A method can include reacting a stream including one or more C.sub.3 to C.sub.10 alkanes with bromine in a bromination reactor to form a bromination reactor discharge stream that includes alkylbromides and HBr. The method further includes coupling the alkylbromides in a coupling reactor to form a coupling reactor effluent comprising alkylbromides having between 5 and about 1000 carbon atoms, olefins having between 5 and about 1000 carbon atoms and HBr. The method also includes hydrogenating the alkylbromides having between 5 and about 1000 carbon atoms and olefins having between 5 and about 1000 carbon atoms to form alkanes having between 5 and about 1000 carbon atoms and HBr.

Disclosed are methods and systems for converting chloromethane to olefins. A method includes contacting an aluminosilicate catalyst having a chabazite zeolite structure with a feed that includes an alkyl halide and is substantially free of oxygenates under reaction conditions sufficient to produce an olefin hydrocarbon product comprising C.sub.2-C.sub.4 olefins.

A system and method for chemically destroying, degrading and incinerating a fluorocarbon or fluorinated material, such as perfluoroalkyl and polyfluoroalkyl substances (PFAS), with reduced emissions of gaseous PFC is provided. The method includes mixing the fluorinated material, a hydroxide base, and optionally a solvent system in a batch reactor to form a suspension. The PFAS and solvent system can be provided by AFFF. The reaction mixture is heated to a temperature ranging from about 25 C. to about 400 C. for about 0.5 hours to about 240 hours to defluorinate the fluorocarbons in the PFAS and produce a defluorinated waste product. More specifically, the method converts organic fluorine present in the PFAS to inorganic fluoride. Thus, the defluorinated waste product can be incinerated with reduced emissions of harmful gaseous PFCs.
