Summary of the impact
Globally there are estimated to be 60 million cars produced each year.
These all require catalysts that need testing to meet stringent emissions
legislation. Catagen Ltd, a spin-out from Queen's University has developed
a product for testing motor vehicle catalysts that is 85% cheaper to
operate than traditional methods and represents a 98% reduction
in CO2 emission from testing and an 80%
reduction in energy input.
Major global customers including GM motors and Fiat have adopted this
revolutionary patent protected technology and international sales
growth has been recognised, winning an all- Ireland business award for BEST
High Growth Company 2012
Underpinning research
Engine catalyst research at QUB has been led by Professor Roy Douglas
since the late 1990's. Initial research focused on catalytic converters
for two-stroke engines and addressed the catalytic substrate simply as an
obstruction to the flow of exhaust gas, which hinders the progression of
the main exhausted pulse, and in turn affects the performance of the
engine [1]. This initial research led to a validated catalyst model for
two-stroke applications that involved Douglas and McCullough [2].
A natural progression of the research was to understand the catalysis
processes themselves, research driven by the automotive industry, which
was coming under increasing pressure to reduce and monitor engine
emissions. This work addressed the reaction rates associated with the
storage process, for three-way automotive catalysts [3] and highlighted
the need for precise understanding of the ageing process in catalysts.
Ageing, in this context, refers to the fact that catalysts do not operate
with the same efficiency over long periods (years in terms of required
life-times in cars). Therefore test methods must be able to demonstrate
that new designs will operate effectively (i.e. within engine emission
targets) over sustained periods.
Later work by Douglas and McCullough describes a detailed mathematical
model for oxygen storage, a crucial part of a complete kinetic model of a
three-way automotive catalyst. This model consisted of two interdependent
sub-models with the complex environment of a catalyst: one for the
oxidation process and a second for the reduction process. In this study, O2
and NO were used as oxidizing agents and CO, C3H6
and C3H8 were used as reducing agents [4].
The development of the new dynamic Catalyst Ageing System
for testing motor vehicle catalysts dates back to the formation of
CenTACat in 2003 [6]. CenTACat undertakes multidisciplinary research
involving chemists, physicists and engineers with a common interest in
understanding the fundamental principles that underpin clean energy
production and environmental protection. Within this facility Douglas
supervised PhD student Andrew Woods (now CEO of Catagen) and together they
filed a patent relating to the IP that their research had developed for
testing of catalyst materials [5].

Details of the impact
The data from catalyst aging tests are required in the commercialisation
of any new formulation in the automotive industry. Traditional methods
to achieve this are not only expensive in terms of fuel consumption but
have secondary negative impacts including CO2
emissions. The realisation that exhaust gas recirculation could be
applied to improve such issues was a significant advance and led to the
development of the patented dynamic Catalyst Ageing System. This
technique currently out performs all published ageing procedures
in terms of the balance of overall cost.
It was research into the ageing of catalysts within CenTACat that
resulted in a QUB spinout company Catagen Ltd, which was formed in
May 2011. Catagen produce a range of such ageing systems for the
automotive industry including Labcat. Each system has been
trialled by industry to advance commercialisation of catalytic
technologies. The first system was manufactured by FAST Technologies Ltd
in Derry City with product launch in January 2012. This brought much
needed jobs to a region with the highest youth unemployment in N Ireland.
Catagen will have their own Belfast-based manufacturing facility in 2013,
with FAST involved as a component supplier.
The Catagen technology is regarded as a revolutionary innovation in
laboratory based ageing. The technique which uses the patented dynamic
Catalyst Ageing System costs just over $3 USD per hour to run which
translates to lower running costs than competitors and faster return on
investment. This low carbon technology also outputs 50 times less CO2
compared to engine ageing of equivalent catalyst volumes and space
velocities, therefore representing an environment-friendly
technology. Catagen delivered the first machine to Fiat CRF, Italy
in June 2012 and, at that time, quotations were sent to 6 automotive
companies. Turnover for the year 2012 was £200k and the company is
projecting sales of £1m for 2013, with a company valuation of about £5m at
that time.
In January 2012 Arlene Foster MLA (N Ireland Minster for Trade) described
Catagen as a "Northern Ireland success story" that followed
a great tradition of local manufacturing excellence in the industry. This
is backed up by former Director of Ford Motors in the USA (Rose
Mary Stalker) who stated "The automotive industry is built on innovation
and Labcat is a significant and welcome development ... it
will find international success". Rose Mary Stalker's strong
belief in Catagen resulted in her accepting the position of its Chair in
January 2013.
That international success is now being demonstrated with global sales to
Fiat and General Motors Company (both iconic names and world
leaders in motoring) and a new major deal with Mahle Powertrain, the
second largest company in the world producing engine components. As well
as bringing economic rewards to Catagen this has been acknowledged by the
Best High Growth Company Award at InterTradeIreland's 2012 all-island
Seedcorn Business Competition.
The global market size is estimated at 15,000 test machines (just
within the automotive sector) translating to a required production
capacity of 150 machines per year (current Catagen capacity is 4 machines
per year). Further markets will be coming on-stream, such as small
off-road engines (SORE), which will require catalysts. This will occur
over the next 10 years due to the introduction of new emissions
legislation. Currently 100 million SORE are produced each year.
In summary the technology, developed at QUB, brings economic growth to
the region with global reach in terms of product sales and environmental
impact. Professor Douglas is Chief Technical Officer and shareholder
within Catagen.
