Chiyoda Licenses Titania Catalyst for Ultra Deep Hydrodesulfurization of Diesel Oil to a French Company Axens



    Chiyoda Corporation (TOKYO:6366; ISIN: JP3528600004), Japan's
    leading engineering and construction firm, today announces that it is
    licensing titania catalyst for ultra deep hydrodesulfurization (HDS)
    of diesel oil to Axens, a French subsidiary of IFP. Chiyoda is aiming
    to supply the catalyst for diesel oil in order to meet sulfur content
    regulation which will be reinforced globally in years to come.

    Chiyoda joined a research project sponsored by the "New Energy and
    Industrial Technology Development Organization "(NEDO), & "Japan
    Petroleum Energy Center" (JPEC), and has investigated titania catalyst
    for ultra deep hydrodesulfurization of diesel oil. The activity of
    titania catalyst per unit surface area has been known to be more
    active than that of alumina catalyst which is normally used for
    hydrodesulfurization of diesel oil; however, technical difficulty to
    prepare the titania catalyst with large surface area has prevented its
    commercial application. Chiyoda has come up with its proprietary
    method to overcome this difficulty.

    Axens, headed by Mr. Jean Sentenac, is a global company with
    activities that include process licensing in the fields of refinery
    and petrochemical industries, and manufacture and sales of various
    catalysts used in those fields. Axens is a leading process licensor in
    the hydrodesulfurization of gasoline and diesel oils, and supplies the
    catalysts for such processes and is highly-evaluated internationally.

    The titania catalyst, which has been jointly developed by Axens
    and Chiyoda, has very high activity for hydrodesulfurization and it
    allows oil companies to produce sulfur-free diesel under the reaction
    condition in which the temperature is around 10-20 degrees Celsius
    lower than that with conventional alumina catalyst. Also, it is worth
    mentioning that it has strong interaction with nitrogen-contained
    aromatic compound and accordingly has higher hydrodenitogenation (HDN)
    selectivity than that of alumina catalyst. It is estimated that this
    characteristic may allow its expanded use to hydrotreatment of various
    distillates with higher nitrogen content in future.

    Axens is currently working on the final adjustment of industrial
    operating parameters and has scheduled the production of first
    commercial batches of titania precursor and hydrotreatment catalyst in
    the first quarter of 2008.

    In Japan sulfur-free regulation (less than 10 ppm) has been
    started from 2007. Two years ahead the implementation of the
    regulation most oil companies in Japan had already started to supply
    sulfur-free diesel from 2005. In collaboration with Axens and Chiyoda,
    it is intended to supply commercialized product globally starting from
    Europe, where sulfur-free regulation starts in 2009.

    Chiyoda Corporation, headquartered in Yokohama, Japan, provides
    services in the field of engineering, procurement and construction
    (EPC) for gas processing, oil refineries and other hydrocarbon
    processing and industrial plant projects, particularly in Gas Value
    Chain areas, on a global basis including the Middle East, Russia,
    Africa and South East Asian regions. For almost 60 years, Chiyoda has
    constantly leveraged its extensive experience and a far-reaching
    global network to give it an unrivaled advantage.
