Optimizing the number, distribution, and accessibility of Brønsted acid sites in zeolite-based catalysts is of a paramount importance to further improve their catalytic performance. However, it remains challenging to measure real-time changes in reactivity of single zeolite catalyst particles by ensemble-averaging characterization methods. In this work, a detailed 3D single molecule, single tur...
results the batch kinetics experiments showed that nom adsorption by the adsorbents followed the pseudo-second order model. results showed that the acidic ph is optimum for adsorption of nom by smz. conclusions the findings of this study show that natural zeolite modified with sodium dodecyl sulfate, as a cationic surfactant, is a promising adsorbent for removal of nom. materials and methods in...
In order to reduce the current costs associated with carbon capture technologies, novel materials such as zeolites and metal-organic frameworks that are based on microporous networks are being studied. We have developed a GPU code that can characterize and screen a large database of zeolite structures and help identify the most e cient structures for carbon capture. The interactions between the...
an experiment with 300 one-day old ross male broiler chicks was conducted to determine the effects of glauconite and zeolite on the broiler's performance, tibia bone and blood characteristics. five experimental treatments [control, glauconite (2 & 4 percent), and zeolite (2 & 4 percent)] were used in a completely randomized design with 4 replicates. during the experiment weight gain, feed ...
The aim of this study was to determine the effect of natural zeolite (commercial preparation with 80% of clinoptilolite) on counts of different physiological groups of bacteria i.e. sulfide-producing, faecal and total coliform, mesophilic aerobic and anaerobic, and thermophilic bacteria in pig slurry. Zeolite was spread daily directly over partially slatted floor in a dose of 0.4 kg/1 m 2 durin...
—A machine learning approach is applied to classify zeolite crystals according to their framework type. The Zeolite-Structure-Predictor is introduced based on the Random Forest algorithm. Zeolites structural data from the Inorganic Crystal Structure Database (ICSD) are used to train the model. The ZSP uses sixteen attributes including topological descriptors obtained with statistical geometry a...
Owing to the recent progress in the area of hardware and software of the pulsed field gradient NMR technique, molecular transport in real-life zeolite systems, such as zeolite beds and particles of formulated fluid catalytic cracking (FCC) catalysts, can be investigated in detail. These studies have revealed a number of important features of molecular transport in zeolites, which are reviewed i...
effect of natural zeolites and nano-zeolite on gut flora, tibia bone characteristics, blood parameters and performance of broilers investigated with 336 male ross 308 broilers chicks allocated to seven treatments with four replicates and 12 chicks per each. experimental treatments were control (no zeolite supplemented), natural zeolite (0.5, 1 and 1.5 percent) and nano-zeolite (0.5, 1 and 1.5...
A novel utilization method of filter residue from the preparation process of zeolite-based catalysts was investigated. Y zeolite and a fluid catalytic cracking (FCC) catalyst were synthesized from filter residue. Compared to the Y zeolite synthesized by the conventional method, the Y zeolite synthesized from filter residue exhibited better thermal stability. The catalyst possessed wide-pore dis...
A quartz crystal microbalance (QCM) was utilized to measure the water content in ethanol. For the improvement of measurement sensitivity, the QCM was modified by applying zeolite particles on the surface with poly(methyl methacrylate) (PMMA) binder. The measurement performance was examined with ethanol of 1% to 5% water content in circulation. The experimental results showed that the frequency ...
