Abstract
Disclosed is a process for producing alkyl fatty esters from fats/oils and C1 to C5 lower alcohols by a multistage reaction process, which includes feeding fats and oils to a reactor at an upper stage and then sent to a stage at the downstream side while feeding lower alcohols to a reactor at a lower stage, and simultaneously returning lower alcohols recovered from an outlet of the reactor to a stage at the upstream side, thereby repeating the reaction.
