Title:
CONTROLLED PRESSURE HYDROTHERMAL TREATMENT OF ODH CATALYST
Document Type and Number:
WIPO Patent Application WO/2018/015851
Kind Code:
A3
Abstract:
The preparation of an oxidative dehydrogenation catalyst comprising Mo, V, Nb and Te using a hydrothermal step the activity and reproducibility of the catalyst is improved by conduction the hydrothermal step at higher pressures while permitting gaseous products to leave the reactor. In some instances a condenser may be upstream of the pressure relief valve.
