대표독립항:
1. A propellant disposal device for a propulsion system comprising:
a carry-in unit configured to supply propulsion systems;
a cutting unit arranged for a process subsequent to that of the carry-in unit, and configured to individually receive the propulsion systems that are on standby at the carry-in unit and cut two opposite ends of the received propulsion system;
a propellant extraction unit arranged for a process subsequent to that of the cutting unit, and configured to insert an extraction tool into the cut ends of the propulsion system and extract the propellants charged within the propulsion system;
a return unit configured to sequentially deliver the propulsion system to the corresponding process positions; and
a propellant delivery unit having its end portion located below the cut end of the propulsion system where the extraction tool is inserted, and configured to deliver the extracted propellants to a preset location for discharge.

발명의 명칭: Method and apparatus for producing disilane through pyrolysis of monosilane
대표도면:
대표독립항:
1. An apparatus for producing disilane through pyrolysis of monosilane, comprising:
a monosilane pyrolysis unit configured to pyrolyze monosilane and produce disilane and higher silanes, the pyrolysis unit having a pyrolysis temperature of 400-460ºC., a pyrolysis pressure of 3-5 bar and a pyrolysis gas space velocity of 60-500 hr-1;
a solid particle removal unit configured to remove particles produced by the pyrolysis unit, the solid particle removal unit comprising a metal filter for removing particles exceeding 0.1μm in diameter, and a ceramic support provided behind the metal filter for removing particles of 0.1μm or smaller in diameter;
a condensing unit configured to condense and liquefy, after said removal of particles, unreacted monosilane, and disilane and higher silanes with three (3) to seven (7) silicon atoms produced as results of the pyrolysis by the pyrolysis unit, excluding hydrogen from a gas with the solid particles removed by said solid particle removal unit;
a first separation unit configured to separate monosilane from a mixture of the liquefied unreacted monosilane, disilane and higher silanes; and
a second separation unit configured to separate disilane from the resultant mixture containing disilane and higher silanes with three (3) to seven (7) silicon atoms.
