	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 = {Zinc contg. org. materials were synthesized using dairy wastewater and solid zinc waste derived from zinc nitrate with the goal of obtaining biodegradable, slow release, micronutrient contg. fertilizers.  The developed synthesis procedure involved heating at mild 55 {\textdegree}C temp., followed by pH adjustment to 7, pptn., and drying.  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.
