“…Zeolite Y has catalytic activity without active phases due to the surface acidity to decompose methane and high affinity for CO 2 adsorption [47,54,55]. In the past researches, the performance of Ni, Pt and Rh over zeolites were evaluated in DRM process [47,48]. From an industrial point of view, Rh and Pt are not the suitable active phases for this process due to their low availability and high cost [40,47].…”

“…Additionally, other properties of zeolite Y such as potential to deliver very high metal dispersion and superior coke resistance introduce it as an important catalyst support in CO 2 reforming of CH 4 [48,53]. Zeolite Y has catalytic activity without active phases due to the surface acidity to decompose methane and high affinity for CO 2 adsorption [47,54,55]. In the past researches, the performance of Ni, Pt and Rh over zeolites were evaluated in DRM process [47,48].…”

“…In order to resolve catalysts drawbacks in DRM process, many supports were evaluated in dry reforming of methane at the past studies. They can be listed as SiO 2 [17], MgO [43], ZrO 2 [3], Perovskite [44], TiO 2 [45], CeO 2 [34], La 2 O 3 [46], clinoptilolite [20], ZSM-5 [2], zeolite (X, Y, A) [47,48], mixed-oxide derived from hydrotalcite [49,50] and c-Al 2 O 3 [11,36,51,52]. The results of studies revealed that zeolite Y greatly improves both selectivity and stability of DRM reaction due to the especial properties such as: high surface area, surface acidity, microporous structure of zeolite Y and high affinity for CO 2 adsorption [48,53].…”

The catalytic activity of Ni-Rh on the synthesized BEA zeolite in carbon dioxide reforming of methane has been investigated. Catalysts were prepared using the incipient wetness impregnation method, with a total content of metals up to 5 wt%. Catalysts were characterized through XRD, TPR, N 2 adsorption, SEM, AAS, TG/DSC analyses. The prepared Ni-Rh zeolites were tested for their catalytic activity at 700°C, at atmospheric pressure, and at CH 4 /CO 2 ratio of 1. Catalytic results showed that bimetallic based zeolites exhibit high activity (CH 4 and CO 2 conversion equal to 73 and 78, respectively) but monometallic Rh catalysts were the only one stable against coke formation.

Abstract. GTL (Gas-to-liquid) process is becoming an attractive technology which can produce liquid petroleum products using natural gas. As a part of preliminary design of GTL-FPSO application, process simulation analysis for conceptual design and optimization of reformers and F-T reactors are performed in GTL-FPSO applications by implementing the user made subroutine programs of kinetic equations into PRO/II PROVISION simulator. As for the F-T reactors, Plug Flow Reactor (PFR) model is used with detailed kinetics equations over two different Fe based catalysts (Fe-Cu-K and K/Fe-Cu-Al). Dry reformer is also studied with Plug Flow Reactor (PFR) model. In this study, simulation results are compared with available experimental data and found well agreed with experimental data for both reformer and FT reactor. The Peng-Robinson equation of state is also used to calculate the vapor phase nonidealities and vapor-liquid equilibrium. The optimum operating conditions and process simulation analysis are also presented.
