Spilled oil adsorption product based on spent catalytic cracking catalyst

Abstract

The invention provides a spilled oil adsorption product based on a spent catalytic cracking catalyst. The spilled oil adsorption product is prepared from spent catalytic cracking catalyst powder, an oil-absorbing waterproof packaging material and further a light-weight foam material, wherein the spent catalytic cracking catalyst powder is hermetically packaged in the oil-absorbing waterproof packaging material and is prepared by ball milling, the specific surface area of the spent catalytic cracking catalyst powder is 100-300 m<2> / g, the light-weight foam material can be better used for absorbing spilled oil on the water surface, and the oil-absorbing waterproof packaging material can select and use reinforced polypropylene, polyester, nylon, spandex or acrylic non-woven fabrics and can bemade into a bag shape, a pie shape, a strip shape or a sheet shape. The spilled oil adsorption product prepared through a physical method has the advantages that the spent catalytic cracking catalystdoes not need to be subjected to chemical or thermal treatment, energy conservation and environmental protection are realized, the cost is low, use and cleaning are convenient, the adsorption capability is high, and high-value resource utilization of the spent catalytic cracking catalyst is realized.

Description

technical field [0001] The invention relates to the field of oil spill adsorption, in particular to an oil spill adsorption product based on catalytic cracking waste catalyst. Background technique [0002] In my country, the amount of catalytic cracking catalysts accounts for about 85% of the total amount of refining catalysts. After the catalytic cracking catalysts are repeatedly regenerated and used in this device, some catalysts are destroyed by the hydrothermal environment due to the molecular sieve structure or due to the excessive adsorption of heavy metals and carbon deposits. , will be irreversibly deactivated and discharged. This part of the discarded catalytic cracking spent catalyst is included in the "National Hazardous Waste List" and belongs to hazardous waste. In my country, the annual production of catalytic cracking spent catalysts is about 100,000 tons. In order to prevent environmental pollution, it must be disposed of in a harmless manner or utilized as a ...
