Abstract
Provided is a gasoline production device capable of effectively using heat of reaction generated in the synthesis of gasoline and also capable of readily cooling heat generated by synthesizing gasoline. A device 30 for producing gasoline from methanol includes a plurality of reaction tubes 34 configured to synthesize gasoline from methanol and a duct 36 configured to allow air to flow outside the reaction tubes, and heat exchange is carried out between synthesis heat generated within the reaction tubes 34 and the air which flows through the duct 36.
Claims5
A device for producing gasoline, comprising:
- reaction tubes for synthesizing gasoline from methanol, wherein two types of catalysts including a dimethyl ether synthesis catalyst for synthesizing dimethyl ether from methanol and a gasoline synthesis catalyst for synthesizing gasoline from dimethyl ether are charged inside the reaction tube in two stages;
- and
- a duct which allows air to flow outside the reaction tubes,
- wherein heat exchange is carried out between synthesis heat generated in the reaction tubes and the air that flows through the duct, and
- wherein the duct is configured so as to allow the air to flow outside a portion of the reaction tubes in which the dimethyl ether synthesis catalyst is charged and then flow outside a portion of the reaction tubes in which the gasoline synthesis catalyst is charged.
