The rate of attrition of a catalyst rample, of a single particle size, can be expressed by a simple function of initial diameter and time. The initial rate is a function of initial diameter, whereas the decrease in attrition rate of a catalyst of a given size as it ages depends only on time. The at
Adsorption of poly(5-tert-butylperoxy-5-methyl-1-hexen-3-yne-co-maleic anhydride) and poly(styrene-co-maleic anhydride) on the various ultrafine powders (TiO 2 , ZnO, Al 2 O 3 , CaCO 3 , aerosil, and quartz powder) was studied. Plateau adsorption amount per unit surface of adsorbent ( a s ) decrease
