✦ Synopsis

The feasibility of using steam as a desorbent for n-paraffins adsorbed on Linde Molecular Sieve 5-A was investigated. The feedstock was kerosene obtained from Gujrat Refinery and experiments were conducted at two different temperatures for a fixed feed rate. Desorption with steam was carried out repeatedly for a number of cycles without intermediate reactivation. Substantial decrease in adsorption capacity of the sieves was observed. On reactivation, the sieve regained its original capacity. Performance of steam was compared with n-pentane as desorbent. More work is required before steam can be recommended as a possible desorbent.
