Platinum Metals Review - Volume 1, Issue 2, 1957

Reforming processes using platinum catalysts have become of major importance in petroleum refining during the past seven years. They enable the octane rating of naphthas to be greatly increased, and are more economical than any other refining process for the production of high octane gasoline. In this article the general nature of the processes is described and the Platforming process is considered in more detail.

This note, a communication from the Development Laboratory of Johnson, Matt hey & Co., Limited, describes a temperature controller for resistance furnaces with platinum alloy windings. The control signal is obtained by monitoring the resistance of the winding, so that no separate temperature-sensing element is required. Provision is made for control of the, initial heating rate to avoid thermal shock.
