In the complex world of petroleum refining, catalyst performance is paramount. The efficiency and longevity of hydrogenation catalysts, in particular, heavily depend on proper pre-sulfidation. For years, Dimethyl Disulfide (DMDS) has been a common choice, but its inherent drawbacks – strong odor, toxicity, and handling challenges – have driven the industry to seek superior alternatives. This is where Di-tert-butyl Polysulfide (DTBPS) emerges as a game-changer, offering a safer, more effective solution for refiners. As a prominent manufacturer and supplier of industrial chemicals, we are proud to offer DTBPS, a chemical that redefines standards in catalyst activation.

DTBPS, also known by its CAS number 68937-96-2, is specifically engineered to provide a high sulfur content and exceptional purity, making it an ideal pre-sulfiding agent. Unlike DMDS, DTBPS is characterized by its low odor and non-volatile nature, significantly improving workplace safety and simplifying logistics. This means that when you buy DTBPS, you are investing in a product that is not only highly effective but also easier and safer to store, transport, and use. This makes it a preferred choice for procurement managers and R&D scientists alike who prioritize both performance and safety.

The application of DTBPS in hydrogenation units is particularly noteworthy. During the pre-sulfidation process, DTBPS effectively converts the metal oxide species within catalysts into active crystalline metallic sulfide phases. This in-situ sulfidation process, when managed correctly, prevents catalyst poisoning and avoids exothermic reactions that can lead to catalyst sintering. The wide molecular weight distribution of DTBPS allows for a broader decomposition temperature range during sulfidation, giving operators greater control and preventing localized overheating. Furthermore, its decomposition products are small molecular hydrocarbons, which do not contribute to catalyst coking or contamination. This meticulous control over the sulfidation process ensures that your catalysts achieve their maximum potential, leading to enhanced operational efficiency and extended catalyst life.

Beyond its role in catalyst activation, DTBPS also serves as an excellent anti-coking agent in ethylene cracking units. By preventing coke formation, it helps maintain the integrity of the cracking equipment, reduces downtime for cleaning, and ensures consistent product output. This dual functionality makes DTBPS a highly versatile chemical for the petrochemical industry.
