Problems solved by technology

Currently, the vehicles on the market use National III technology catalysts. The direct application of National III catalysts on National IV motorcycles mainly has the following two problems: 1. The emission content cannot meet the pollutant emission limits of National IV motorcycles.
2. National III requires a durable mileage of 1.2W kilometers (50≤displacement<150cc), and National IV requires a durable mileage of 2W kilometers (50≤displacement<150cc). National III catalyst durability mileage cannot meet the requirements of National IV

Embodiment Construction

[0024] Preferred embodiments of the present invention are described below, and it should be understood that the preferred embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.

[0025] 1. Making slurry

[0026] 1. Production of inner layer slurry

[0027] The dry slurry composition is measured by mass fraction: Al2O3 (20%-50%), CeZrO2 (30%-60%), the precursor of cerium, measured as CeO2 (2%-10%), the precursor of zirconium, measured as ZrO2 Metering (2%-10%), the precursor of vanadium, metering with BaO (2%-10%), add deionized water to the container and stir, then put Al2O3 into the container and stir for more than 30min, then add cerium nitrate (CeO2 ), zirconium acetate (ZrO2), barium acetate and stir for more than 30min. Add PdNO3 (Pd) and stir for more than 1h, add CeZrO2 and stir for more than 1h. Adjust pH=3~6. Add polyethylene glycol and stir for more than 30 minutes, add a smal...

Abstract

The invention discloses a novel motorcycle catalyst. The catalyst comprises a carrier, and an inner layer slurry and an outer layer slurry which are coated on the carrier; the inner layer slurry comprises, by mass, 20-50% of Al2O3, 30-60% of CeZrO2, 2-10% of a cerium precursor (by CeO2), 2-10% of a zirconium precursor (by ZrO2) and 2-10% of a vanadium precursor (by BaO); and the outer layer slurrycomprises, by mass, 30-60% of Al2O3, 30-50% of a CeZrO2 complex oxide, 2-10% of the cerium precursor (by CeO2), 2-10% of the zirconium precursor (by ZrO2) and 2-10% of the vanadium precursor (by BaO). The novel motorcycle catalyst can effectively reduce the content of motor emissions, prevent the pollution of the motor emissions to the environment and improve the air quality of the environment.

Description

technical field [0001] The invention relates to a novel motorcycle catalyst and a manufacturing method thereof. Background technique [0002] On August 22, 2016, national standards GB 14622-2016 "Motorcycle Pollutant Emission Limits and Measurement Methods (China Phase IV)" and GB 18176-2016 "Mobile Motorcycle Pollutant Emission Limits and Measurement Methods (China The fourth stage)" (hereinafter referred to as "National IV Emission Standard") was officially released, the purpose is to implement the "Environmental Protection Law of the People's Republic of China" and the "Law of the People's Republic of China on Air Pollution Prevention and Control" to prevent motorcycle emissions from polluting the environment. Improving the ambient air quality and forcing industrial transformation and upgrading through the revision of emission standards will put forward higher technical requirements for the development and production of motorcycle products in my country in the next stage.
