a one dimensional dynamic model for a riser reactor in a fluidized bed catalytic cracking unit (fccu) for gasoil feed has been developed in two distinct conditions, one for industrial fccu and another for fccu using various frequencies of microwave energy spaced at the height of the riser reactor (fccu-mw). in addition, in order to increase the accuracy of component and bulk diffusion, instanta...

in this thesis, structural, electronical, and optical properties of inverse pervskite(ca3pbo) in cubic phase have been investigated.the calculation have been done based on density functional theory and according to generalized gradiant approximate (gga) as correlating potential. in order to calculate the configurations, implementing in the wien2k code have been used from 2013 version. first of ...

the quest for power has formed much of the world history especially in 20th and 21st centuries. oil (energy) particularly after industrial revolution has been a tool for conquest and power and has been transformed to a geopolitical issue. from a geopolitical point of view this has been the case for the last two centuries in central asia and caucasus. central asia and caucasus has always been...

The present study investigates the effect of globalization on energy consumption in developing countries including Iran for the period 2000 to 2018 in the form of a quantile panel regression approach. For this purpose, the KOF index was used as a globalization variable. The index, KOF, includes real trade flows such as trade, foreign direct investment and portfolio investment, as well as trade ...

This research investigates the main factors that influence green marketing in Iran’s oil industry that can result in sustainable development, based on expertschr('39') opinions. The methodology of this research is grounded in theory and adopts a qualitative research approach.  We use semi structural deep interviews to collect our data.  We analyze the data using three stages of coding: open, ax...

Energy is considered as one of the most urgent and critical requirements of development.The high demand for energy from fossil fuels makes economic growth easy, but the current energy system is not sustainable due to its negative effects on the environment and human life. Sustainable development has been defined as a development that will provide the needs of the present generation without comp...
