Summary: Dry reforming of methane (DRM) is a promising process for producing synthetic gas, and the design of an effective catalyst is crucial. In this study, nickel catalysts supported by calcium hydroxyapatite (HAP) and HAP-doped magnesium (Mg_HAP) were synthesized and evaluated in the DRM reaction. The Ni/HAP and Ni/Mg_HAP catalysts showed outstanding performance due to the tunable acidity-basicity of the supports, strong metal-support interaction, and good thermal stability of nickel nanoparticles. The main products were H2 and CO, with stable selectivity around 85%, while H2O and solid carbon were byproducts with 5-10% selectivity.

Summary: This study investigates the use of non-thermal plasma in a swirl-induced electrode discharge reactor for the dry reforming of methane. The reactor design promotes better mixing of reactant gases, leading to increased conversion rates. The study examines the effect of flow rates and compositions of CO2/CH4 on conversion, and analyzes the characteristics of the produced syngas and solid carbon. The findings show that higher concentrations of CO2 or CH4 result in increased conversion, while increasing flow rates reduce energy costs.

Summary: The parallel electrodes gliding plasma (PEGP) is a novel approach for the dry reformation of methane, providing high conversion rates and energy efficiencies. Compared to traditional glide plasma, PEGP demonstrates superior performance in molecular dissociation. By dissipating the energy in the layers of fresh reactants gas instead of overheating or dissociating the products, higher performance is achieved.

Summary: Perovskite-derived catalysts in dry reforming of methane exhibit superior catalytic performance due to the synergistic effects of bimetallic addition at the B site and enhanced oxygen mobility through A site substitutions. The use of high surface area supports also greatly influences the physicochemical and catalytic behavior of perovskite-derived catalysts. The exsolution process involved in the reduction of perovskite catalysts produces smaller size metal particles which dictate the superior catalytic performance of these materials.

Summary: In recent years, there has been increased interest in dry reforming of methane to obtain syngas using CO2. Achieving high conversion rates requires working at temperatures above 1000 degrees C, but to prevent catalyst deactivation, it is convenient to work at lower temperatures. A simulated process in this work successfully recovered syngas from a dry reforming reaction at 700 degrees C, with purity and recovery rates exceeding 99%. The process also allows for the recycling of unreacted CO2 and CH4, leading to effective conversion rates close to 100%.

Summary: Dry reforming of methane (DRM) is a green alternative for utilizing greenhouse gases and producing syngas. The main limitations of DRM are catalyst sintering and coking. Recent studies have focused on Ni-based catalysts for DRM due to economic constraints on noble metal-based catalysts. Mesoporous silica (MS) supported catalysts show promise due to their high surface areas, thermal stability, and easy availability. However, research on MS as a catalyst support for DRM is still limited.
