peer agreement (net): +4| oxy-dehydrogenation process أزالة الهيدروجين (نزع الماء) بالأكسدة -من المشتقات العضوية Explanation: - نزع الماء ورد في معجم المصطلحات العملية والفنية والهندسية لأحمد شفيق الخطيب See this http://cat.inist.fr/?aModele=afficheN&cpsidt=1628096 The oxidation of propane over a Mn3O4 catalyst has been investigated with oxygen to propane ratios up to 2:1. High selectivities to the oxy-dehydrogenation product propene have been obtained at low conversions, with yields up to 5% and productivities up to above 1.5 KgC3H6/Kgcat h. Data on the mechanism and on the reaction pathways have been derived from an evaluation of the reaction kinetics and from FT-IR experiments. The main by-reaction with respect to oxy-dehydrogenation is propene over-oxidation to CO2. Direct total oxidation of propane to CO2 can become predominant only in oxygen excess. Isopropoxide species act probably as surface intermediate species in propene synthesis. العملية تتضمن إزالة الهيدروجين (نزع الماء ) من المركب العضوي بتعريضة للأوكسجين عن طريقة الاكسدة للحصول على المشتقات الأخرى -------------------------------------------------- Note added at 51 mins (2008-11-15 10:53:37 GMT) -------------------------------------------------- A catalytic process for dehydrogenating light hydrocarbons fromcrude oil to their corresponding mono- or diolefins; McGRAW-Hill Engineering Dictionary |
