“…In 2011, a new configuration has been proposed by Rahimpour et al [56]. In this configuration a fixed-bed water perm-selective membrane reactor is followed by a fluidized-bed hydrogen perm-selective membrane reactor [(fixed-bed membrane and fluidized-bed membrane dual reactor (FMFMDR)] which is shown in Figure 13.…”

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.

The Formox process is a well‐known process for formalin generation, which uses iron‐molybdenum oxide as a catalyst. Typically, the off‐gas from the formaldehyde absorption column in Formox process is burnt in the emission control system (ECS), resulting to produce a huge amount of CO2. This work proposes a modified process to remove formaldehyde and volatile organic compounds from the stack of formaldehyde absorbing tower. Steam reforming reactions in a novel fixed‐bed tubular membrane reactor is used instead of combustion reactions in a conventional fixed‐bed reactor in ECS. The process was modeled to evaluate the role of membrane reactor for CO2 mitigation in Formox process. The collected data from a domestic formalin plant were used for modeling purposes. The model was validated against experimental measurements obtained from other works. A good consistency was observed. The improvement in CO2 emission mitigation, as well as H2 production, was achieved by applying the Pd‐Ag membrane reactor filled with copper‐based catalyst. The CO2 emission rate considerably changed from 6,700 to 575 kg/day. Furthermore, by using the proposed reactor, the emission of formaldehyde and methanol vapors throughout the ECS plant were eliminated. The essential parameters such as reactor pressure, temperature, and membrane thickness on reactor performance were evaluated. By increasing the feed temperature, the carbon dioxide production rate decreases, and pure hydrogen production rate increases. The higher CO2 generation was observed at elevated pressures. The effect of membrane thickness on CO2 emission was negligible.
