Occlusion of hydrocarbons by chabazite and analcite

Structure–deactivation relationships in zeolites during the methanol–to-hydrocarbons reaction: Complementary assessments of the coke content

“…As previously said, Barrer and Milton [13,[43][44][45][46] during 1940s' and 1950s' reported for the first time the synthesis of zeolites using low-temperature hydrothermal methods. This approach boosted the interest in both zeolite synthesis and their application, resulting in the commercialization of adsorbents based on zeolites A and X in 1948 [25].…”

Adsorption of 1-n-Alkyl Pyridinium Bromides by Montmorillonite

“…however, are additive for each atom in the ion. Barrer and Ibbitson (1944) have in fact shown that for the adsorption of straight chain aliphatic hydrocarbons by chabazite, a cubic lattice zeolite type silicate, the heat of adsorption increases linearly with the size of the molecule and for molecules containing more than eight carbon atoms can attain a magnitude similar to that for a covalent bond. The adsorption of the hydrocarbon must be due predominantly to dispersion forces similar to those operating in the present instance between the aliphatic chain and the alumino-silicate surface.…”

Zeolites and related sorbents with narrow pores for CO2 separation from flue gas

“…[8][9][10][11][12][13][14][15] Their work focused mainly on natural zeolites, such as chabazite, 8,10,11,16 mordenite, 10,13,15 and analcite. 17,18 Their studies included size or interaction based selectivities exhibited by zeolites on different sorbates. In addition, they were one of the rst to study diffusion of different small organic and inorganic gas molecules in zeolites.…”
