Determination of rate parameters of complex reactions by polymath
Özdemir, Burcu; Gültekin, Selahattin (Bentham Science Publishers, 2009)Generally, consecutive and/or parallel reactions pose a great deal of difficulty in determining meaningful reaction rate parameters. One way to determine such parameters is to separate the whole reaction network into ... -
The effects of cutting and drying medium on the vitamin C content of rosehip during drying
Erentürk, Saliha; Gülaboğlu, Mustafa Şahin; Gültekin, Selahattin (Elsevier, 2005-06)Kinetics of ascorbic acid degradation during air-drying of whole rosehip has been investigated. Changes of vitamin C content during drying have been affected by drying time, drying air temperature and as well as moisture ... -
An experimental study on the kinetics of leaching for the preparation of a Raney-Silver catalyst
Salt, İnci; Gültekin, Selahattin (Kluwer Academic Publishers, 2004)A Raney-Ag catalyst was prepared by leaching out aluminium from a Raney Ag-Al alloy with NaOH solution. The kinetics of leaching has been investigated in a stirred-batch-reactor at various temperatures by using alloy ... -
Influence of some processing parameters on drying kinetics of rose hips
Erentürk, Saliha; Gülaboğlu, Mustafa Şahin; Gültekin, Selahattin (International Society for Horticultural Science, 2005)The influence of temperature, velocity and humidity on thin layer drying of rose hips was investigated. A laboratory air drier was designed and used for the drying experiments. The system was operated at an air temperature ... -
Model discrimination in chemical kinetics
Özdemir, Burcu; Gültekin, Selahattin (Bentham Science Publishers, 2009)In studies on chemical kinetics, generally after the rate data have been taken, a mechanism and an associated rate law model are proposed based on the data taken. Frequently, more than one mechanism and rate law may be ... -
The thin-layer drying characteristics of rosehip
Erentürk, Saliha; Gülaboğlu, Mustafa Şahin; Gültekin, Selahattin (Elsevier, 2004-10)In this study, the influence of air temperature, velocity and humidity on the thin-layer drying of rosehip was investigated. A laboratory air drier was designed and used for drying experiments. The system was operated in ... -
Vitamin C degradation of rose hips during drying and effects of drying medium on vitamin C degradation
Erentürk, Saliha; Gülaboğlu, Mustafa Şahin; Gültekin, Selahattin (International Society for Horticultural Science, 2005)In this study, vitamin C degradation during drying of rose hips was investigated. The degradation of vitamin C was affected by time, temperature and content of moisture. Rate of vitamin C degradation during the drying of ...
