TL;DR: Optimized intermolecular potential functions have been determined for hydrocarbons through Monte Carlo simulations of 15 liquids: methane, ethane, propane, n-butane, isobutane, NOPANE, isopentane, NEOPENTANE, cyclopentANE, N-hexane, 1-butene, cis-and trans-2-butenes, and benzene as discussed by the authors.
Abstract: Optimized intermolecular potential functions have been determined for hydrocarbons through Monte Carlo simulations of 15 liquids: methane, ethane, propane, n-butane, isobutane, n-pentane, isopentane, neopentane, cyclopentane, n-hexane, 1-butene, cis- and trans-2-butene, isobutene, and benzene. To achieve high accuracy, 12 unique group types were identified and their associated Lennard-Jones parameters were established. The average deviation from experiment for the computed densities and heats of vaporization is 2% and trends for isomeric series are reproduced. Conformation results were also obtained for five liquids and revealed no condensed-phase effects on the conformer populations. Structural analyses focus on trends as a function of chain length and branching of the monomers.

TL;DR: In this paper, the coefficients of these short forms for the equations of state have been fitted for the fluids acetone, carbon monoxide, carbonyl sulfide, decane, hydrogen sulfide and fluoromethane.
Abstract: In a preceding project, functional forms for “short” Helmholtz energy equations of state for typical nonpolar and weakly polar fluids and for typical polar fluids were developed using simultaneous optimization. In this work, the coefficients of these short forms for the equations of state have been fitted for the fluids acetone, carbon monoxide, carbonyl sulfide, decane, hydrogen sulfide, 2-methylbutane (isopentane), 2,2-dimethylpropane (neopentane), 2-methylpentane (isohexane), krypton, nitrous oxide, nonane, sulfur dioxide, toluene, xenon, hexafluoroethane (R-116), 1,1-dichloro-1-fluoroethane (R-141b), 1-chloro-1,1-difluoroethane (R-142b), octafluoropropane (R-218), 1,1,1,3,3-pentafluoropropane (R-245fa), and fluoromethane (R-41). The 12 coefficients of the equations of state were fitted to substance specific data sets. The results show that simultaneously optimized functional forms can be applied to other fluids out of the same class of fluids for which they were optimized without significant loss of a...

TL;DR: The role of strongly adsorbed hydrocarbon deposits in reforming catalysis on a series of flat, stepped, and kinked platinum single-crystal surfaces at atmospheric pressures and temperatures between 300 and 700 K has been established and a model developed for the working structure and composition of the active catalyst surface as discussed by the authors.
