Abstract
  1,3-Butadiene, BD is produced from C4-cut by extractive distillation. The separation of 1,3-Butadiene from C4-cut is not possible through the conventional distillation processes, because several mixtures have consisted of close boiling points constituents and make azeotrope. The BASF extraction distillation ...  Read More

Hiva Roboubi; Yadollah Mortazavi; Abbas Ali Khodadadi

Volume 42, Issue 8 , February 2009, Pages 983-988

https://doi.org/10.22059/jac.2013.7818

Abstract
  For the first time, this research reports the formation of nanoporous layers of metals on the surface of metal substrates by Raney method and their conversion to corresponding porous perovskite layers. The noble metals doped perovskites are used as catalytic converter for reducing automotive pollutants. ...  Read More

ساخت و بررسی عمل کرد سنسور اکسیژن و بهبود آن با استفاده از نیمه هادی اکسید فلزات تیتانیوم و سزیم و قلع به عنوان مرجع‌های جامد

Afsaneh Sheykh Mohammadi; Yadollah Mortazavi; Abbas Ali Khodadadi; Yousef Zeynali

Volume 42, Issue 8 , February 2009, Pages 989-998

https://doi.org/10.22059/jac.2013.7819

Abstract
  We report the development of different types of oxygen sensors based on yittria-stabilized zirconia (YSZ) as a solid electrolyte. The conventional oxygen sensor is a concentration cell with two porous Pt electrodes, one of which is exposed to air as a constant (reference) oxygen concentration and the ...  Read More

تحلیل آماری و مدل سازی فاز اسپورزایی در فرآیند تخمیر باکتری باسیلوس تورنژنسیس جهت تحلیل تأثیر اکسیژن و زمان کشت بر فعالیت حشره زدایی آن

Volume 42, Issue 8 , February 2009, Pages 1025-1034

https://doi.org/10.22059/jac.2013.7821

Abstract
  Due to the importance of Bacillus thuringiensis (Bt) in the biological fight, it is necessary to optimize its fermentation process and decrease its production cost. Statistical analysis is used not only to optimize fermentation conditions but also to describe and predict the culture behavior. In production ...  Read More

مدل سازی ریاضی انتقال جرم گازها در غشا‌ءهای نامتقارن متخلخل پلیمری

Sara Farhangi; Mojtaba Shariati Niasar; Mohammad Soltanieh; Mehdi Pourafshari Chenar

Volume 42, Issue 8 , February 2009, Pages 1007-1016

https://doi.org/10.22059/jac.2013.7822

Abstract
  It is several decades that the application of membrane processes for gas separation has become a great concern within industries. Among them, the polymeric membranes of different structures have played the most important role. Such application has been widely extended to gas separation and due to the ...  Read More
