[ 1 ] - A Novel Study of Upgrading Catalytic Reforming Unit by Improving Catalyst Regeneration Process to Enhance Aromatic Compounds, Hydrogen Production, and Hydrogen Purity
Catalytic reforming is a chemical process utilized in petroleum refineries to convert naphtha, typically having low octane ratings, into high octane liquid products, called reformates, which are components of high octane gasoline. In this study, a mathematical model was developed for simulation of semi-regenerative catalytic reforming unit and the result of the proposed model was compared with ...
[ 2 ] - Optimization of Semiregenerative Catalytic Naphtha Reforming Unit to Enhance Octane Number and Reformate Yield
Catalytic naphtha reforming is one of the most important processes in which, low quality naphtha is converted into high octane motor gasoline. In this study, a mathematical model was developed and was used for investigation the effect of temperature, pressure, hydrogen to hydrocarbon ratio on the octane number, the yield of product and the undesirable phenomena of coke deposition in a semiregen...
[ 3 ] - A Fugacity Approach for Prediction of Phase Equilibria of Methane Clathrate Hydrate in Structure H
In this communication, a thermodynamic model is presented to predict the dissociation conditions of structure H (sH) clathrate hydrates with methane as help gas. This approach is an extension of the Klauda and Sandler fugacity model (2000) for prediction of phase boundaries of sI and sII clathrate hydrates. The phase behavior of the water and hydrocarbon system is modeled using the Peng-Robinso...
[ 4 ] - Liquid Density Modeling of Pure Refrigerants Using Four Lattice-Hole Theory Based Equations of State
The present study investigates the performance and relative accuracy of four lattice-hole theory based equations of state in modeling and correlating the liquid density of pure refrigerants. Following the gathering of a database of 5740 experimental liquid density datapoints of 36 pure refrigerants belonging to five different categories including CFCs, HCFCs, PFCs, HFCs and HFEs, ranging from 6...
