Steady state distillation calculations: An investigation of computer techniques and an examination of results
This work has been divided into two parts. The first is concerned with methods of computation suitable for use with digital computers for distillation problems with one feed and two product streams. Two methods were ...
Vapor-liquid equilibria in the system hydrogen-nitrogen-carbon monoxide
Vapor-liquid equilibrium compositions for the system hydrogen-nitrogen-carbon monoxide were determined at -310°F, and -280°F and -240°F from 300 psig to the critical. PVT data for hydrogen were fitted to the ...
Effects of the decay of sulfur-35 on some electrical properties of cadmium sulfide semiconducting films
The vacuum behavior of radioactive and non-radioactive semiconducting films of CdS has been studied as a function of time in order to determine the effect of radioactive doping. Radioactive films containing S35 were made ...
Low temperature vapor-liquid equilibrium in light hydrocarbon mixtures: Methane-ethane-propane system
Experimental equilibrium data have been determined for 175 mixtures of methane, ethane, and propane. The investigation included temperatures from 50°F to -200°F and pressures up to the critical. A vapor recycle ...
A study of alumina silicon fluoride combinations as hydrocarbon conversion catalysts
The purpose of this work was to study the influence of certain variables in the preparation of an alumina-silicon-fluoride complex on its behavior as a cracking catalyst.
The effect of shear on the thermal conductivity of non-Newtonian fluids
This work considers the effect of shear on the thermal conductivity of non-Newtonian fluids. These fluids display a variation of viscosity as a function of shear rate, and this study determines whether the thermal conductivity ...
Selective hydrogenation of 1,3-butadiene in 1-butene over alumina supported palladium and palladium/copper catalysts
Copper addition to palladium increases both activity and selectivity in the selective hydrogenation of 1,3-butadiene to n-butenes. The bimetal catalyst (Cu/Pd:2/1(atomic)) hydrogenates the diene to virtually 100% conversion ...
EXPLICIT FINITE DIFFERENCE SCHEMES BASED ON THE MODIFIED METHOD OF CHARACTERISTICS AND THEIR APPLICATION TO THE MISCIBLE DISPLACEMENT PROBLEM
A class of convection-diffusion parabolic boundary value problems is considered in this study. When convection dominates over diffusion, the solutions of such problems exhibit an almost hyperbolic behavior. Initial conditions ...
EFFECTIVE DIFFUSIVITIES IN CHAR PARTICLES (DIFFUSION, FAST FOURIER TRANSFORM, PYROLYSIS, COAL, FLUIDIZED BED)
Illinois #6, Illinois #5, Pittsburgh #8 coal and Texas Lignite particles of size range 150-16 mesh were pyrolyzed at a heating rate of 3.8 K/min up to 900(DEGREES)C. A stainless steel annular fluidized bed reactor yielded ...
