Technology

Development of advanced chemical process technology is a significant part of Matros Tech's operation. The tradition of innovation is rooted in academic research our associates have been involved with before forming Matros Technologies. The company’s members authored tens of patents and numerous scientific and technical publications.

For a number of novel catalytic processes we propose a revolutionary approach based on a forced unsteady-state operation of chemical reactors – an area where Matros Technologies is a recognized world leader. Our founder and President, Dr. Yurii Matros, is an inventor of a reversed-flow reactor technology (Matros reactor) widely applied for control of air pollution by sulfur dioxide, volatile organic compounds and nitrogen oxides.

Below is the list of catalytic processes invented by the MT associates either used commercially or tested on pilot scale:

    • SO2 Oxidation to SO3 for sulfuric acid production. The process concept was conceived by Dr. Matros in mid 70-s. After much controversy surrounding initial development stages, a pilot plant has been successfully started up in 1979. In 1982, the first commercial unit treating 40,000 Nm3/hr of copper smelter gas has been built in Krasnouralsk, Russia. During the 80s and 90s, the technology and its inventor have received world recognition. That resulted in numerous plants having been built worldwide. The most recent, largest plant has been started up in 2000 at Port Kembla Copper Ltd. Plant in Australia, as a result of MT’s cooperation with Hitachi Zosen Corp. (Osaka, Japan).

    • Regenerative Catalytic Oxidizer (RCO) technology for VOC oxidation from industrial sources. First plants using Matros’ RCO technology have been built in former Soviet Union in the 80s. The technology was licensed by Monsanto Enviro-Chem who commercialized it worldwide. Ongoing innovation resulted in such developments as

    • - purge system to achieve destruction efficiency in excess of 99 %,

      - RTO retrofitting technology allowing drastic reduction in energy use,

      - in-situ regeneration of poisoned VOC oxidation catalyst,

      - oxidation of nitrogen-containing VOCs with extremely low NOx production,

      - combination of RCO with an air stripper for VOC removal from wastewater.

    • Selective Catalytic Reduction (SCR) technology for NOx removal in a reversed-flow reactor. A commercial plant using this technology has been in operation since 1989.

    • Conversion of methanol to formaldehyde on oxide catalysts using adiabatic catalyst beds. The technology was implemented in a number of plants, both as an upgrade of multitubular reactors and in a unique plant comprising only adiabatic catalyst beds.

    • A technology for direct catalytic oxidation of sulfurous compounds (H2S, CS2, etc.) into SO3 that allows recovery of waste gases (such as from viscose production plants) as sulfuric acid.

    • A Reversed Flow Converter (RFC) for automotive exhaust aftertreatment. The technology is being developed in cooperation with Alternative Fuel Systems, Inc. (Calgary, Canada). An initial version, developed for methane destruction after diesel dual-fuel engines, is currently undergoing road tests. The next generation – four-way converter (removal of hydrocarbons, CO, NOx and particulates) for diesel application – is being developed.

    • Catalytic combustion of low-grade fuels and waste gases in reversed-flow reactor for energy generation.

    • Processes for ammonia and methanol syntheses in a reversed-flow reactors have been successfully pilot tested.

In 2001, Matros Technologies, Inc. filed a patent application for a simple, compact and energy efficient fuel processor that converts hydrocarbons and other organic compounds into either hydrogen or synthesis gas, depending on configuration. It is based upon the reversed-flow reactor concept, being investigated by Dr. Matros’ group since early 80s. The novel solution provides for improved operating parameters and allows for seamless integration of partial oxidation of the feedstock with water-gas shift catalyst bed.

Matros fuel processor technology is available for licensing and/or joint development.

The results of MT’s process development results have been documented in numerous publications and protected by patents worldwide.
