Résumé

A French University has set up two methods to eliminate selectively Hydrodesulfurization (HDS) inhibitors. Hydrodesulfurization (HDS) is a catalytic chemical process widely used to remove sulfur from diesel fuel. Despite the tremendous improvement of the catalysts activity, the inhibiting effect on HDS of trace polar compounds and among them nitrogen compounds has received much attention. Industrial partners are sought for license agreements or R&D co-operation.

Description complète

European emission standards force oil refineries to dramatically reduce the level of sulfur in diesel fuel down to 10ppm. Deep desulfurization processes of diesel fuel range are inhibited by trace polar elements and among them nitrogen compounds. Their elimination is necessary to increase dramatically the efficiency of hydrotreatment process. Furthermore, trace polar compounds found in petroleum distillates can affect the stability of the fuel and can act as pro-oxides causing fouling and gum formation. The selective removal of these hydrodesulfurization inhibitors improves catalysts lifespan and enables the decrease of HDS temperature. Two patented technologies are available: continuous process via liquid-liquid extraction using RTILs and fixed-bed technology using commercially available polymers.

Aspects innovants

- Selective extraction of HDS inhibitors and among them neutral nitrogen compounds
- High selectivity towards other components of the Diesel feed
- Continuous process or fixed-bed technology

Expertise recherchée:

- Type of partner sought: Industrial Partners
- Specific area of activity of the partner: Oil industry & Oil refinery
- Task to be performed by the partner sought: industrialisation of the process
