RMP - Shell Chemical

Martinez, California

The Shell Chemical Plant consists of two main batch processes: Ethylene Oxide (EO) Catalyst and RM-17. The EO Catalyst Process produces a silver-based catalyst that is sold to industrial customers that convert hydrocarbons to ethylene oxide. A specially formulated impregnating solution is produced at the Plant and absorbed onto carrier rings to make the EO Catalyst products. No CalARP/RMP regulated materials are used to produce RM-17. Ethylenediamine is used to produce the EO catalysts.
