GDS-56 is Di-tert-butyl polysulfide (sulfurized isobutylene) and is a new generation of Catalyst Sulfiding Agent (equivalent to SulfrZol® 54 of Lubrizol), primarily used as a sulfiding agent for hydrotreating catalysts. It overcomes all the disadvantages of dimethyl disulfide (DMDS) and represents a superior alternative sulfiding agent. In addition, this product can be used as a coking inhibitor for ethylene cracking furnaces and as a sulfur solvent in oil and gas field operations.
Features
• High sulfur content
• Low odor
• Flash point above 100 °C, with no risk of flash fire or explosion
• Safe and clean during handling, storage, and transportation
• Hydrogen utilization up, SOx emissions down.
Packaging and Storage
Packaging:Available in 200-L steel drums, 1000-L IBC containers, or 20,000-L tank containers.
Storage:Store in a dry, well-ventilated warehouse at ambient temperature, protected from light (especially when using transparent or semi-transparent containers).
