Abstract: A gasoline boiling range hydrocarbon stream obtained by fractionation of overhead vapors from a delayed coker is treated for removal of organic silicon compounds prior to being processed in a desulfurizer and catalytic reformer. The stream is treated by a bed of material such as alumina, activated alumina or spent alumina-based desulfurizer catalyst at elevated temperature to reduce the level of organic silicon compounds. The organic silicon compounds, if not removed, are detrimental to desulfurizer and reformer catalysts. The organic silicon compounds are conventionally added to a delayed coker to control foaming.
