About Reactor Resources

Reactor Resources (RxR) specializes in providing first class solutions for all of your catalyst sulfiding and sulfur chemical needs. RxR helps our clients produce high quality Hydrocarbon Fuels, Renewable Diesel Fuel, Sustainable Aviation Fuel (SAF), and Petrochemicals. We are not satisfied with being a “me-too” type of company. Instead, our team brings true innovation to the industries that we serve. This “outside the box” thinking is illustrated by numerous developments including our patented SmartSkid Injection System, Online H2S Analyzer SystemTotal Sulfur Analyzer System, and Hydrogen Purity Analyzer.  Combining our skilled technicians and advanced technologies allows Reactor Resources top deliver cost efficient sulfiding services with the highest level of safety, accuracy, and reliability.

Our latest patented innovation is the use of MDEA to replace ammonia during startups with hyperactive hydrocracking and renewable fuels catalysts. Once introduced to the reactor, MDEA decomposes to form ammonia that will then moderate the activity of highly acidic catalysts. With a Health Hazard Rating of 1 (the lowest rating), MDEA is much safer to use and easier to handle than ammonia (HHR of 3). In addition, we now have an Online pH Analyzer System to measure the pH of water coming from the separator boot. Accurate and timely pH data allows for precise control of the nitrogen injection.

Reactor Resources Company History

Since forming Reactor Resources in 2011, our goal has been to provide the absolute best catalyst sulfiding services and sulfur products to the refining and petrochemical industries.  In our first year, we partnered with ChevronPhillips Chemical Company to supply Dimethyl Sulfide (DMS) to ethylene producers for passivating steam cracker furnace tubes. In 2012, RxR designed and built our first patented SmartSkid™ Injection System, bringing the sulfiding process into the 21st century. In addition, Reactor Resources was the first to introduce the use of an Online H2S Analyzer in place of pulling draeger tubes to measure the H2S recycle gas concentration during catalyst sulfiding. That year we also began supplying Dimethyl Disulfide (DMDS) and completed our first in-situ sulfiding projects. An Inline Hydrogen Purity Analyzer was added to our portfolio of gas analyzers in 2014.

In 2017, Reactor Resources began offering our sulfiding service package to customers in Europe and the Middle East from our office/shop near Rotterdam, The Netherlands. The following year, RxR acquired a European leader in catalyst activation services, Actisulf SAS of Tarbes, France. Actisulf is now part of Reactor Resources Europe.

Our clients have now used our personnel and systems to successfully sulfide over 1,000 hydrotreating, hydrocracking, and renewable fuel units with DMDS and/or TBPS.
