Definitions
- the present invention relates to the field of hydrotreating processes of hydrocarbon feeds operated in the presence of a catalyst comprising composite materials comprising a compound based on at least one crystalline aluminum solid and carbon.
- a hydrotreating catalyst for hydrocarbon cuts is intended to eliminate the sulfur or nitrogen compounds contained therein or to hydrogenate the aromatic molecules, for example to bring a petroleum product to the required specifications (sulfur content, aromatic content, etc.) for a given application (automotive fuel, gasoline or diesel, heating oil, jet fuel). It may also be pretreat this load in order to remove impurities or hydrogenate before subjecting it to various transformation processes to modify the physicochemical properties, such as for example reforming processes, hydrocracking vacuum distillates, catalytic cracking, hydroconversion of atmospheric residues or under vacuum.
- the composition and use of hydrotreatment catalysts are particularly well described in the book Catalysis By Transition Metal Sulfides, From Molecular Theory To Industrial Application by H. Toulhoat and P. Raybaud, published by Technip (2013).
- refractory fillers require catalysts having hydrodesulphurizing and hydrogenating functions which are greatly improved over traditional catalysts.
- conversion processes such as catalytic cracking or hydrocracking use catalysts having an acid function, which makes them particularly sensitive to the presence of nitrogen impurities, including basic nitrogen compounds. It is therefore necessary to use pretreatment catalysts of these fillers so as to remove these compounds.
- Conventional hydrotreatment catalysts generally comprise an oxide-based support (s) and an active phase based on Group VIB and VIII metals.
- the preparation of these catalysts generally comprises a step of impregnating the metals on the support, followed by drying and optionally calcination to obtain the elements in their oxide forms.
- these catalysts are generally subjected to sulphidation in order to form the active phase.
