Due to the large number of posts recently, there is currently a delay of several weeks between posts being submitted and the corresponding emails being distributed to all users. Please bear with us while we try to improve this. In the meantime – and until this notice is removed – it would assist us considerably if you could submit only important and/or urgent posts and thus help to reduce the size of the mail queue. Under no circumstances should you resend posts multiple times when you find the emails are not distributed immediately.
In light of the Russian military offensive in Ukraine, we request that announcements relating to events, jobs and other activities associated with institutions supported by the Russian and Belarusian states are not posted to the Psi-k forum.

Title: Ab initio microkinetic modelling of hydrodesulfurization reactions catalysed by transition metal sulfides
One post-doctoral position (1 year, renewable for 6 months) will be opened from September 2016 in the Catalysis and Separation Division of IFP New Energy under the supervision of Pascal Raybaud.
Abstract
The atomic scale elucidation of catalytic hydrodesulfurization mechanisms is a mandatory step to open new routes for the improvement of transition metal sulfides catalysts industrially used.[1] However, bridging the gap between this atomic scale understanding and the industrial process requires to establish robust microkinetic models based on reaction rates calculated at a quantum level. A set of calculated adsorption constants of complex hydrocarbon molecules on a multisite model of MoS2 based active phases have been recently determined by some of us.[2] The present post-doctoral research project aims at solving reaction mechanisms involving the carbon-sulfur bond breaking of such complex hydrocarbon molecules. In a second step, a microkinetic model will be built in order to simulate activity, selectivity and inhibiting effects. The theoretical results will be compared with available experimental catalytic data.
