“…The presence of the membrane controls hydrogen addition in a way that H 2 /CO ratio would be set to its optimum value. Rahimpour et al [4] suggested the counter-current mode for the dual type hydrogen perm-selective membrane reactor. The mentioned dual type reactor was optimized by Rahimpour and Elekaei [5] which resulted in higher CO and H 2 conversion and gasoline production.…”

“…In 2010, Rahimpour et al [74] made a comparison of co-current and counter-current modes of operation for a novel hydrogen perm-selective membrane reactor. In both modes of operations, a system with two catalyst bed instead of one single catalyst bed is developed for FTS reactions.…”

“…In the co-current mode, feed gas enters the tubes of the second reactor in the same direction with the reacting gas flow in shell side, while in the counter-current mode the gas streams are in the opposite direction. The counter-current mode of operation decreases undesired products such as CO 2 and CH 4 and also produces more gasoline [74]. A summary of the different dual-type membrane reactors are shown in the first part of Table 4.…”

High-temperature Fischer-Tropsch (HTFT) process aims to produce lighter cuts such as gasoline and diesel. For many years there have been studies and improvements on HTFT process to make the existing reactors more efficient. Recent studies proposed new configurations such as dual-type membrane reactor and coupling configurations reactor, which improved the performances of this process. This achievement persuades us to update the existing knowledge about the available reactors for HTFT process. In this article, features and performances overview of two classes of reactors are reviewed. The first class consists of the reactors which are based on older studies, and the second one includes recent studies which are called product intensifier reactors. Finally, it is shown that the product intensifier reactors have higher CO conversions and lower selectivity of undesired by-products which results in higher production yield of gasoline. Furthermore, the place of product intensifier reactor among common reactors with regard to the influence of the process parameters on the product distribution has been estimated.

Natural gas emissions contribute to climate change, and equally importantly, affect the health of populations near gas fields.[1] At night, the flares from the Bakken fields in North Dakota burn as bright as the lights in cities as large as Minneapolis. Rather than flaring (or worse, venting), this associated natural gas represents a multi‐billion dollar opportunity.[2] Pipelines and liquefying natural gas are cost prohibitive in many cases. Converting methane to fuels is an attractive alternative. We examined three options to convert natural gas to syngas (H2 and CO), which is the first step to producing fuels: Steam Methane Reforming (SMR), Auto‐Thermal Reforming (ATR), and Catalytic Partial Oxidation (CPOX). Based on a multi‐objective optimization analysis, C5+ hydrocarbon yields are highest with CPOX as the first step followed by Fischer‐Tropsch synthesis (FT). A micro‐refinery with the CPOX‐FT process treating 2800 normalkL·d−1 (100 MCF·d−1) natural gas, produces 1300 normalL·d−1 (8.2 bbl·d−1) of C5+ hydrocarbons. Maximum yields for the SMR‐FT and ATR‐FT processes are 938 normalL·d−1 and 1100 normalL·d−1 (5.9 bbl·d−1, 7.0 bbl·d−1) of C5+, respectively. Large‐scale POX and ATR processes produce 1600 L per 2800 kL (10 bbl per 100 MCF) of natural gas.
