Reactor Resources

Catalyst Sulfiding and Supply of Sulfur Chemicals

Reactor Resources (RxR) is a leading supplier of sulfur chemicals and sulfiding services for refinery, renewable fuels, and petrochemical applications. Our company was formed in 2011 with the goal of establishing a new standard in catalyst sulfiding. Subsequently, Reactor Resources has grown to provide chemicals, catalyst activation services, and gas monitoring to refineries and pet-chem plants throughout the world. Specifically, we now service clients in North America, Europe, the Middle East, and Asia.


Our home office is located south of Houston, Texas in the city of Alvin. In October 2018, we acquired Actisulf SAS in Tarbes, France. Eventually, Actisulf transitioned to become Reactor Resources France. This acquisition expanded our capabilities to service customers in Europe and the Middle East. In addition, we have a European Office in the city of Poortugaal near Rotterdam, The Netherlands.

Catalyst Sulfiding Experience

Owing to the advancements we have made in the field of catalyst activation, RxR has now sulfided over 1000 hydrotreating and hydrocracking units. We provide turn-key sulfiding services including the supply and delivery of the sulfur chemistry, rental of chemical injection equipment and gas analyzers, and fully trained technicians to set up and operate the equipment 24/7. Our innovations, such as Cloud-based Telemetry and Online Gas Analysis, are now standard operating procedure for almost all of our clients.

Sulfiding Chemicals

We are the only sulfiding company that offers both Dimethyl Disulfide (DMDS) and di-Tertiary Butyl Polysulfide (TBPS 454 and/or Sulfrzol® 54) as spiking agents for catalyst sulfiding.  This uniquely qualifies RxR to assist you when deciding on the best spiking agent for your sulfiding project.

MDEA and Ammonia Injection

In 2015, RxR pioneered the use of MDEA (methyldiethanolamine) as a nitrogen passivating agent for hydrocracking catalysts and renewable fuels catalysts. MDEA is a safe and cost effective alternative to ammonia and is much easier to handle and pump.


Reactor Resources is a leading supplier of Dimethyl Sulfide (DMS) and Dimethyl Disulfide (DMDS) to ethane steam crackers. In order to passivate the furnace tubes and control CO formation, DMS or DMDS is injected into the process to form H2S. RxR has technical experts for steam cracker sulfur injection that can support optimization of your DMS or DMDS injection.

Renewable Fuels

Finally, Reactor Resources has started up and supplied more Renewable Fuels Units than any other company across the globe. Let us help you get your renewables unit up and running at peak efficiency.
