Document Type and Number:
Japanese Patent JP7432214
Kind Code:
B2
Abstract:
[Problem] To provide a urea production device and a urea production method with which it is possible to produce urea under conditions which do not require a high temperature or high pressure, and using carbon dioxide and ammonia as starting materials. [Solution] This urea production device 1 comprises: a main body which comprises a dielectric; a first electrode 3 which is disposed inside of the main body 2; and a second electrode 4 which is external to the main body 2 and is disposed such that at least a portion thereof is opposite the first electrode 3. The urea production device 1 also comprises a gas flow path 11 formed between the main body 2 and one electrode from between the first electrode 3 and the second electrode 4, a first starting material introduction path 12 connected at one end to the gas flow path 11 and connected at the other end to a carbon dioxide storage supply 7, and a second starting material introduction path 13 which is a different starting material introduction path from the first starting material introduction path 12, is connected at one end to the gas flow path 11, and is connected at the other end to an ammonia storage source 8. A voltage is applied between the first electrode 3 and the second electrode 4, and electric discharge can be generated. Additionally, the present invention provides a urea production method using said urea production device 1.
