ACTIVATION OF HIGH-SELECTIVITY CATALYSTS AT OLEFIN OXIDE SYNTHESIS PLANTS Russian patent published in 2012 - IPC B01J23/50 C07D301/03 

FIELD: process engineering.

SUBSTANCE: invention relates to activation at epoxidation plants. Proposed method comprises: driving the reactor including high-selectivity silver-based catalyst to first temperature with the help of external thermal source despite the reactor design constraints and maintenance of gas flow to reactor in the range of 25-100% of designed flow rates, and introducing, at least, olefin and, then, oxygen to fed gas to cause reaction heat in said reactor for increasing first temperature to second temperature, and adjusting oxygen concentration at reactor outlet exceeding about 0.5%.

EFFECT: activation ensures reaching required reaction heat.
