The present review focuses on the current progress on harnessing the potential of hydrogen production by Methane Steam Reforming (MSR). First, based on the prominent literature in last few years, the overall research efforts of hydrogen production using different feed stocks like ethanol, ammonia, glycerol, methanol and methane is presented. The presented data is based on reactor type, reactor operating conditions, catalyst used and yield of hydrogen to provide a general overview. Then, the most widely used process [steam methane reforming (SMR)/methane steam reforming (MSR)] are discussed. Major advanced reactors, the membrane reactors, Sorption Enhanced methane steam reforming reactors and micro-reactors are evaluated. The evaluation has been done based on parameters like residence time, surface area, scale-up, coke formation, conversion, space velocity and yield of hydrogen. The kinetic models available in recently published literature for each of these reactors have been presented with the rate constants and other parameters. The mechanism of coke formation and the rate expressions for the same have also been presented. While membrane reactors and sorption enhanced reactors have lot of advantages in terms of process intensification scale-up to industrial scale is still a challenge due to factors like membrane stability and fouling (in membrane reactors), decrease in yield with increasing WHSV (in case of Sorption Enhanced Reactors). Micro-reactors pose a higher potential in terms of higher yield and very low residence time in seconds though the volumes might be substantially lower than present industrial scale conventional reactors.

“…Several models exist in the literature to describe the SMR reaction. It can be divided to three types: Langmuir–Hinshelwood based models 42‐45 ; first order in methane‐based models 46‐49 ; power law–based models 23,30,50,51 . The simplest mathematical approach used in the literature are based in the power law model, which depends on the first order in methane and water vapor.…”

In this research, an evaluation of the performance improvement of a new reactor configuration for steam methane reforming (SMR) is carried out through a numerical-experimental approach. Two configurations of M-PCR have been studied numerically to compare the benefits. The first one consists of a conventional micro planar cell reactor (noted clear M-PCR), which is impregnated in its central axis in the direction of gas mixture flow by Ni/Al 2 O 3 catalyst. The second M-PCR configuration is equipped with nickel-based metal foam (MF) (noted M-PCR MF), which supports similar catalyst layer as for clear M-PCR configuration. The same operating conditions and catalyst weight density are set. 2D numerical solution of the transport equations was performed with a homemade code based on FORTRAN language to explore the heat and mass transfer during the SMR process. To better evaluate the nickel-based MF effects, permeability coefficients, that is, Darcy and inertial coefficients, were first measured using an experimental bench for hydrodynamic characterization of porous media. Comparison has showed that M-PCR MF configuration provides a significant enhancement in terms of hydrogen yield (73,25%). Furthermore, the catalyst layer length could be reduced by four times compared to conventional M-PCR due to MF implementation, leading to important economic improvement while keeping an interesting SMR efficiency.

“…Other kinetic models with associated rate expressions for SMR on various catalyst systems have been proposed using different kinetic modelling approaches. Power law approach was used to develop kinetic models for SMR on Rh-Ni/MgAl 2 O 4 catalyst and Ni-YSZ (yttriastabilized zirconia) cermet by Katheria et al [71] and Sugihara et al [72], respectively. Other kinetic models employing Langmuir-Hinshelwood approach have been developed for Ni/a-Al 2 O [73], Nickel/Calcium Aluminate [70] and LaNiO 3 perovskite-type oxide [74] catalyst systems.…”
