Thermophysical properties of biofuel components derived from biomass

Nduli, Mbalenhle B. January 2016 (has links)
Submitted in fulfillment of the academic requirements of the degree of Master of Technology, Durban University of Technology, Durban, South Africa, 2016. / The thermophysical properties of the binary mixtures containing biofuel components derived from biomass were determined. Experimental densities, speed of sound, and refractive indices for the binary mixtures (methanol or 1-ethyl-3-methylimidazolium acetate [EMIM][OAc] + furfural or furfuryl alcohol ) were measured at T = (298.15, 303.15, 308.15, 313.15 and 318.15) K. From the experimental data, excess molar volume, E m V , isentropic compressibility, s  , molar refractions, R, and deviation in refractive index, Δn, were calculated. The excess molar volumes were found to be negative for all systems studied. The isentropic compressibility were found to be both positive for the whole composition and temperature range and increases slightly with increasing temperature. The deviation in refractive index was positive over the whole composition range. The obtained values of excess molar volumes and changes of refractive index on mixing were satisfactorily correlated by the Redlich–Kister equation. The Lorentz–Lorenz equation was applied to predict the density and calculate the excess molar volume of the binary mixtures. / M

A Probabilistic Inventory Analysis of Biomass for the State of Texas for Cellulosic Ethanol

Gleinser, Matthew A. 16 January 2010 (has links)
Agricultural and forestry wastes for the use of creating cellulosic ethanol were inventoried for each county in Texas. A simple forecast was created for each of the agricultural wastes and then a multivariate empirical distribution was used to simulate the range of biomass available by county and district. The probability that a district could support a 25, 50, 75, or 100 million gallon cellulosic ethanol plant is estimated from the Monte Carlo simulation results. Biomass in Texas is concentrated in the Northern and Eastern areas of the state. The areas of South and West Texas have little to no biomass available to use for cellulosic ethanol. The North East, South East, and Upper Coast districts include forestry waste that increase the amount of available biomass. With 100 percent certainty the North East and South East districts can support four 100 million gallon cellulosic ethanol plants each. The research found that there is more than enough biomass to support numerous cellulosic ethanol plants in Texas, and decision makers can use the results of this study to identify regions of low and high risk for available biomass from agricultural and forestry waste.
