Abstract
This paper reports the findings of a FP7 project (DEMCAMER) that developed materials (catalysts and membranes) and new processes for four industrially relevant reaction processes. In this project, active, stable, and selective catalysts were developed for the reaction systems of interest and their production scaled up to kg scale (TRL5 (TRL: Technology Readiness Level)). Simultaneously, new membranes for gas separation were developed; in particular, dense supported thin palladium-based membranes for hydrogen separation from reactive mixtures. These membranes were successfully scaled up to TRL4 and used in various lab-scale reactors for water gas shift (WGS), using both packed bed and fluidized bed reactors, and Fischer-Tropsch (FTS) using packed bed reactors and in prototype reactors for WGS and FTS. Mixed ionic-electronic conducting membranes in capillary form were also developed for high temperature oxygen separation from air. These membranes can be used for both Autothermal Reforming (ATR) and Oxidative Coupling of Methane (OCM) reaction systems to increase the efficiency and the yield of the processes. The production of these membranes was scaled up to TRL3–4. The project also developed adequate sealing techniques to be able to integrate the different membranes in lab-scale and prototype reactors.
Highlights
Global warming and fossil fuels scarcity necessitate the transformation of traditional processes towards more sustainable and efficient processes for both energy conversion and chemical transformations

The whole process was designed starting from the development of the catalyst for the process, The whole process was designed starting from theconditions development of the catalyst for the process, which should show good activity under the operating in membrane reactors
Summary
Global warming and fossil fuels scarcity necessitate the transformation of traditional processes towards more sustainable and efficient processes for both energy conversion and chemical transformations. With high efficiency as well asaaccomplishing reduction in CO2 emissions to the atmosphere, Within the chemical engineering framework, the development of more active catalysts, more achieving a large positive impact as compared to benchmark technologies [2]. The technology of membrane reactors has been recently developed and has demonstrated membrane based separation and a where catalytic chemical reaction take place in one unit [3,4,5,6,7,8,9]. High degree of process intensification the combination of a membrane based separation and Membranes can be used in membrane reactors for either selective gas separation from the reaction a catalytic chemical reaction take place in one unit [3,4,5,6,7,8,9].
