Abstract: A device for preparing a high-temperature and active particle-containing steam. The device includes a steam generator including an inlet for introducing a plasma medium and an inlet for introducing a steam. In the steam generator, the steam is heated and activated by the plasma medium to form an active particle-containing steam which improves the gasification rate and efficiency in the gasification of coal, biomass, and garbage.

Abstract: A method for preparing high-temperature, active particle-containing steam. The method includes: 1) preparing steam; selecting one or several non-oxidizing gases as a working gas; ionizing the working gas into a plasma working medium by using a plasma generator; and 2) injecting the plasma working medium into a high-temperature steam generator to form high-temperature ionized environment while introducing the steam into the high-temperature steam generator for allowing the steam to contact with the plasma working medium so that the steam is heated and activated to form active particle-containing steam. A device for preparing the high-temperature, active particle-containing steam is also provided.

Abstract: A method for preparation of amorphous silica from biomass. The method includes pyrolyzing the biomass under anaerobic conditions to yield a pyrolysis gas and solid residues, collecting the pyrolysis gas, and calcining the solid residues under aerobic conditions to yield amorphous silica.
