A Ni/CeO2/ZrO2 catalyst with improved redox properties has been washcoated onto a honeycomb cordierite monolith in the form of a nonconventional alumina-catalyst layer, just a few nanometers thick. In spite of the very low active phase loading, the monolith depicts outstanding performance in dry reforming of methane, both in terms of activity, with values reaching the thermodynamic limit already at 750 °C, even under extreme Weight Hourly Space Velocities (WHSV 115–346 L·g−1·h−1), as well as in terms of stability during prolonged Time on Stream (TOS 24–48 h).

High Temperature Reaction

Positive environmental and technological contexts make dry methane reforming (DMR) an extensively studied reaction. During this process two main greenhouse gases CH4and CO2can be simultaneously converted into syngas – a mixture of CO and H2. Supported-nickel is one of the most frequently applied DMR catalysts. Their activity depends mainly on Ni concentration, kind of its precursor and a deposition method. As DMR is a demanding high-temperature reaction, it requires not only an active but first a very stable catalyst. Structural, textural and functional properties of such support remain thus of crucial efficiency. Main aim of this work was to elucidate how the synthesis of CeO2-ZrO2support obtained by supercritical fluid method (i.e.at temperature of 400°C under a pressure of 25 MPa), can influence the properties of Ni-based DMR catalysts. The supports of various compositions (CeO2content from 100 to 0 %), subsequently calcined at 800°C for 6h in air have been analyzed. Nickel was deposited from nitrate(V) precursor via classical wet impregnation. The final catalysts have been characterized structurally (XRD, RS), texturally (BET, SEM) and functionally (UV/Vis-DR, XPS). Catalytic tests in dry methane reforming reaction have been performed to determine activity and stability of the synthesized samples.

Critical Overview

Membrane reactors technology represents a promising tool for the CO2 capture and reuse by conversion to valuable products. After a preliminary presentation of the fundamentals of this technology, a critical overview of the last achievements and new perspectives in the CO2 conversion by membrane reactors is given, highlighting the still existing limitations for large scale applications. Among the low temperature (≤100 °C) membrane reactor for CO2 conversion, electrochemical membrane reactors and photocatalytic reactors, represent the two mainly pursued systems and they were discussed starting from selected case studies. Dry reforming of methane and CO2 hydrogenation to methanol were selected as interesting examples of high temperature (>100 °C) membrane based conversion of CO2 to energy bearing products.
