Embodiment 1

[0030] Take 10kg of FCC waste catalyst, add 10kg of ether to infiltrate according to the solid-to-liquid ratio of FCC waste catalyst to organic solvent 1:1, soak for 120min, and then put it in an oven at 80°C to instantly vaporize the ether infiltrated into the FCC waste catalyst Expansion, to achieve the purpose of removing the carbon deposits and impurities in the channels of the FCC waste catalyst; then put the FCC waste catalyst after the internal vaporization and expansion treatment in the muffle furnace, and use the high-temperature roasting air oxidation method to roast at 300 ° C for 1 hour, and the roasted FCC waste catalyst is used as a carrier, and the FCC catalyst after roasting and the sulfuric acid with a mass concentration of 5% are added in the reaction kettle with agitator, thermometer and reflux condenser to impregnate, and the sulfuric acid added and the roasted FCC waste catalyst after adding The liquid-solid ratio is 2:1, that is, the mass of sulfuric acid ...

Abstract

The invention discloses an internal vaporizing expansion method for regenerating a modified FCC waste catalyst and application thereof. The internal vaporizing expansion method is characterized by comprises the steps that 1, an FCC waste catalyst is wetted by using an organic solvent and then is put into a high-temperature drying oven or a muffle furnace of 80-100 DEG C to enable the organic solvent wetting and flowing into the FCC waste catalyst to be instantly vaporized and expand; 2, the FCC waste catalyst treated through the step 1 is subjected to roasting activation; 3, the FCC waste catalyst activated through the step 2 serves as a carrier, an impregnation method is adopted to load one of acid, alkali, metal ions. The modified FCC waste catalyst is used for esterification, condensation, cracking, hydrogenation and oxidation reaction. By means of the internal vaporizing expansion method, the FCC waste catalyst is utilized to prepare the modified and regenerated catalyst, the problem that a traditional FCC waste catalyst burying treatment method cause economic losses and soil, water and atmosphere pollution is solved, waste is turned into wealth, and dual benefits of economic value and environmental protection are obtained.

Description

technical field [0001] The invention relates to the regeneration and modification of solid waste in the petroleum refining industry and its application field, in particular to the regeneration and modification of FCC waste catalyst by an internal vaporization expansion method and its application. Background technique [0002] Fluid catalytic cracking (FCC) is the most important way to lighten heavy oil. The catalyst or catalyst used is the most widely used additive in the petroleum refining industry. Due to the heavy metals nickel (Ni), vanadium (V ) and iron (Fe) plasma deposition and deactivation due to carbon deposition, wear and other reasons, the total amount of waste FCC in the world's petroleum refining process is about 150-170kt / a. FCC waste catalyst, also known as FCC waste catalyst, the traditional landfill treatment method not only caused huge economic losses, but also caused serious pollution of soil, water and air. Industrially developed countries have explicit...
