The acidity of catalysts and their catalytic activity were generally enhanced with increasing exchange or pretreatment. But excessive decationation or de-alumination caused deactivation due to partial destruction of the crystalline lattice. As seen in Figs. 10 and 11, experimental data shows good linear relations between log ko, the zero order rate constant, and Ho. This linearity is theoretically supported by assuming a surface reaction mechanisms analogus to homogenous acid catalysis. The line slopes were less than unity in absolute value and varied somewhat with the respective catalyst as seen in Table 1, suggesting a proton mobility characteristic for zeolite. The application of Ho to solid acid catalysis was considered to be available by supposing a correction of pKa of indicators suitable to the surface or intracrystalline state.
