The Ultimate Polysulfide Solution for Catalyst Sulfidation

In the world of petroleum refining and petrochemicals, catalyst performance is paramount. To ensure maximum efficiency, stability, and longevity, catalyst activation through sulfidation is crucial. Enter DTBPS (di-tert-butyl polysulfide) or TBPS, an innovative polysulfide compound that is revolutionizing the way catalysts are treated before use.

DTBPS or TBPS is a specialized agent designed to provide the most effective and controlled sulfidation process for catalytic systems. It ensures optimal performance in key refining processes such as hydrocracking, catalytic cracking, and hydrotreating. By forming a protective sulfur layer on the catalyst surface, DTBPS or TBPS significantly enhances the catalyst’s activity and resistance to deactivation, resulting in longer operational life and higher throughput.

One of the most compelling reasons to incorporate DTBPS or TBPS into your catalyst preparation process is its ability to create a stable sulfurized surface quickly and efficiently. This not only maximizes catalyst efficiency but also minimizes the risk of catalyst poisoning from impurities that may be present in feedstock. With DTBPS or TBPS, refineries are able to streamline their operations, improve the quality of refined products, and optimize overall plant performance.

Furthermore, DTBPS or TBPS’s versatile and high-performance nature makes it suitable for a wide range of refining and petrochemical processes. Whether you’re dealing with heavy crude oil or more complex feedstocks, this polysulfide is a key tool in ensuring that your catalytic systems perform at their peak.

In today’s competitive energy market, operational efficiency is key. By choosing DTBPS or TBPS, you are ensuring that your catalysts perform at their highest capacity, reduce downtime, and increase product yields, all while protecting the environment by minimizing emissions and waste.

Upgrade your catalyst sulfidation process with DTBPS or TBPS and see the difference in your refining operations. With DTBPS or TBPS, expect enhanced catalyst stability, longer service life, and superior overall performance.

Recently, Junyuan Petroleum Group has developed DTBPS (Di-tert-butyl Polysulfide) environmentally friendly and safe vulcanizing agent, which has the characteristics of no odor, low odor, high flash point, strong safety performance, and significant intrinsic safety characteristics. It has become an ideal green and reliable substitute for traditional dimethyl disulfide (DMDS) vulcanizing agent products.

It is understood that dimethyl disulfide is widely used as a pre sulfurization catalyst, sulfur injection for sulfur supplementation, and coking inhibitor for ethylene cracking in industry. Due to its good oil solubility and high sulfur content, it is widely used. However, it has strong irritancy, suffocating odor, toxicity, high risk factor, and high cost, which brings enormous pressure to the hydrogenation industry.

Based on this, Junyuan Petroleum Group has developed DTBPS (Di-tert-butyl Polysulfide) environmentally friendly and safe vulcanizing agent through collaborative innovation between industry, academia, and research. The flash point of this vulcanizing agent is over 100 ℃, which belongs to non flammable materials and greatly reduces potential production, transportation, and storage risks. Moreover, the decomposition temperature is low, and it can be injected into the system at around 160 ℃ to participate in the vulcanization reaction, increasing the activity of the catalyst and shortening the vulcanization time.
