Platinum Metals Review - Volume 20, Issue 1, 1976

In the most recent innovation in catalytic reforming very small quantities of the platinum catalyst are continuously withdrawn, regenerated, and returned to the system. The operating economics of the continuous and stable production of gasoline and hydrogen offer great advantages in the achievement of maximum yield.

In the industrial production of nitric acid by the oxidation of ammonia over rhodium-platinum gauze catalysts the infrequent occurrence of an inactive gauze has prompted a number of investigations into their behaviour. This paper reports on a survey of the surface structure of individual gauzes in a catalyst pack and offers some indications towards the choice of optimum process variables.
