Abstract
Hydrocarbon conversion processes having a susceptibility to coke formation on the internal surfaces of processing equipment are improved by inhibiting the formation of coke with the use of a glass bead treatment for the metal surfaces. After treating with ordinary glass bead cleaning methods, metal surfaces are found to inhibit coke formation. The glass bead treatment is easily performed and, therefore, offers advantages over other chemical treatments for the deposition of silica on reactor internals.
