a study on thermodynamic models for simulation of 1,3 butadiene purification columns
attempts have been made to study the thermodynamic behavior of 1,3 butadiene purification columns with the aim of retrofitting those columns to more energy efficient separation schemes. 1,3 butadiene is purified in two columns in series through being separated from methyl acetylene and 1,2 butadiene in the first and second column respectively. comparisons have been made among different therm...
Mobility measurements of two kinds of two-dimensional fluids. Methane adsorbed on graphite
2014 The diffusion coefficient of a CH4 submonolayer adsorbed on (0001) graphite is measured as a function of coverage and temperature by quasi-elastic neutron scattering. The experimental data permit us to clearly distinguish two kinds of adsorbed fluids, i.e. a 2D liquid coexisting with a 2D gas and a 2D hypercritical fluid whose density varies continuously with coverage. The mobility disappe...
متن کاملThermodynamic study of the 4 He monolayer adsorbed on Grafoil *
A calorimetric and vapor-pressure study of the behavior of 'He adsorbed on Grafoil III the temperature range 4 to 15 K is reported. These results have been combined with preexisting low-temperature heat-capacity data to form a complete thermodynamic description of the film, The Grafoil substrate evidently consists almost entlrely of basal-plane graphite, with only a small fraction of energetica...
متن کاملA first order two-dimensional melting transition : methane adsorbed on (0001) graphite
2014 The variation of long range order of a registered solid submonolayer of methane adsorbed on the graphite basal plane is measured at melting by neutron elastic scattering. The sudden loss of order indicates a first order melting transition and defines the two-dimensional triple point of the layer, namely 56 ± 0.4 K.

متن کاملMono- and multilayers of molecular spoked carbazole wheels on graphite
Self-assembled monolayers of a molecular spoked wheel (a shape-persistent macrocycle with an intraannular spoke/hub system) and its synthetic precursor are investigated by scanning tunneling microscopy (STM) at the liquid/solid interface of 1-octanoic acid and highly oriented pyrolytic graphite. The submolecularly resolved STM images reveal that the molecules indeed behave as more or less rigid...
