A new method that is simpler and more accurate than the author's previous presented for estimating f(E) k0(E) in distributed activation energy model. It utilizes at least three sets of experimental data obtained different heating rates, a. The Arrhenius plot ln(a/T2) vs 1/T (T: temperature) same conversion level allows determination both E k0 by introducing an approximation. k0(E), unique to reaction system concern, can then be changing level. validity accuracy this are shown through model...
5-Hydroxymethylfurfural (HMF) was effectively produced from monosaccharides in a microreactor. A biphasic reaction system employed to achieve the immediate extraction of HMF and suppress overreaction. microreactor utilized ensure that occurred under segmented flow enhance efficiency. Through many attempts using phosphate buffer saline (PBS) as phase 2-sec-butyl phenol (2BP) phase, favorable conditions were determined. By PBS with pH 2.0 2BP at volume ratio 3 PBS, 80.9 mol % fructose 75.7...
5-Hydroxymethylfurfural (HMF) was synthesized from monosaccharides by a biphasic reaction system using microreactor. The realized an immediate extraction and stabilization of product HMF, which further degrades under the conditions. Segmented flow utilized for efficient reaction-extraction tool. effect ability evaluated based on phase/reaction phase partition coefficient HMF. A Lewis acid catalyst introduced to overcome obstacle reaction, clarified as isomerization glucose fructose, improved...
Phase separation of poly(vinylidene fluoride) dimethylformamide solution was induced by the penetration water vapor, and porous membrane formed. As humidity in gas phase increased, morphology changed order dense, (cellular), lacy-like structures. At higher condition, spherical bead structure observed, which is likely to be crystalline spherulite. With increase initial polymer concentration, less pores were formed case lower 20%, whereas more distinguished structures 40%. The obtained...
The isothermal phase diagram for poly(vinylidene fluoride)/dimethyl formamide/water system was derived. binodal and spinodal were calculated based on the Flory–Huggins theory approximately in agreement with experimental data of cloud points. crystallization line also obtained according to melting point depression. Mass transfer three components during membrane formation by precipitation from vapor has been analyzed. During this process, separation polymer solution is induced penetration...
Two types of self-gravitating particle solutions found in several theories with non-Abelian fields are smoothly connected by a family non-trivial black holes. There exists maximum point the hole entropy, where stability changes. This criterion is universal, and changes follow from catastrophe-theoretic analysis potential function defined entropy.
Fast mixing is an essential feature of a microreactor. This study reveals the critical role microscopic fluid incorporation on fast chemical reactions in The vortices microreactor produce tiny segments, and these segments into surrounding triggers reactions. selectivity highly depends type segment incorporated fluid. Microreactor operations that consider incorporative can achieve better reaction results, even with slow mixing. For example, tee mixer showed performance vertical confluence...
Polysulfone (PSf) membranes were prepared by the immersion precipitation method from casting solution of PSf and a water-soluble polymer, poly(vinyl pyrrolidone) (PVP), in dimethylacetamide. The effect molecular weight PVP on phase separation rate during porous membrane formation was investigated light scattering method. plots scattered intensity against angle showed maxima, which indicated that occurred spinodal decomposition. structure growth remarkably enhanced addition with lower due to...
A new method was developed for extracting a great deal of brown coal in several conventionally used solvents at room temperature. The pretreated with hydrogen peroxide liquid phase 60 °C 2 h to break some weak covalent bonds and introduce oxygen functional groups. extracted by binary low-molecular-weight alcohol (methanol, ethanol, 1-propanol, or 2-methyl-1-propanol) an aromatic compound (1-methylnaphthalene, 2-methylnaphthalene, m-xylene, phenol) different mixing ratios temperature the...
