■ Product Overview

This multifunctional metal passivator is designed specifically for catalytic cracking units, aiming to effectively address the negative impact of heavy metal impurities in crude oil on catalyst performance. It can react with heavy metals such as nickel, vanadium, and iron in crude oil through specific chemical reactions, converting them into chemically stable compounds, thereby reducing the toxicity of heavy metals to catalysts, maintaining catalyst activity and selectivity, ensuring stable and efficient operation of catalytic cracking units, improving light oil yield, and reducing production costs.

■ Product Features

Efficient passivation: The unique formula gives it strong passivation ability against various common heavy metals. It can quickly react with heavy metals, fix them in a short period of time, prevent their damage to the catalyst, effectively improve the service life of the catalyst, and extend the operating cycle of the device.

Multi functional collaboration: Not only can it passivate heavy metals, but it also has a certain anti coking function, which can reduce carbon deposition on the catalyst surface and further optimize the performance of the catalyst. At the same time, it has a certain corrosion inhibition effect on the equipment inside the device, reducing the risk of equipment failure caused by heavy metal corrosion.

Wide applicability: Suitable for various catalytic cracking units, whether processing light crude oil or heavy crude oil, it can stably function under different reaction temperature, pressure, and catalyst oil ratio conditions. Good compatibility with catalysts and other additives inside the device, without interfering with the normal reaction process.

Quick dispersal: Has excellent dispersibility, can quickly diffuse evenly in crude oil, ensures sufficient contact and reaction with heavy metals, and improves passivation effect. Even in complex crude oil systems, it can quickly reach the site of action and exert its function.

Safety and Environmental Protection: The product uses environmentally friendly raw materials that comply with relevant safety and environmental standards. During use, it ensures the safety of operators and poses minimal environmental hazards. After use, there will be no residual harmful substances in the device or environment, making it easy to handle and in line with the development requirements of green refining.

■ Scope of application

This multifunctional metal passivator is suitable for catalytic cracking units in various refineries, mainly used for:

Riser reactor: During the contact reaction between raw oil and catalyst, passivators can react with heavy metals in crude oil in a timely manner, preventing the damage of heavy metals to the active centers of the catalyst and ensuring the efficient progress of the reaction.

Regenerator: During the catalyst regeneration process, passivators can continue to play a role in reducing the damage of heavy metals to the catalyst structure in high-temperature environments, maintaining the activity recovery efficiency of the catalyst, and ensuring the stable operation of the regenerator.

Catalyst circulation system: Throughout the entire catalyst cycle, the passivator continuously provides protection to the catalyst in circulation, ensuring that the catalyst maintains good performance at all stages of the device.
