Differential and Integral Heats of Sorption. AH or AH can indicate relative selectivities of zeolites for water, and hence their relative value [Pg.118]

On the other hand, the differential heat of sorption of dry cellulose (i. e., the heat evolved if 1 g water is sorbed by an infinite quantity of cellulose) should be equal for all specimen. It is actually borne out by experiments that the integral heat of sorption and the sorption ratio of various specimen are nearly proportional to each other, but that the differential heat of sorption of native and regenerated cellulose is equal The experimental data further reveal that the percentage of crystalline matter is greatest in native fibres and markedly lower in regenerated ones. In the latter, it shows but very small variations and seems to be constant in first approximation. [Pg.539]

Related attempts had been made to calculate integral sorption heats of CO2 on all materials investigated, e.g., on D 47/2, by means of eq. (23) where the isosteric sorption heats (differential quantities) were used to calculate integral quantities over defined ranges of sorption-phase concentration, n, e.g., between its limits n = 0 and n = n.
