Zusammenfassung:	PROBLEM TO BE SOLVED: To obtain a method and an apparatus for separating nitrogen from nitrogen-containing hydrocarbon gas.SOLUTION: There are provided a method for separating nitrogen from hydrocarbon gas containing nitrogen and having methane as a chief ingredient, and an apparatus for separating nitrogen. The method and the apparatus for separating nitrogen from hydrocarbon gas containing nitrogen and having methane as a chief ingredient use a nitrogen adsorption and separation material comprised of strontium-exchange clinoptilolite. According to the method and the apparatus for separating nitrogen from nitrogen-containing hydrocarbon gas, the nitrogen in the nitrogen-containing hydrocarbon gas can be separated and removed for a long time.
