1. Prediction of polyvinyl alcohol (PVOH) properties synthesized at various conditions by artificial neural networks technique

M.R zeynali; M. Nazari; S. Karimi; S. M. Seyedmohaghegh; S. Soltani

Volume 14, Issue 2 , 2017, Pages 3-16

  In this research samples of PVOH were synthesized at various reaction conditions (temperature, time, and amount of catalyst). First at 25˚C and 45˚C and constant catalyst weight samples of PVOH were prepared with different degree of hydrolysis at various times. For investigation of the effects of temperature, ...  Read More

4. Kinetics of Propane Hydrate Formation in Agitated Reactor: A Mass Transfer Approach

P. Goodarzi; V. Mohebbi

Volume 14, Issue 2 , 2017, Pages 48-58

  Understanding the kinetics of gas hydrate formation is essential to model and predict the hydrate formation (or dissociation) process. In the present paper, we investigated the formation of pure propane gas hydrate as a former gas. In this regard, several experiments were conducted to measure the rate ...  Read More

7. A Study of Catalytic Performance of Co3O4 and Cu-Co Nano Metal Oxides in Combustion of Aromatics

S. A. Hosseini

Volume 14, Issue 2 , 2017, Pages 83-90

  Two Cu-Co and Co3O4 oxides were synthesized by the conventional sol-gel auto-combustion and their physical-chemical properties were characterized by XRD, FTIR, SEM, TPR and XPS. The XRD results indicated that copper-cobalt oxide appeared in a mixture form of Cu0.15Co2.85O4 spinel and CuO phases, whereas ...  Read More
