Methods for applying solution catalysts to reactor surfaces

A method for treating interior surfaces of a fluidized bed polymerization reactor system, said surfaces including at least one sensitive surface and at least one nonsensitive surface, said method including the steps of:

• (a) applying a zinc coating to at least one said sensitive surface but not to at least one said nonsensitive surface;
• and
• (b) after step (a), applying a solution catalyst at least substantially uniformly and in liquid form to each said sensitive surface and each said nonsensitive surface.

A method for treating at least one interior surface of a fluidized bed polymerization reactor system, including the steps of:

• (a) applying a solution catalyst to each said surface, where a catalyst component of the solution catalyst comprises at least one chromium containing compound, wherein contents of the reactor during step (a) have a dew point temperature, and said contents include the solution catalyst, while maintaining conditions in the reactor system, including reactor temperature, sufficient to maintain the dew point temperature at the reactor temperature during uniform wetting of each said interior surface by the solution catalyst;
• and
• (b) after step (a), introducing oxygen into the reactor system to cause controlled oxidization of at least some of the chromium containing compound applied in step (a).
