Abstract Experiments of pressure effects on gas holdup and bubble size in slurry columns at 5.6 MPa velocities up to 45 cm/s indicate that the increases with an increase pressure, especially high concentration. At ambient a higher solids concentration significantly lowers over entire gas‐velocity range, while MPa, effect is relatively small above 25 cm/s. An empirical correlation was developed based these data those literature predict wide range operating conditions. analysis flow...
The direct synthesis of dimethyl carbonate (DMC) from CO2 and CH3 OH was achieved at room temperature with 74 % conversion in the presence an imidazolium hydrogen ionic liquid ([Cn Cm Im][HCO3 ]). Experimental theoretical results reveal that [Cn ] can transform quickly into a adduct, which serves as effective catalyst dehydrant. Its dehydration ability is reversible. energy barrier rate-determining step for DMC only 21.7 kcal mol-1 . be reused easily without significant loss its catalytic...
Abstract We report herein a gold and palladium sequential catalysis system to access furan‐fused nine‐membered heterocycles in high efficiency enantioselectivity. In this one‐pot procedure, easily accessible enynamides undergo cyclization generate azadienes situ that participate enantioselective formal [5+4] cycloaddition with vinyl ethylene carbonates. Conformation‐controlled highly diastereoselective derivatizations of these medium‐sized rings, coupled oxidative furan cleavage, have...
A direct route for the synthesis of cyclic carbonates from olefins and CO<sub>2</sub> has been achieved by using imidazolium hydrogen carbonate ionic liquids as bifunctional catalysts in absence a solvent.
Synthesis of cyclic carbonates from CO<sub>2</sub> and epoxides at room temperature in the absence a solvent has been achieved by using Al-salen complexes as catalysts imidazolium hydrogen carbonate ionic liquids cocatalysts.

Volumetric gas−liquid mass-transfer coefficients are investigated in bubble columns under high-pressure and moderate-temperature conditions by utilizing an oxygen desorption method. The concentration the liquid phase, water or Paratherm NF heat-transfer fluid, is monitored with a optical fiber probe. study covers operating up to pressures of 4.24 MPa temperatures 92 °C. superficial gas velocities vary 40 0.89 cm/s, respectively. Experimental results show that system pressure, temperature,...
Summary A porcine genome linkage map composed of 194 microsatellite markers was constructed with a large‐scale White Duroc × Erhualian resource population. The marker order on this consistent the USDA‐MARC reference except for two SSC3, SSC13 and SSCX. length sex‐averaged (2344.9 cM) nearly same as that NIAI map. Highly significant heterogeneity in recombination rates between sexes observed. Except SSC1 SSC13, female autosomes had higher average than male autosomes. Moreover, pseudoautosomal...
With the rapid development of industry, heat removal and management is a major concern for any technology. Heat transfer plays critically important role in many sectors engineering; nowadays utilizing nanofluids one relatively optimized techniques to enhance transfer. In present work, facile low-temperature solvothermal method was employed fabricate SnO2/reduced graphene oxide (rGO) nanocomposite. X-ray diffraction (XRD), thermogravimetric analysis (TGA), photoelectron spectroscope (XPS),...
There is immense potential for the industrial application of microbubble technology in bubble column to intensify multiphase flow mass transfer process. In this work, characteristics (bubble size distribution, gas holdup, specific interfacial area, and volumetric coefficient) were investigated systematically a microbubble-dominated column. A key process flue desulfurization, ammonium sulfite oxidation, was selected as gas–liquid contact reaction. Experiments performed laboratory scale (16 L)...
