	abstract = {AbstractA complete separation scheme has been designed for the effluent of a high-pressure ethanol-to-butanol catalytic reactor, producing 250,000 tonnes of n-butanol per year. The effluent contains water, hydrogen and a diverse range of C2-C4 oxygenates: unconverted ethanol, n-butanol, acetaldehyde, ethyl acetate, and acetal. Fundamental phase equilibrium relationships suggested use of conventional, extractive, and heterogeneous azeotropic distillation units to perform the separations. All reactor effluent species exit the separation process at mole purities of at least 99\%. Separation costs are estimated to range from 9.0 to 10.6 MJ/kg n-butanol, which is comparable with the separation costs of n-butanol obtained from established acetone-butanol-ethanol (ABE) separation process.

	abstract = {AbstractProviding refrigeration at very low cryogenic temperatures requires the use of several stages of compression refrigeration with progressively lower boiling point refrigerants in the various stages. The cascade of cycles ultimately rejects heat to cooling water, but the working fluid at each stage removes heat from a lower-temperature source and rejects this heat plus the compressor work in that stage to a higher-temperature sink. The design of these systems appears to be only qualitatively discussed in the literature, and no discussion of their plantwide dynamic control has been found.
This paper presents a quantitative design of a three-stage compression refrigeration process that uses methane, ethylene and propylene as the working refrigerant fluids in the three stages. Heat is removed in the condenser of a cryogenic distillation column separating carbon monoxide and methane. The bubble-point temperature of carbon monoxide at 13.9 bar is -158 {\textdegree}C. The distillation column condenser is cooled by evaporating boiling liquid methane at -163 {\textdegree}C. The second stage has an evaporator with boiling ethylene at -106.7 {\textdegree}C. The final stage has an evaporator with boiling propylene at -25.9 {\textdegree}C. An effective plantwide control structure is developed and tested.

The resulting solid materials were characterized using wt. anal., thermogravimetric anal. (TGA), X-ray diffraction (XRD), and Fourier transformed IR spectroscopy (FTIR).  Higher wastewater-to-zinc nitrate ratios of 1:1/5 yielded amorphous materials with no inorg. zinc compds. detected.  TGA anal. showed very complex thermal behavior due to the large amt. of orgs. present while FTIR anal. suggested the presence of both coordinated and uncoordinated carboxylic acid and ester groups.  The developed process can have a variety of applications in recovering Zn from waste sources, such as tire crumb, while returning this valuable micronutrient into soil as a slow release biodegradable fertilizer.

Plasma was generated in a quartz tube with the ambient air used as a feed gas for the reactor.  The performance of the reactor was evaluated according to the ozone amt. produced both in the gas and liq. phase, as well as the overall decompn. efficiency of 2-naphthol.  The decompn. kinetics, as well as the intermediary reactive products of 2-naphthol decompn. were detd. using the combination of high performance liq. chromatog. with UV detection (HPLC/UV), Fourier transform IR spectroscopy (FTIR), and gas chromatog./mass spectroscopy (GC/MS) analyses.  The overall effectiveness of the process was established according to the degree of total org. carbon (TOC) mineralization, while toxicity tests were performed using Daphnia magna.  Ozone prodn. (i.e., its concn. in the gas phase), ranged between 0.39 and 1.52 mg L-1 when varying the discharge power between 5-33 W.  The decompn. efficiency of 2-naphthol reached 98.6\% in 6 min at 33 W based on HPLC measurements.  FTIR and GC/MS analyses revealed that degrdn. intermediates consisted mostly of oxygen functional group contg. compds., such as carboxylic acids.

Crystallinity of the composite material was analyzed via XRD and both CdSe and CdS were detected within the material at all deposition conditions of temp. and SeS2O2-6 - chalcogenization - exposure time.  A complex surface speciation was obtained using XPS anal.  Formation of the protonated amide species was obsd. in combination with the adsorbed SO2-4 on the surface of the polymer confirming that SeS2O2-6 and its decompn. products hydrolyzed to form cadmium chalcogenides and H2SO4.  A significant red shift in UV-vis spectrum was obsd. with the increasing chalcogenization time of PA, whereas Cd2+ soln. temp. had very little effect on the apparent thickness and the optical properties of the composite materials.  SEM surface anal. revealed sub-micron particles deposited on top of the PA-CdSe-CdS composite materials in continuous overlapping films, showing a possible dual crystal growth mechanism.

The av. diam. of the fibers, their morphol., basis wt., thickness, and resulting media solidity were investigated.

(oxalate) reductive dissoln.  Empirical relations between dissoln. rate and pH revealed that suspensions of 8 nm hematite exhibit between 3.3- and 10-fold greater reactivity per unit mass than suspensions of 40 nm particles across all dissoln. modes and pH, including circumneutral.  Complementary suspension characterization (i.e., sedimentation studies and dynamic light scattering) indicated extensive aggregation, with steady-state aggregate sizes increasing with pH but being roughly equiv. for both primary particles.  Thus, while the reactivity difference between 8 and 40 nm suspensions is generally greater than expected from sp. surface areas measured via N2-BET or estd. from primary particle geometry, loss of reactive surface area during aggregation limits the certainty of such comparisons.  Probably the relative reactivity of 8 and 40 nm hematite suspensions is best explained by differences in the fraction of aggregate surface area that is reactive.  This scenario is consistent with TEM images revealing uniform dissoln. of aggregated 8 nm particles, whereas 40 nm particles within aggregates undergo preferential etching at edges and structural defects.  Ultimately, comparably sized hematite aggregates can exhibit vastly different dissoln. activity depending on the nature of the primary nanoparticles from which they are constructed, a result with wide-ranging implications for iron redox cycling.
