“…Apart from the literature discussed above, numerous papers concerning such topics as the estimation of heats of adsorption and entropy of adsorption by gas chromatography have been published (Cremer and Prior, 1951; Schay and Szekely, 1954;Toth and Graf, 1960;Carberry, 1961;Grubner, 1961b;Beebe and Emmett, 1961;Eberly, Jr., 1962;Petrova et al, 1962;Kiselev and Yashin, 1964;Eberly, 1964;Beljakova et al, 1964a,b;Piringer and Tataru, 1964; Kiselev et al, 1965a; Knozinger and Spannheimer, 1965;Spannheimer and Knozinger, 1966;Grab and Weinert, 1966; Gillespie et al, 1966;Masukawa et al, 1967;Amariglio, 19C8;Strand et al, 1968;Dimitrov et al, 1969). Excellent agreement has been found between the calorimetric method and the gas chromatographic method in the determination of heats of adsorption (Greens and Pust, 1958;Ross et al, 1962;Arita et al, 1965).…”
