in thermal cracking plants, it is desired to apply an optimal temperature profile along the reactor to minimize the operation cost. in this article a simulator is developed by the use of a mathematical model, which describes the static operation of a naphtha thermal cracking pilot plant. the model is used to predict the steady state profiles of the gas temperature and product yields. using a dy...

This work studied the facilitation of transportation Missan heavy crude oil characterized with high viscosity 84.61 cp at 15 °C, low API 23.1,  by reducing its from break down asphaltene agglomerates using five solvents some novel combinations chemical additives were used for this study (naphtha & toluene, naphtha xylene, kerosene, toluene and xylene kerosene).The was measured after be...

Fuel quality is an important indicator for the suitability of alternative fuel utilization in internal combustion (IC) engines. In this paper, light naphtha and fusel oil have been introduced as additives local low octane gasoline to operate a spark ignition (SI) engine. Investigated samples prepared based on volume denoted GN10 (90% 10% naphtha), GF10 oil), GN5F5 gasoline, 5% oil) addition G10...

10-membered ring IM-5 zeolite has shown excellent performance in many catalytic reactions. The efficient preparation of high silica by situ synthesis remains huge challenge. Here, with SiO2/Al2O3 ratio (SAR) 49–116 was acquired HNO3 treatment. An interesting stepwise dealumination behavior discovered during the whole acid-treatment process (based on XRF characterization). Extra-framework Si (EF...
