Abstract
The invention provides a method for decomposing sulfur-fluorine-containing compound and apparatus thereof. Sulfur-fluorine-containing compound is decomposed in two steps, comprising contacting the compound with a first catalyst such as a monometallic catalyst and a second catalyst such as a bimetallic catalyst, and at a low reaction temperature to produce resulting compounds capable of water-solubility. Then, the resulting compounds, namely sulfur- or fluorine-containing compounds, are removed by washing.
Claims20
A method for decomposing sulfur-fluorine-containing compound, comprising:
- contacting a sulfur-fluorine-containing compound with a first catalyst comprising a monometallic catalyst;
- decomposing the sulfur-fluorine-containing compound to produce a first decomposition;
- and
- contacting the first decomposition with a second catalyst comprising a bimetallic catalyst to decompose and produce a second decomposition capable of water-solubility.
An apparatus for decomposing sulfur-fluorine-containing compound, comprising:
- a first reactor having a first inlet for providing a sulfur-fluorine-containing compound for contacting with a first catalyst therein to decompose and produce a first decomposition and a first outlet for leading the first decomposition out of the first reactor;
- and
- a second reactor having a second inlet for providing the first decomposition for contacting with a second catalyst therein to decompose and produce a second decomposition and a second outlet for leading the second decomposition out of the second reactor;
- wherein the first outlet connects to the second inlet to lead the first decomposition into the second reactor.
