Hydrogen-assisted cloud point depressant catalyst is an advanced catalytic material designed to modify the molecular structure of fuel components, lowering the cloud point and improving cold flow properties. Engineered with optimized hydrogenation techniques, it enhances wax isomerization, reduces crystallization effects, and ensures prolonged operational efficiency in industrial fuel refining processes. This catalyst is widely used in diesel fuel upgrading, aviation fuel optimization, and petrochemical refining, delivering superior performance in controlled hydrogen-assisted molecular modification.
Product Overview
The Hydrogen-Assisted Cloud Point Depressant Catalyst is a shape-selective catalytic cracking catalyst specifically designed for the hydrogen-assisted cloud point reduction process. Its core component is the ZSM-5 zeolite. The reaction mechanism of this catalyst is similar to traditional catalytic cracking, with the cracking reactions occurring on protonic acid centers, following the carbocation reaction mechanism. The special structure of the ZSM-5 zeolite, with its intersecting linear and zigzag channels, is ideal for the selective cracking of small-chain alkanes and alkylated alkanes, reducing high cloud point components and effectively lowering the pour point of the oil. This catalyst is widely used to produce clean fuel-grade low-cloud-point diesel, offering a strong depressant effect on the cloud point.
Key Features
- Selective Cracking: The microporous structure of ZSM-5 zeolite allows only small-chain alkanes to enter, selectively cracking alkanes and lowering the oil's cloud point.
- Improved Diesel Quality: By selectively reducing high cloud-point components, the catalyst optimizes diesel fractions, ensuring that the product meets low-cloud-point diesel standards.
- Strong Stability: The catalyst has high thermal and chemical stability, maintaining excellent catalytic performance under high-temperature and high-pressure conditions.
- Wide Adaptability: It is suitable for processing high-wax content straight-run diesel, as well as lower-quality catalytic and coking diesel, improving the quality of feedstock oils.
- Enhanced Fuel Performance: Effectively improves the low-temperature fluidity of diesel fuel, enhancing its clean fuel performance.
Applications
- Low-Cloud-Point Diesel Production: Widely used in the production of clean fuel-grade low-cloud-point diesel, meeting environmental and automotive fuel standards.
- Catalytic Dewaxing Process: Applied in catalytic dewaxing processes to remove high-cloud-point wax components, improving diesel flow properties.
- Oil Refining: Suitable for refining diesel, especially for hydrogen-assisted cloud point reduction treatment of high-wax content straight-run diesel, catalytic diesel, and coking diesel.
- Clean Fuel Processing: Used in the processing of clean fuels to improve low-temperature performance, meeting low-emission and low-cloud-point requirements.
