Title:
MONOLITHIC CATALYST PREPARATION METHOD EMPLOYING 3D PRINTING, AND APPLICATION OF MONOLITHIC CATALYST
Document Type and Number:
WIPO Patent Application WO/2021/022848
Kind Code:
A1
Abstract:
A monolithic catalyst preparation method employing 3D printing, and an application of a monolithic catalyst in oxidative desulfurization of fuel oil. The method comprises: printing a three-dimensional model using a light-curing printer, and then performing carbonization at a high temperature; and loading a formed three-dimensional carbide with phosphotungstic acid so as to prepare and obtain a monolithic catalyst for deep oxidative desulfurization by means of 3D printing. The prepared catalyst can be easily separated from oil after the reaction has ended, and the operation is simple. Moreover, the catalyst facilitates the removal of sulfides such as DBT, 4-MDBT, and 4,6-DMDBT from model oil, and provides good catalytic performance and cycle performance.
