Abstract: The present disclosure describes hybrid binary catalysts (HBCs) that can be used as engine aftertreatment catalyst compositions, specifically 4-way catalyst compositions. The HBCs provide solutions to the challenges facing emissions control. In general, the HBCs include a porous primary catalyst and a secondary catalyst. The secondary catalyst partial coats the surfaces (e.g., the internal porous surface and/or the external surface) of the primary catalyst resulting in a hybridized composition. The synthesis of the HBCs can provide a primary catalyst whose entire surface, or portions thereof, can be coated with the secondary catalyst.

Abstract: The invention relates to the integration of a process for hydrotreatment of distillates (light and/or middle), that operates under a hydrogen partial pressure of 0.5 to 6.0 MPa, with a process for hydrotreatment/hydroconversion of middle and/or heavy distillates that operates at a hydrogen partial pressure that is at least 4.0 MPa higher than the hydrogen partial pressure of the process for hydrotreatment of distillates (light and/or middle). The integration resides in the use of the hydrogen-rich gas, obtained from the hydrotreatment/hydroconversion effluents, in the process for hydrotreatment of distillates (light and/or middle) and in the adjustment of the pressure level of this hydrogen-rich gas removed from the hydrotreatment/hydroconversion. This invention makes it possible to considerably reduce the net consumption of make-up hydrogen in the process for hydrotreatment of distillates (light and/or middle).
