Mathematical modeling of a fixed bed chromatographic reactor for Fischer Tropsch synthesis
Volume 3, Issue 3 , July 2006, , Pages 51-64

Abstract
  In this research, Fischer Tropsch synthesis (FTS) has been modeled in the fixed bed chromatographic reactor for the first time by applying a rather complex dispersed plug flow model for fluid phase and linear driving force (LDF) model for adsorbent. Model equations are dynamic, multi-component, non-linear ...  Read More

Some investigations on PHA production using activated sludge as inoculum
Volume 2, Issue 2 , April 2005, , Pages 56-63

Abstract
  This paper indicates that activated sludge under certain conditions can achieve levels of polyhydroxyalkanoates (PHA) accumulation which would enable the economic recovery of this precursor of biodegradable plastics. The effects of C/N ratio and temperature on polyhydroxyalkanoates production were evaluated. ...  Read More

Characterization of Copper-Manganese Oxide Catalysts and Their Precursors: Effect of Precipitate Aging upon the Structure and Morphology of Precursors and Catalysts
Volume 1, Issue 2 , July 2004, , Pages 11-18

Abstract
  Copper-manganese oxide catalysts are prepared with an atomic ratio of Cu/Mn=2/1 using a coprecipitation procedure under air atmosphere. The time of aging, i.e., the time that precipitate remains in contact with the precipitating medium, has been varied from 0 (for unaged precursor) to 300 minutes and ...  Read More
