โœฆ Synopsis

Cond~tions under winch pressure meats rmght be expected N porous catalyst pellets are mvesbgated and a pnon bounds on the rnagmtude of the pressure vanaaons are obtamed for the hm~tmg cases of bulk Muslon control and Knudsen dfluslon control Two previous mves@ations of the effect of neglectmg pressure grahents M calcula~ the effectiveness factor are compared critically, and a tlurd procedure IS suggested whxh avolds mconsistencies tierent III the earber work and appears to gave a better approxuaation

Adsorption isotherms for the system methane-nitrogen molecular sieves were made for temperatures between 123" and 295ยฐK. and pressures up to 8 5 atm. Constants for the Langmuir equation were obtained for the pure components. For the mixtures, constants for a modified Langmuir equation are presented.
