1. Improved numerical simulation of the low temperature Fischer-Tropsch synthesis in a trickle bed reactor

H. Salimi; Sh. shahhosseini

Volume 15, Issue 1 , Winter 2018, Pages 1-17

  Abstract Gas to liquid (GTL) process involves heterogeneous catalytic chemical reactions that convert synthesis gas to hydrocarbons and water vapor. A three phase reactor, called Low temperature Fischer-Tropsch (LTFT) is commonly applied for GTL process. In this reactor the gaseous phase includes the ...  Read More

2. Assessment of effective factors on bacterial oxidation of ferrous iron by focusing on sweetening natural gas

A. Zabihollahpoor; P. Hejazi

Volume 15, Issue 1 , Winter 2018, Pages 18-34

  In this study, the effects of some factors on bacterial growth and ferrous oxidation rates were investigated by Acidithiobacillus ferrooxidan in 250 ml shake flasks. One factor at a time (OFAT) design approach was used for preliminary evaluation of various factors affecting the process, such as pH, initial ...  Read More
