Catalytic Study of Methanol-to-Olefins Conversion in Four Small-Pore Silicoaluminophosphate Molecular Sieves: Influence of the Structural Type, Nickel Incorporation, Nickel Location, and Nickel Concentration
TL;DR: In this article, the selectivity of four small-pore silicoaluminophosphate molecular sieves, including SAPO-34 (CHA), CHA, SALO-35 (LEV), ERI (ERI), and SAI-18 (AEI), toward light olefins in general and ethylene in particular has been investigated for the methanol-to-olefins reaction using gas chromatography.
Journal ArticleDOI
Electron spin resonance evidence for isomorphous substitution of titanium into titanosilicate timcm-41 mesoporous molecular sieve
TL;DR: In this paper, an upper limit for the substitution of titanium into a framework tetrahedral site is observed, which can be best explained as arising from trivalent titanium situated at a framework.
Journal ArticleDOI
Synthesis of Niobium Silicate Molecular Sieves of the MFI Structure: Evidence for Framework Incorporation of the Niobium Ion
A. M. Prakash,Larry Kevan +1 more
TL;DR: In this article, a new electron spin resonance (ESR) method was proposed to identify incorporation of transition metals into the framework of zeolite molecular sieves, and a novel niobium silicate molecular sieve of MFI was presented.
Journal ArticleDOI
Silicoaluminophosphate molecular sieves SAPO-11, SAPO-31 and SAPO-41: synthesis, characterization and alkylation of toluene with methanol
TL;DR: In this article, medium pore molecular sieves have been synthesized using di- n -propylamine as the organic template and they have been characterized by various methods such as X-ray powder diffraction, solid state MAS NMR spectroscopy, thermal analysis, chemical analysis and temperature programmed desorption of ammonia.
Journal ArticleDOI
Photoionization of N-Alkylphenothiazines in Mesoporous SiMCM-41, AlMCM-41, and TiMCM-41 Molecular Sieves
TL;DR: In this article, a series of mesoporous MCM-41 molecular sieves with variable amounts of framework titanium have been hydrothermally synthesized and used for PC{sub n} photoionization.
