Abstract

A formula to calculate theminimum quantity of material necessary to poison or promote a supported metal catalyst, based on theoretical criteria of poisoning range, has recently been proposed (R.W. Joyner and J.B. Pendry, Catal. Lett. 1 (1988) 1). This paper reports experimental tests of this formula for chlorine, sulphur and iodine poisoning of a Pd/C catalyst for the hydrogenation of cyclohexene. For chlorine and sulphur a significant excess of poison is required compared to the estimate, while the results for iodine are in excellent agreement with the calculation. The theory is also compared with a number of literature studies of sulphur poisoning and appears to have wide validity.
