Microreactors gain interest

This blog has already commented on the attraction of microreactors for greener chemical production, noting recently that one of the winners of the ICIS Innovation Awards - Oxford Catalysts - won it for microreactor developments.  Now market research firm Frost & Sullivan has released a fascinating study into the uptake of this technology.

Oxford Catalysts' microreactor

Says Frost & Sullivan: "The advent of microreactors makes it easier to conduct one-step reactions. Hence, the conventional chemical reactions that produce by-products and waste products can easily be utilized in microreactors to eliminate these alternate reactions, thereby preparing high-quality products.

"Moreover, the fast reaction rates ensure higher yields of up to 100% with high quality and no side reactions. Product quality is enhanced through the accurate control of operation parameters such as pressure, temperature and space velocities."

Oxford Catalysts' raising of a further £21m for future development bodes well for its efforts in biofuels and Fischer-Tropsch reactions in microreactors. Many other players are looking at the technology, which, says the report, has high potential. It points out though that there are risks in implementation:

"The scope for microreactors in fuel and chemical processing is high. However, the non-availability of any commercial demonstration unit that can be retrofitted to an existing facility prevents manufacturers from taking a huge financial risk in their facilities."

Oxford Catalysts raises £21m

As the organiser of the ICIS Innovation Awards each year, it's always rewarding to see winning companies making progress with their innovations. This week, Oxford Catalysts, winner of the SME category in 2009 has raised a further £21m in funding to progress its innovative microreactor technology that can be used to convert biomass and biowaste into syngas ready for conversion into fuels and materials.

The microreactor is very compact

The technology is particularly appropriate as it enables the conversion to be carried out on a local scale, without transport of the biomass. It can also be used to convert stranded fossil fuels such as shale gas.

As the UK startup company says, "with moves towards development of vast shale gas reserves in North America, the increasing focus on the utilisation of stranded and associated gas and the growing interest in biomass-to- liquids (BTL) and waste-to-liquids (WTL) technology, the need to develop distributed technologies such as microchannel processing is more important than ever."  

Microchannel reactors – compact reactors that have channels with diameters in the millimetre range lie at the heart of microchannel processing technology because they intensify chemical reactors, enabling them to occur at rates 10 to 1000 times faster than in conventional systems. 

The Oxford Catalysts Group’s FT technology to produce biofuels has been demonstrated in Güssing, Austria since the summer of 2010 in partnership with SGC Energia, SGPS, S.A. (SGCE). In addition, the Group’s steam methane reforming (SMR) technology is due to be demonstrated in summer 2011 along with the Group’s FT technology in a six barrel per day integrated gas-to-liquids (GTL) pilot plant at a Petrobras refinery in Fortaleza, Brazil. 

The Group received its first order for a commercial scale FT microchannel reactor and highly active FT catalyst in December 2010. It expects that further commercial sales of its microchannel and catalyst technologies to multiple partners will follow in 2011.
