Introduction Separation and purification of the chemical species from a mixture is a crucial part of nowadays chemical process industry. The latest improvements in membrane separation processes caused the growth of some industries, even some processes. Over the last years, membrane separation processes are utilized from the simple process units to the complex process units like reactors. Basically, when reactors operate with a membrane separation process, it is called as a membrane reactor. Several enhancements made in membrane technology, since the concept of membrane reactor was introduced, lead to the case that many companies find it convenient to use membrane reactors in order to accomplish the task. The major reason why we take advantage of membrane reactors is a desired higher conversion through the process. However, there could be the questions like could the changes in temperature make an improvement in conversion? This is not actually the case for some reactions that are restricted by thermodynamic…show more content…
Biomembranes wield integral and peripheral proteins that is basis for the transportation of chemicals and ions. Biological membranes are easy to manufacture while they present many drawbacks such as limited operating temperature, pH range, some clean-up issues and susceptibility to microbial attack. On the other hand, synthetic membranes can be subdivided into organic and inorganic membranes. Inorganic membranes are stable to work with higher temperature (300 - 800⁰ C, even 1000⁰ C for ceramic membranes) and chemical degradation, yet they are too expensive. They are constituted from various materials such as ceramic, carbon, silica, zeolites, oxides and metals (mainly palladium and its alloys) where organic membranes are made of commercial polymers with the drawback of lower resistance to higher
