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.

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 °C. The distillation column condenser is cooled by evaporating boiling liquid methane at −163 °C. The second stage has an evaporator with boiling ethylene at −106.7 °C. The final stage has an evaporator with boiling propylene at −25.9 °C. An effective plantwide control structure is developed and tested.

(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.

OPF-PPy scaffolds were synthesized using three different anions: naphthalene-2-sulfonic acid sodium salt (NSA), dodecylbenzenesulfonic acid sodium salt (DBSA), and dioctyl sulfosuccinate sodium salt (DOSS).  Scaffolds were characterized by ATR-FTIR, XPS, AFM, dynamic mech. anal., elec. resistivity measurements, and swelling expts.  OPF-PPy scaffolds were shown to consist of up to 25 mol % polypyrrole with a compressive modulus ranging from 265 to 323 kPa and a sheet resistance ranging from 6 to 30 × 103 Ohms/square.  In vitro studies using PC12 cells showed OPF-PPy materials had no cytotoxicity and PC12 cells showed distinctly better cell attachment and an increase in the percent of neurite bearing cells on OPF-PPy materials compared to OPF.  The neurite lengths of PC12 cells were significantly higher on OPF-PPyNSA and OPF-PPyDBSA.  These results show that elec. conductive OPF-PPy hydrogels are promising candidates for future applications in nerve regeneration.

Here we report the synthesis and characterization of PCLF-PPy and in vitro studies showing PCLF-PPy materials support both PC12 cell and dorsal root ganglia (DRG) neurite extension.  PCLF-PPy composite materials were synthesized by polymg. pyrrole in preformed PCLF scaffolds (Mn 7000 or 18,000 g mol-1) resulting in interpenetrating networks of PCLF-PPy.  Chem. compns. and thermal properties were characterized by ATR-FTIR, XPS, DSC, and TGA.  PCLF-PPy materials were synthesized with five different anions (naphthalene-2-sulfonic acid sodium salt (NSA), dodecylbenzenesulfonic acid sodium salt (DBSA), dioctyl sulfosuccinate sodium salt (DOSS), potassium iodide (I), and lysine) to investigate effects on elec. cond. and to optimize chem. compn. for cellular compatibility.  PCLF-PPy materials have variable elec. cond. up to 6 mS cm-1 with bulk compns. ranging from 5 to 13.5 % polypyrrole.  AFM and SEM characterization show microstructures with a root mean squared (RMS) roughness of 1195 nm and nanostructures with RMS roughness of 8 nm.  In vitro studies using PC12 cells and DRG show PCLF-PPy materials synthesized with NSA or DBSA support cell attachment, proliferation, neurite extension, and are promising materials for future studies involving elec. stimulation.
