Abstract
In the method of the present invention for producing fatty acid alkyl ester and/or glycerin, as a heat source for an alcohol refining step of refining alcohol from unreacted alcohol that remains without reacting in a first reaction step, at least a part of heat of the unreacted alcohol is used. This allows reducing costs in production of fatty acid alkyl ester and/or glycerin over a solid catalyst.
Claims21
A method for producing fatty acid alkyl ester and/or glycerin, comprising:
- a first reaction step of reacting fat and oil with alcohol over a solid catalyst;
- a first alcohol stripping step of evaporating, from a first reaction liquid obtained in the first reaction step, unreacted alcohol that remains without reacting in the first reaction step;
- and
- an alcohol refining step of refining the alcohol from the unreacted alcohol with use of at least a part of heat of the unreacted alcohol.
A device for producing fatty acid alkyl ester and/or glycerin, comprising:
- a reactor for reacting fat and oil with alcohol over a solid catalyst;
- a stripper for stripping, from a reaction liquid obtained in the reactor, unreacted alcohol that remains without reacting in the reactor;
- and
- a refiner for refining the alcohol from the unreacted alcohol stripped in the stripper, with use of at least a part of heat of the unreacted alcohol.
