Embodiment 1

[0044] Preparation of carrier: used to illustrate the preparation method of the carrier provided by the present invention.

[0045] 1) Weigh 30g of zirconia, then take 0.525g of nitrogen-methylpyrrolidone, 1.4g of polyethersulfone, and 9.8g of polyvinylpyrrolidone, mix them into a dry and clean ball mill jar equipped with marbles, and mill the jar Fix it on the ball mill to prevent the ball mill tank from being thrown out when the ball mill is working due to loose fixation. After everything is completed, the ball mill will be milled at a speed of 400r / min for 4 hours to obtain a viscous slurry;

[0046] 2) Pour the slurry prepared in step 1) into a medical needle with a measuring range of 10ml, and use a medical needle with a measuring range of 10ml to drip out spherical bodies with a diameter of about 2mm, and drop them into a 500ml beaker filled with water. After dripping, place it in water for 12 hours to make its phase inversion complete. After the phase inversion is compl...

Abstract

The invention discloses a preparation method of a zirconium ball carrier, and application of the zirconium ball carrier to a manganese-based desulfurizing agent. During the preparation, zirconia is used as a carrier support body; polyether sulfone is used as a bonding agent; polyvinylpyrrolidone is used as a dispersing agent; through two-way substitution of N-methyl pyrrolidone and water, a sphere is formed by a wet process in water; after high-temperature sintering, a spherical wear-resistant carrier of a porous structure is formed, i.e., the zirconium ball carrier is obtained. A bran-new carrier preparation method is used; the porous wear-resistant spherical carrier is prepared by a phase inversion method; the spherical carrier is suitable for the preparation of all impregnated catalysts; the problems that the air resistance of a conventional powder catalyst is great, so that the spherical carrier can be swept and taken away by airflow during experiment, and the like are solved. When the carrier is used for preparing a high-temperature manganese-based desulfurizing agent, a high-precision renewable desulfurizing agent is obtained; the desulfurizing agent can be used for removing H2S in an IGCC (Integrated Gasification Combined Cycle); the technical support is provided for electric field electricity generation of an SOFC (Solid Oxide Fuel Cell) with high energy utilization efficiency.

Description

technical field [0001] The invention relates to a preparation method of zirconium ball carrier and its application in manganese-based desulfurizer. Background technique [0002] The traditional energy structure and its utilization methods are increasingly difficult to meet the needs of human survival and development. Faced with the severe challenges of development and environmental protection, all countries in the world are committed to finding new technologies for sustainable energy utilization that can replace traditional energy utilization models to meet the growing needs of huge energy consumption while reducing pollution. The purpose of purifying the environment. [0003] The basic way to efficiently and rationally use non-renewable energy resources while maintaining environmental and ecological balance is to develop fuel cell technology that uses these resources as primary fuels. A solid oxide fuel cell is a power generation device that converts chemical energy store...
