Inhibition of popcorn polymer growth by treatment with a sulfur-containing compound. The sulfur-containing compound can be added to organic material from which popcorn polymer is formed, or applied to extant popcorn polymer.

Inhibiting popcorn polymer formation with sulfur-containing compounds

Zeolites washed with aqueous solutions or water to exhibit pH in the range of 9.4 to 10.0 and preferably 9.6 to 10.0 which can be converted to reforming catalysts with enhanced activity, selectivity and activity maintenance. Also processes for washing the zeolite to the target pH range and processes for using catalysts made with the washed zeolite to reform naphtha feeds.
