• Kinetic modeling for steam reforming of naphtha surrogates on NiMgAl catalyst. The model discrimination was conducted based artificial neural networks. Ab initio (DFT) calculations allow further refinements and corroborations. selected kinetic satisfactorily captures catalyst activity selectivity. validated a wider set operating conditions feedstocks. Steam hydrocarbons is will be, in the sho...

A mathematical model for commercial naphtha catalytic reformer of Tehran refinery was developed. This model includes three sequencing fixed beds of Pt/Al2O3 catalyst at the steady state condition using detailed kinetic scheme involving 26 pseudo-components connected by a network of 47 reactions, in the range of C6 to C9 hydrocarbons. The reaction network consisted dehydrogenation, hydrogenation...

Complex process networks featuring multiple energy integration agents (processto-process heat exchangers) offer significant cost benefits while adding additional operational constraints. These networks show potential for multi-time scale dynamics owing to the presence of energy flows spanning multiple orders of magnitude. In previous work, we have developed a graph-theoretic framework to system...

As part of a study on health effects of naphtha exposure, the association between naphtha exposure and urinary excretion of total protein, albumin, beta-N-acetyl-D-glucosaminidase (beta-NAG), and beta 2-microglobulin was assessed prospectively over 1 year among workers at an automotive plant that used naphtha to calibrate fuel injectors. Participants consisted of 248 workers who provided spot u...
