“…Rahimpour and Elekaei compared the performance of fluidized-bed membrane dual-type reactor (FMDR) with CR for FTS (Rahimpour, 2008). Moreover, several investigations are performed by Rahimpour et al to apply membranes in dual-type reactors (Rahimpour and Elekaei, 2009a,b;Forghani et al, 2009;Rahimpour et al, 2010).…”

“…Despite such obvious advantages, fluidized-bed membrane reactors have not been widely exploited by industry (Dry, 1990;Unruh et al, 2004). Rahimpour et al improved methanol synthesis reactor and FTS reactor by using a fluidized-bed reactor instead of a fixed-bed reactor (Rahimpour and Elekaei, 2009a,b;Forghani et al, 2009;Rahimpour et al, 2010Rahimpour et al, , 2011.…”

“…In addition, slurry reactors are also operative, for instance installed by Praxair, where a diathermic oil is used to maintain the reactor temperature and catalyst pellets at the desired value while the biosyngas is fed from a bubble sparger places the bottom of the reactor. Membrane (Rahimpour et al, 2010) or cycling-loop (Velardi and Barresi, 2002) reactors represent other interesting alternatives not yet transferred at the industrial scale. The modelling of the Lurgi technology will be considered in this work and a review of the packed bed configurations is currently submitted elsewhere (Bozzano and Manenti, 2015).…”

Development of an Efficient Methanol Production Process for Direct CO2 Hydrogenation over a Cu/ZnO/Al2O3 Catalyst

Carbon capture and utilization as a raw material for methanol production are options for addressing energy problems and global warming. However, the commercial methanol synthesis catalyst offers a poor efficiency in CO 2 feedstock because of a low conversion of CO 2 and its deactivation resulting from high water production during the process. To overcome these barriers, an efficient process consisting of three stage heat exchanger reactors was proposed for CO 2 hydrogenation. The catalyst volume in the conventional methanol reactor (CR) is divided into three sections to load reactors. The product stream of each reactor is conveyed to a flash drum to remove methanol and water from the unreacted gases (H 2 , CO and CO 2 ). Then, the gaseous stream enters the top of the next reactor as the inlet feed. This novel configuration increases CO 2 conversion almost twice compared to one stage reactor. Also to reduce water production, a water permselective membrane was assisted in each reactor to remove water from the reaction side. The proposed process was compared with one stage reactor and CR from coal and natural gas. Methanol is produced 288, 305, 586 and 569 ton/day in CR, one-stage, three-stage and three-stage membrane reactors (MR), respectively. Although methanol production rate in three-stage MR is a bit lower than three stage reactors, the produced water, as the cause of catalyst poisoning, is notably reduced in this configuration. Results show that the proposed process is a strongly feasible way to produce methanol that can competitive with a traditional synthesis process.
