Structured Fe-ZSM-5 zeolite supported on silicon carbide (SiC) foam catalyst was develop and applied as the packed bed catalytic reactor (FBCR) to liquid phase wet peroxide oxidation (CWPO) of phenol under flow conditions. Fe catalysts were uniformly incorporated into ZSM-5 coatings using chemical vapour deposition (CVD). Fluid analysis FBCR performed by varying rate, showing transition type from plug continuous stirred tank at about 1 ml min−1. Systematic investigation CWPO within...
Hydraulic sandblasting perforation plays a crucial role in the fracturing and reconstruction of unconventional oil gas reservoirs.The jet nozzle is an essential part hydraulic tool.Insufficient penetration depth, caused by excessive distances, presents challenges during process.To overcome this, optimization design structure required to enhance efficiency.In this paper, computational fluid-dynamic model for conical-cylindrical nozzles has been elaborated.To further improve rock-breaking...

Bone-cuboid (a and b), spindle (c d) rhombic (e f) TiO<sub>2</sub> nanocrystals are all self-assembled into horizontal vertical ordered two-dimensional superlattices.
Abstract In this paper, rice husk (RH) was used as raw material to prepare white carbon black, and the key technological parameters of preparing black from RH were studied through single‐factor test, orthogonal experiment, response surface analysis. Meanwhile, characteristic also analyzed. Through experiment analysis, it confirmed that order factors affecting purity calcination temperature > alkali treatment time final pH surfactant. Based on optimization optimum for preparation follows:...
Nitrogen doped carbon quantum dots (N-CQDs) were synthesised by a hydrothermal method using ascorbic acid and valine as precursors. The as-synthesised N-CQDs characterised transmission electron microscopy, Fourier transform infrared spectroscopy, X-ray photoelectron UV−vis absorption spectra, well fluorescence spectrophotometer. results revealed that the as-prepared spherical shaped with an average diameter of 4 nm emitted bright blue photoluminescence yield approximately 4.8 %....
Abstract BACKGROUND Chemical vapor deposition (CVD) is a promising catalyst preparation method owing to high dispersion and small particles of metallic oxides. Besides, the ZSM‐5 zeolite membrane used treat volatile organic compounds (VOCs) due relatively contact efficiency, lower bed pressure drop mass transfer resistance than granular ZSM‐5, giving good stability metal catalysts. However, Cr modified prepared by CVD for trichloroethylene (TCE) catalytic oxidation was still not...
Telomere shortening is an accepted indicator of aging. Many studies have investigated association between leukocyte telomere length (LTL) and psychiatric disorders. Mental or psychological factors could be important cause irritable bowel syndrome (IBS). However, there are currently few research evaluating correlations LTL IBS.We examined associations IBS using quantitative polymerase chain reaction in independent cohorts, including 205 patients with 189 healthy controls. Furthermore, we...
We introduce the compound interest rate into continuous version of online leasing problem and discuss generalized model by competitive analysis. On one hand, optimal deterministic strategy its ratio are obtained; on other a nearly randomized is constructed lower bound for ratios proved Yao′s principle. With help numerical examples, theoretical results show that puts off purchase date diminishes uncertainty involved in decision making.
The CuCr mixed oxides catalysts supported on ZSM-5 zeolite (CuCr/ZSM-5) were synthesized via metal organic chemical vapour deposition (MOCVD) method for catalytic oxidation of trichloroethylene (TCE). SEM, XRD, BET, H2-TPR, NH3-TPD and XPS tested. active components dispersed uniformly over the surface zeolite. experimental results exhibited that CuCr/ZSM-5 best performance TCE with 90% at 338°C concentration C2Cl4 decreased compared Cu/ZSM-5 Cr/ZSM-5. possible reason is has superior...
To solve the problem of uneven dust cleaning in filter cartridges, a simple and easy-to-install “branch-type” nozzle structure was designed to improve efficiency. In this study, numerical simulations, range analysis methods, orthogonal experimental design, back-blowing experiments, powder experiments were conducted. By choosing uniformity as evaluation index for performance, with flow distribution coefficient A, length branch pipe B, outlet diameter main C factors, ignoring interaction...
It is well known that traffic flow presents multi-fractal characteristics at time scales. The aim of this study to test its multi-fractality spacial vehicular cellular automation (CA) model chosen as a tool get vehicle positions on single lane road. First, distribution checked, and spectrums are plotted. Second, analysis results show the width spectrum expresses ratio maximum minimum densities, height difference between left right vertexes represents relative size numbers sections with...
In order to depict the effect of driver’s memory on car-following behavior, a new kind model is proposed by using fractional differential equation in this paper. Its dynamic defined Caputo derivative. And derivative measurement memory. addition, discrete formulas position and velocity are given. The Optimal Velocity (OV) taken as an example introduce how get from ordinary model. simulation results show that Fractional Order (FOOV) more stable, it can avoid unrealistic acceleration values OV...
