Disclosed is a process for producing a fatty alkyl ester and glycerin, including step 1 of reacting fats and oils with C1 to C5 lower alcohols, step 2 of removing the lower alcohols discharged from the outlet of a rector in step 1 until the lower alcohol content is reduced to 8 wt % or less, step 3 of separating the product obtained in step 2 into oil and aqueous phases, step 4 of reacting the oil phase obtained in step 3 with lower alcohols in the presence of an acid catalyst, and step 5 of separating the product discharged from the outlet of a reactor in step 4 into oil and aqueous phases thereby giving fatty acid alkyl esters and glycerin, as well as a process for producing fatty alcohols from hydrogen and the fatty acid alkyl esters obtained in the above process.
