| titleOfInvention | Acidic ion buffer solution catalyst, preparation method thereof, and system and method for preparing furfural by using catalyst |
| abstract | The invention relates to an acidic ionic buffer solution catalyst which is a colorless transparent solution and comprises n mol of ammonium sulfate and n-1.1 n mol of 98% concentrated sulfuric acid, wherein the mass percentage of the ammonium sulfate and the sulfuric acid in the whole solution is 20-70%. The invention also discloses a preparation method of the catalyst, application of the catalyst to a furfural preparation process, and a method for preparing furfural by using hemicellulose or xylose raw material liquid, wherein the method uses the catalyst. The invention also discloses a system for preparing furfural by utilizing the hemicellulose or xylose raw material liquid, which comprises a static mixer, a reaction extraction tower and a rectifying tower system, wherein the water phase of the reaction extraction tower is the hemicellulose or xylose raw material liquid mixed by the static mixer and the catalyst, the oil phase is a solution capable of extracting the furfural component from the water phase, and the rectifying tower system separates the furfural component from the oil phase extracted with the furfural component. The invention has high extraction efficiency, low cost and good economic benefit. |
