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...

homogenous charge compression ignition (hcci) combustion is spontaneous multi-site combustion of a nominally premixed air/fuel mixture that exhibits high rate of pressure rise and short combustion duration. to avoid excessive pressure rise rate and knocking, hcci engines are fueled with highly diluted mixture using a combination of excess air and/or egr. hcci combustion is attractive due to ext...

For many years radiation thermometers have been used to make non-contact temperature measurements of hot objects, particularly in industrial situations such as reformer furnaces, steel reheat furnaces, and ceramics kilns. They occupy an important niche in temperature measurement since any other type of thermometer would have very slim chances of surviving in these and other such hostile environ...

This study aimed to investigate the effects of 8-week mat and reformer pilates exercises on functional movement skills, flexibility adult healthy sedentary women. 58 [reformer exercise group (n: 20), 21) control 17)] volunteer women participated in study. Functional Movement Screen test (FMS), sit reach test, Trunk lateral flexion Quadriceps Femoris M.Iliopsoas were applied participants. Two-wa...

Key decisions in developing a model of steam methane reformer were investigated this paper. A comprehensive one-dimensional Python tube is proposed, including the effects o...
