A sealed hydraulic tank system for a mining shovel includes an upper tank and a lower tank. The cable organizer includes a cable spool that is mountable to an underside of a support surface and is used to organize, store and separate cables and power cables used to operate and power electrical appliances. Some oxychlorination catalyst compositions and processes disclosed herein can increase the optimal operating temperature, and thereby increase the production capacity of an existing reactor, such as a fluid-bed reactor, compared to other oxychlorination catalyst compositions.
