Das Sohio-Verfahren ist ein chemisch-technischer Prozess zur Herstellung von Acrylnitril und Acrolein. Er wurde vom gleichnamigen Unternehmen Sohio entwickelt. Nach dessen Übernahme durch BP wurden die Anlagen weiter betrieben und laufend verbessert. Die Synthesen laufen im Rahmen einer katalytischen Oxidation von Propen ab. Das Verfahren zur Herstellung von Acrylnitril ist sogar der größte industrielle Ammonoxidationsprozess. WebExamples of commercially used catalysts are supported CuO (used in the Shell process) and Bi203/Mo03 (used in the Sohio process). In both processes, the reaction is carried out at temperature and pressure ranges of 300-360°C and 1-2 atmospheres. In the Sohio process, a mixture of propylene, air, and steam is introduced to the reactor.
