Because of a high initial concentration of oxygen, [O2]0 ¼ 14%, its complete conversion caused a substantial heating of the mixture, up to 500 C, so that the final temperature could exceed 1000 C, well deep in the OCM temperature range. Therefore, the effects described below, despite the monotonic decrease of the initial temperature in this series from 630 to 515 C may be related, at least in part, to the heating of the mixture. However, the results show that the COx/C2þ ratio changes with the pressure, as does the C2H6/C2H4 ratio, showing an increase in the relative yield of ethylene (Fig.
The content of aldehydes in the liquid products decreased monotonically with increasing pressure, whereas the content of organic acids remained almost constant. The concentrations of the other detectable organic products (ethers and ketones), except for methyl ethyl ketone, also increased with the pressure. The ratio of the total concentration of alcohols to the total concentration of aldehydes in the produced liquid, as in other studies, increased monotonically with the pressure (Fig. 9) and almost exactly reproduced the dependence in Fig.
Concentration, 6%, after which it decreased gradually. Up to an initial oxygen concentration of 10%, the overall yield of liquid products increased almost linearly, mainly due to the formation of water. The concentration of methanol in the liquid oxidation products formed in the quartz reactor decreases almost linearly with increasing oxygen concentration from its maximum value of w42% at [O2]0 ¼ 2e3% (Fig. 41). The nature of a small decrease of the methanol concentration at initial oxygen concentrations below 2% is not clear.
