a method of and apparatus for cracking methanol , for utilizing the cracked - methanol to operate a minimum - pollution fuel - combusting device . the heat of combustion gases which is brought into the presence of a catalyst is employed to crack the methanol into hydrogen gas and carbon monoxide gas . the hydrogen gas and carbon monoxide gas thereupon serve as the primary fuel source for the fuel - combusting device and these gases , or hydrogen alone , are further utilized to create a reduction atmosphere so as to render the heated combustion gases inert and pollution - free to discharge into the ambient atmosphere .
