectivity. 

On the basis of obtained data of cyclic voltammograms for 3d metals oxides electrodeposition the optimal conditions (current density, potential, process time, electrolyte composition, temperature) for dense oxide films (Ni, Cr and Co) deposition on steel foil have been elaborated. Data relating to several best films are summarized in Table 1.
