Effects of Gel Preparation Conditions on the Crystallization of SAPO-11 Molecular Sieves
Using a combination of XRD, 27Al and 31P MAS NMR, SEM, TEM, N2 low-temperature adsorption–desorption, and IR spectroscopy of adsorbed pyridine, the effects of gel preparation conditions on the properties of the SAPO-11 molecular sieves crystallized from the gels were investigated. It was demonstrated that the crystal morphology and the characteristics of secondary pores of SAPO-11 molecular sieves can be controlled by adjusting the sequence in which the initial components are mixed during gel preparation. The synthesized micro–mesoporous SAPO-11 samples exhibited high selectivity in the hydroisomerization of n-hexadecane.
期刊介绍：
Petroleum Chemistry (Neftekhimiya), founded in 1961, offers original papers on and reviews of theoretical and experimental studies concerned with current problems of petroleum chemistry and processing such as chemical composition of crude oils and natural gas liquids; petroleum refining (cracking, hydrocracking, and catalytic reforming); catalysts for petrochemical processes (hydrogenation, isomerization, oxidation, hydroformylation, etc.); activation and catalytic transformation of hydrocarbons and other components of petroleum, natural gas, and other complex organic mixtures; new petrochemicals including lubricants and additives; environmental problems; and information on scientific meetings relevant to these areas.
Petroleum Chemistry publishes articles on these topics from members of the scientific community of the former Soviet Union.
