Abstract
One aspect of the present disclosure provides a system for producing 1,3-butadiene, which includes: a first supply unit, by which a first feed including a butene raw material, oxygen and steam is supplied; a second supply unit, by which a second feed including a butene raw material and oxygen is supplied; and a reaction unit, which includes a catalyst fixed bed and in which an oxidative dehydrogenation reaction takes place, wherein the first supply unit is connected to a front end of the reaction unit, and the second supply unit is connected to an intermediate end of the reaction unit.
Claims11
A system for producing 1,3-butadiene, the system comprising:
- a first supply unit configured to supply a first feed including a butene raw material, oxygen and steam;
- a second supply unit configured to supply a second feed including a butene raw material and oxygen;
- and
- a reaction unit, which includes a catalyst fixed bed and in which an oxidative dehydrogenation reaction is to be taken place,
- wherein the first supply unit is connected to a front end of the reaction unit, and the second supply unit is connected to an intermediate end of the reaction unit, and
- wherein the first feed supplied by the first supply unit includes the butene raw material in an amount of 40% to 90% by volume relative to a total amount of the butene raw material supplied to the system.
A method for producing 1,3-butadiene in a system, the method comprising:
- supplying, by a first supply unit, a first feed including a butene raw material, oxygen and steam:
- supplying, by a second supply unit, a second feed including a butene raw material and oxygen;
- and
- allowing an oxidative dehydrogenation reaction to take place in a reaction unit including a catalyst fixed bed,
- wherein the first supply unit is connected to a front end of the reaction unit, and the second supply unit is connected to an intermediate end of the reaction unit, and
- wherein the first feed supplied by the first supply unit includes the butene raw material in an amount of 40% to 90% by volume relative to a total amount of the butene raw material supplied to the system.
