Silicalite-1 formation in acidic medium: Synthesis conditions and physicochemical properties
نویسندگان
چکیده
Zeolites are the catalytic materials that widly applied in processing of conventional and renewable fuels chemicals. The present study provides a comprehensive analysis factors controlling acidic medium synthesis high silica silicalite-1 zeolite. effect various sources (TEOS, fumed colloidal silica) alkali metal cations (Na K) on formation is studied. efficiency different types seeds (micron-sized, nanosized, amorphous precursor) crystal growth kinetics size formed under conditions also investigated. Further, zeolite crystallization acidic, neutral, basic compared. obtained highly crystalline samples used to compare physicochemical properties zeolites synthesized medium. Thus, crystallinity, thermal stability, local order (2–12) pH range evaluated.

simulation and experimental studies for prediction mineral scale formation in oil field during mixing of injection and formation water
abstract: mineral scaling in oil and gas production equipment is one of the most important problem that occurs while water injection and it has been recognized to be a major operational problem. the incompatibility between injected and formation waters may result in inorganic scale precipitation in the equipment and reservoir and then reduction of oil production rate and water injection rate. ...
MULLITE SYNTHESIS AND FORMATION FROM KYANITE CONCENTRATES IN DIFFERENT CONDITIONS OF HEAT TREATMENT AND PARTICLE SIZE
The process of mullitization of kyanite concentrate was studied at different conditions of heat treatment (1400– 1600 °C and 0.5 – 3.5 hours) and particle size of raw materials (38-300 ?m). Kyanite concentrate was obtained fromore-dressing of kyanite deposits of Mishidowan-Bafgh region at 100 km northeastern part of Yazd. The results ofmicrostructure (shape, distribution and size of the grains)...
متن کاملSynthesis of nanosized TiO2 powder by Sol-Gel method in acidic conditions
The preparation of nano-sized TiO2 by titanium tetraisopropoxide (Ti(OiPr)4) via sol-gelmethod using acid as a catalyst is investigated and the optimized conditions concerning theproportional amount of acid, water, alcohol is established by XRD and SEM. The effect ofcalcination temperature on phase transformation of TiO2 (rutile, anatase and brookite) wasdetermined by XRD. The smallest grain si...
متن کاملSynthesis, physicochemical properties and antimicrobial activity of mono-/dinitroxyl amides.
Two comparative sets of mono-/dinitroxyl amides were designed and prepared. The novel TEMPO and/or PROXYL derivatives were fully characterised and their spin, redox and antimicrobial properties were determined. Cyclic voltammetry revealed (quasi)reversible redox behavior for most of the studied radicals. Moreover, the electron-withdrawing substituents increased the oxidation potential of nitrox...
متن کاملCationic Surfactants from Arginine: Synthesis and Physicochemical Properties
The present invention concerns the preparation of cationic surfactants derived from the condensation of an acid chloride, preferably a fatty acid with a number of carbon atoms 8, 9 and 14 with esterified amino acids, preferably basic-type amino acids, like (L)-arginine. The method comprises a first step in which the esterification of the amino acid with an alcohol is performed and a second step...
