The steam dealkylation of toluene to benzene was tested on rhodium supported on 15 different supports, mostly silica and chromia with or without alkali additive. Best stability was obtained with potassium-promoted ..gamma..-chromia, which lost 0.15%/hr activity at 461/sup 0/C and 0.77%/hr activity at 576/sup 0/C in 45-50 hr runs. Generally, catalysts prepared by adsorption from excess solution were more stable than catalysts prepared by the incipient wetness method.
