A method of preparing silicon using silica includes placing silica in a reaction chamber; adding a reducing agent into the reaction chamber; feeding a material for impact into the reaction chamber and sealing the reaction chamber; and reducing the silica to silicon by allowing the material for impact to generate a physical impact inside the reaction chamber. The preparation method of silicon using silica does not employ a high-temperature high-pressure process and provides a preparation method of silicon by which the porous structure of the silica before a reduction reaction is maintained within the silicon even after the reaction.

A gasifying apparatus including a variable gasifier and used as both a power generator and a combustion boiler and a method of driving the same are disclosed. A combustion boiler and a generator engine, driven with synthesis gas, are associated with a single gasifier, and the gasifying apparatus produces synthesis gas proper to a technical field of the gasifier by selectively applying an upflow gasifier and a downflow gasifier according to the technical field of the gasifier.

A hydrogen sulfide and carbonyl sulfide removal method using microwave plasma comprising a hydrogen sulfide and carbonyl sulfide containing mixed-gas supplying step, a microwave supplying step, a plasma flame forming step, a hydrogen sulfide and carbonyl sulfide decomposing step in which hydrogen sulfide and the carbonyl sulfide are dissociated into atomic units, a rebinding step in which atomic units are rebound so that combustible gases are generated, and a separately collecting step in which the gases are separated and then are separately collected.

Hydrogen sulfide and carbonyl sulfide removal apparatus using microwave plasma, and method thereof

Provided are an apparatus and a method for rapidly producing a synthetic gas from a bio-diesel byproduct using microwave plasma, in which, while a plasma flame is generated by a plasma generator and waste glycerin, a bio-diesel byproduct, as fuel, is gasified by being supplied to the generated plasma flame of high temperature, the fuel is supplied in various types to increase the contact time or the contact area with the plasma flame and thus promote gasification thereof and the contents of steam and oxygen supplied and the plasma power are controlled to increase the collection amount of combustible gas and thus allow rapid production of the synthetic gas.
