With 40+ years of experience, technical expertise and understanding of the science, Johnson Matthey stands by our performance guarantees.
Johnson Matthey’s PURASPEC™ absorbents are the industry choice for longest bed life and toughest duties. PURASPEC technology utilises metal salts specially engineered into robust granules to remove traces of contaminants from hydrocarbon gases and liquids. In particular, these absorbents are designed to remove a range of sulphur compounds, heavy metals and halides.
PURASPEC are made-to-measure absorbent solutions that fit right, feel great and last the distance. They are widely used for natural gas sweetening to meet pipeline or liquefaction specifications and are designed to remove mercury and a range of sulphur compounds – most frequently hydrogen sulphide (H₂S) and carbonyl sulphide (COS). Within an oil refinery, PURASPEC solutions are used to purify hydrocarbon feeds for motor gasoline and aromatics production by removing sulphur and chloride-based impurities.
PURASPEC high capacities lead to less change-outs and waste, minimising the cost of impurity removal over time. The fixed-bed processes are simple to operate and require low capital outlay. Our latest generation products can extend the bed life or reduce space requirements for the vessel.
✔ Cost management
Our customers can depend upon PURASPEC performance to effectively remove impurities, which has already been proven with hundreds of installations worldwide at both onshore and offshore locations.
PURASPEC absorbents are flexible and withstand process upsets. Robust granules maintain stable pressure drop throughout the life of the absorbent allowing for minimal operators’ intervention. Energy use and CO₂ emissions during operation are effectively zero. Where possible, used absorbents are reprocessed and disposed of in an environmentally responsible way using Johnson Matthey’s PURASPEC™ service.
Catalytic oxidation solutions complement Johnson Matthey's absorption offer
Johnson Matthey’s PURAVOC™ technology provides a catalytic oxidation solution to remove a broad variety of volatile organic compounds (VOCs), oxygen, hydrogen and carbon monoxide from various gas stream sources. PURAVOC catalysts can be used in traditional chemical processes and emerging sustainable fuels and energy applications.
PURAVOC offers a range of platinum group metal (PGM) fixed bed catalysts, utilising our 200+ years expertise in PGM chemistry. They are specially designed to oxidise individual or complex gas impurities to very low levels, at low temperatures compared to thermal processing and with minimal intervention. As a result, PURAVOC can achieve long and dependable bed life at reduced operational expenditure, making this a very economical solution.

Sulphur removal absorbents
Our PURASPEC™ absorbents are proven over the last four decades to be a simple and effective solution to remove sulfur to very low concentrations within the gas processing, refining and petrochemical markets. These are also finding home in emerging sustainability and decarbonisation driven technologies such as renewable and recyclable feeds, and CCUS.
Mercury removal absorbents
Our PURASPEC™ range of absorbents are tailored for effective and complete mercury removal in gas and liquid phase duties. PURASPEC mercury absorbent portfolio combines decades of industry experience with the newest innovations in manufacturing technology.
Chloride removal absorbents
PURASPEC™ chloride absorbents offer a suite of customized solutions for Hydrogen chloride (HCl) removal and Organo-chlorides (RCl) removal.
Arsine removal absorbents
Our PURASPEC™ absorbents have proven over the last two decades to be highly effective and selective for the removal of arsine from light liquid hydrocarbon streams. These streams commonly originate from cracking of heavy hydrocarbon streams such as FCC or olefin steam cracking.
Johnson Matthey’s solution for COS removal is a two-stage process: an initial hydrolysis step to convert COS to CO₂ and H₂S, and the subsequent absorption of the H₂S using our market leading PURASPEC™ sulphur removal absorbents.
Our PROTELEC™ getters prevent the build-up of H₂O, hydrogen, carbon dioxide (CO₂) and organic species that are released from enclosed components or the metallised layers of the package.
Olefin purification catalysts
PURASPEC™ absorbents are specially designed to meet the most demanding purity requirements of polymer producers and other users of high purity olefins.
Purification by catalytic oxidation
Our PURAVOC™ technology provides a catalytic oxidation solution to remove a broad variety of volatile organic compounds (VOCs), oxygen, hydrogen and carbon monoxide from various gas stream sources.
Johnson Matthey's fixed bed catalysts technologies are designed to treat water streams effectively, economically and robustly in low input operation.
PURACARE™ tailored service is designed to take care of all aspects of operation, maintenance and absorbent/catalyst recycling for our global customers in the Gas Processing industry.
