“…For example, the catalytic direct methanation of carbon dioxide can be carried out in a BFB, reaching an average yield and concentration of CH 4 equivalent to 96 % and 88 %, respectively. The results were obtained from experiments conducted in a biogas pilot plant in Zurich (Witte et al, 2019).…”

The growing population and economic development globally has led to increasing resource consumption and waste generation. This has generated concern at local, national and international levels on environmental issues including air quality, resource scarcity, waste management (including plastics) and global warming. The resulting antipathy towards fossil fuels and waste landfilling has spurred the demand for alternative bioenergy and biofuels production methods, making use of abundant biomass and waste feedstock. Although not new concepts, there has been renewed impetus recently to develop advanced thermochemical processes such as pyrolysis and gasification to treat biomass and municipal solid waste (including refuse-derived fuel therefrom). This is because these processes have the potential to add value to cheap and abundant materials by converting them into advanced biofuels and chemicals. The work presented in this paper is concerned principally with the technical analysis and review of new-generation, state-of-the-art systems based on fluidised bed reactors operated with biomass and solid waste. A comprehensive assessment of fluidised bed reactor types and operations is considered, with particular attention given to those processes aimed at the production of clean syngas for the subsequent synthesis of high-value products, including bio-hydrogen, synthetic natural gas (SNG), and liquid fuels.

“…An exemplary synthesis route is elaborated for direct photochemical coupling of 3-CF 3 -aniline with benzene as benchmark. By using capillary photoreactors or fallingfilm microreactors it is guaranteed that thin layers of reaction mixtures are irradiated homogeneously with defined light intensity to avoid side product formation [1]. Heterogeneous catalysts are applied via deposition on reaction plates of the FFMR or by introducing a catalyst suspension into a liquid-liquid slug flow.…”

“…The performance of a fixed bed methanation reactor loaded with a nickel catalyst (Ni/Al 2 O 3 ) has been proven as a reliable technology for pure CO 2 methanation [8,10,17,41,42]. When upgrading CO 2 directly in biogas, the main differences in the reactor design are [9,21,[43][44][45]:…”

In the near future, renewable energy sources will replace fossil energy. To allow full carbon utilization of renewable biomass, we have demonstrated a possible integration between a biogas reactor, an electrolysis unit, and a catalytic methanation reactor. Stringent removal of all sulfur contaminants in raw biogas is required to enable this integration. We demonstrate how existing bulk sulfur removal solutions, like a biotrickling filter loaded with Acidithiobacillus thiooxidans and impregnated activated carbon, are unable to meet this requirement. Only the main sulfur contaminant hydrogen sulfide (H 2 S) can effectively be removed. Contaminants carbon disulfide (CS 2), dimethyl sulfide (DMS), and carbonyl sulfide (COS) will leak through the carbon filter, long before hydrogen sulfide can be detected. Utilization of surplus oxygen from the combined system is proven problem free and allows sulfur removal without introducing contaminants. Provided that a recommended sulfur guard is included, the proposed design is ready for full-scale implementation.
