Chemical pathways for converting biomass into fuels produce compounds which key physical and chemical property data are unavailable. We developed an artificial neural network based group contribution method estimating cetane octane numbers that captures the complex dependence of fuel properties pure on structure is statistically superior to current methods.
Abstract All process designs are subject to uncertainties which make it impossible state with complete certainty that a design will work. This study presents measure of confidence considers the nature uncertainty and operability as whole. measure, called reliability, quantifies likelihood Detailed analyses presented for three special cases: random uncertainties, fuzzy both uncertainties. Practical procedures estimating reliability in these cases also presented.
Separating 2,3-butanediol (BDO) from fermentation broth is challenging. Water more volatile than BDO, so energy consumption for distillation high. One alternative a reactive extraction process. BDO in the reacts with an aldehyde or ketone to form insoluble dioxolane, which can be decanted broth. The dioxolane subsequently heated water steam, resulting decomposition of into and ketone, are separated recover recycling. Although variations this process have been demonstrated, no information on...
A simple, inexpensive catalyst system (Amberlyst 15 and Ni/SiO2 -Al2 O3 ) is described for the upgrading of acetone to a range chemicals potential fuels. Stepwise hydrodeoxygenation produced ketones can yield branched alcohols, alkenes, alkanes. An analysis these products provided, which demonstrates that this approach provide product profile valuable bioproducts biofuels.
Converting biomass into jet fuel involves more than the core chemical process. The overall process includes logistics of harvesting and transporting biomass, handling preparing material for processing, processing disposal waste. All these activities contribute to cost. Controlling cost developing efficient chemistry. Choice feedstock also has a significant impact on economics. We consider conversion paper from municipal solid waste as production diesel. Paper significantly higher cellulose...
Uranium hydride is commonly used to store hydrogen or its isotopes in a solid state. The Self-Assaying Tritium Accountancy and Containment Unit for ITER (STACI) 5.2-kg bed of depleted uranium (dU) capable holding up 33 mol isotopes. This paper summary data analysis past experimental campaigns with STACI, the aim describing kinetics thermodynamics hydriding process. Computed tomography imaging was performed on STACI both before after campaign, high degree swelling observed dU. Literature...
Separation technologies currently used in U.S. manufacturing industries are estimated to account for more than 20% of plant energy consumption. However, accurately determining the impact new separation technology solutions can sometimes be difficult, especially when evaluating a slate candidate technologies, each which has its own performance, demand, and capital cost. In these cases, typical approach is assess by collecting performance cost information then using that develop...
