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...

Reduction of harmful emissions in the combustion of fossil fuels imposes tighter specifications limiting the sulfur content of fuels. Hydrodesulfurization (HDS) is a key process inmost petroleumrefineries inwhich the sulfur ismostly eliminated. Themodeling and simulation of the HDS process are necessary for a better understanding of the process operation; it is also a requirement to optimize pr...
