The synthesis of glutamic acid from propane
… was first, the production of glutaric acid from propane, via chlorination, followed by the amination of glutaric acid to form the amino acid - glutamic acid. The purpose of this thesis, therefore, was to develop a practical method for the synthesis of glutamic acid, starting with propane, and …

An Investigation of Low Temperature Direct Propane Fuel Cells
… the investigation of a low temperature direct propane fuel cell (DPFC). Modeling included a parametric study of a direct propane fuel cell using computational fluid dynamics (CFD), specifically FreeFem++ software. Polarization curves predicted by the CFD model were used to understand fuel cell …

The Phase Behavior of Heavy Oil and Propane Mixtures
The phase behavior of propane diluted bitumen was mapped from temperatures between 20 and 180°C and pressures up to 10 MPa. Both vapor-liquid (VL) and liquid-liquid (LL) regions were observed. High pressure micrographs demonstrated that the heavy phase (a pitch phase) transitioned from a glass to a …

Nanocomposite catalysts for soot combustion and propane steam reforming
… (NiAl20 4), Re and V has been synthesized for propane steam reforming. Nickel aluminate nanocrystals with various Ni/Al molar ratios were prepared by chemical co-precipitation. They were pretreated in H2 prior to propane steam reforming to obtain highly dispersed Ni species. The Al in nickel …

Evaluation of Propane-Butane Mixtures as Solvent in ES-SAGD
… the least expensive available solvent is propane, but it is not as effective as heavier solvents. So, mixtures of propane and butane are evaluated in the study to see if we can find a solvent mixture for SA-SAGD that can nearly match the performance of pure butane, but at a lower cost. …

Thermodynamic Formation Conditions for Propane Hydrates in Equilibrium with Liquid Water
… for hydrate formation conditions of pure propane in the presence of liquid water is important to avoid flow assurance issues in processing, storage and transportation of liquefied petroleum gas, as well as modeling hydrate based separation processes involving type II hydrates. Experimental …

Photophysical properties of pyrene, 2,7 diazapyrene and 1,3-bis(β-naphthyl)propane.
The luminescence properties of Van Der Waals' dimers and clusters of pyrene and diazapyrene have been investigated. Excimers, dimeric species which are associative in an excited electronic state and dissociative in their ground state, have long been established and play an important role in many …
