Hydrogen and syngas production by hybrid filtration combustion: Progress and challenges

Thermal decomposition of sulfur brown coal

“…The weight of the samples was 25.0 g. The coal particles used had an average size of 1.5, 2.5 and 5.0 mm. During rapid heating, a sample of coal was placed in a furnace heated to a given temperature, ranging from 500 to 1200°C (every 100°C), and kept in the furnace for 15 s, which corresponds to the residence time of the particle in the high-temperature zone during gasification in filtration mode [24][25][26]. During gradual heating, the samples were simultaneously placed inside the furnace on eight quartz cuvettes, after which the furnace was turned on.…”

Thermogravimetric analysis of gasification and pyrolysis of algae biomass

“…Thermochemical conversion processes play a crucial role in the efficient and long-term utilization of biomass. These processes, such as direct combustion, gasification, pyrolysis, torrefaction and liquefaction offer versatility by enabling the production of diverse forms of bioenergy and bioproducts from various types of raw biomass and waste residues [16][17][18][19].…”

“…Established technical processes exist for synthesizing Fischer-Tropsch diesel, dimethyl ether, methanol, and methane from this syngas. The process of biomass gasification involves partially oxidizing the carbon of biomass at high temperatures with a controlled amount of oxidant, which can be air, pure oxygen, or steam [23]. The properties and composition of the resulting syngas are influenced by factors such as the type of biomass used, the gasifier design, and the operational conditions, including the choice of oxidant and temperature in the gasifier.…”

European Green Deal: An Experimental Study of the Biomass Filtration Combustion in a Downdraft Gasifier

“…According to the European Green Deal, it is necessary to reduce greenhouse gas emissions by 55% (from 1990 to 2023) and ensure sustainable economic growth without increasing the use of fossil fuel resources [3]. Reducing greenhouse gas emissions requires an increase in the Energies 2023, 16, 7490 2 of 15 share of renewable sources in energy production [4] and the development of new types of relevant equipment [5].…”

“…Nevertheless, the existing availability of relatively cheap fossil fuels motivates scientists to look for ways of reducing the cost of combustible gas production and the energy created from it [15]. One of the ways is filtration burning in a superadiabatic mode, which makes it possible to gasify wet biomass more effectively, producing energetic gas and liquid hydrocarbons [16].…”
