“…In methane combustion, noble metal-based catalysts can also be susceptible to poisoning or thermal stress [260]. Even when supported on monolithic structures, noble metal-based catalysts are expensive and would still be exposed to sintering at the high temperatures employed [261].…”

Considerable research has been conducted on monolithic catalysts for various applications. Strategies toward coating monoliths are of equal interest and importance. In this paper, the preparation of monoliths and monolithic catalysts have been summarized. More specifically, a brief explanation for the manufacturing of ceramic and metallic monoliths has been provided. Also, different methods for coating γ-alumina, as a secondary support, are included. Techniques used to deposit metal-based species, zeolites and carbon onto monoliths are discussed. Furthermore, monoliths extruded with metal oxides, zeolites and carbon are described. The main foci are on the reasoning and understanding behind the preparation of monolithic catalysts. Ideas and concerns are also contributed to encourage better approaches when designing these catalysts. More importantly, the relevance of monolithic structures to reactions, such as the selective oxidation of alkanes, catalytic combustion for power generation and the preferential oxidation of carbon monoxide, has been described.

“…The radiation outputs of the monoliths studied here were calculated based on the surface temperatures measured by the infrared pyrometer and using an effective emissivity  eff of 0.5. Equation (1) is the net calorific value of CH4 at STP (Dupont et al, 2000). The main composition of natural gas is methane.…”

This article discussed the radiation and pollutant emissions characteristics of the catalytic combustion furnace based the combustion of lean natural gas-air mixtures in catalytic honeycomb monoliths and the influence of its exhaust gas on schefflera plants growth by means of theory and experiments. The radiation efficiency of the monolith alone varied from approximately 20% to 40%. The glazed tiles heated by the catalytic combustion furnace are more fine and glossy than that of conventional ones. Schefflera plants in experimental group in a greenhouse filling with catalytic combustion exhaust gas. On contrary, schefflera plants in control group stay in indoor environment. The result showed that schefflera plants in experimental group grow faster than that in control group, even greener. The content of pollutants in the exhaust gas of furnace and the date of the parameter of temperature, humidity and the concentration of CO2 in greenhouse were measured. Catalytic combustion as a developing technology could make the pollutant emissions (CO and NOX) to near zero. The exhaust gas with high CO2 concentration could promote the growth of plants.

“…However, sintering and thermal stability are the main reasons for the decline in the catalytic efficiency in this process. 9,10 Among the investigated catalysts, noble and transition metals are the suitable conventional catalysts. The noble metals (Pd, Pt, Rh, and Ru) have been studied in methane combustion due to the high activity at low temperatures.…”

Lean methane catalytic combustion was studied over various noble metal catalysts supported on 10 wt% BaO-MnO x (BM), and the results demonstrated that the Rh/BM catalyst could present a dramatic change in the light-off temperature. The influence of the Rh loadings on the physicochemical features and catalytic activity and stability in CH 4 combustion was evaluated in detail. The performance of the catalyst was evaluated using the temperatures (T 50% and
