Abstract: A method for automatic configuration and use of Category 1 message filtering rules includes, at a network function (NF), subscribing, with an NF repository function (NRF), to receive notification of NF profile changes. The method further includes receiving, from the NRF and as a result of the subscribing, notification of an NF profile change. The method further includes automatically configuring, based on the notification of the NF profile change, at least one Category 1 message filtering rule implemented. The method further includes using the at least one Category 1 message filtering rule to filter service based interface (SBI) messages.

Abstract: A catalyst for hydrotreating, especially hydrodesulfurization, of residua and heavy crudes is prepared by synthesizing the support from titanium and boehmite, to form either a titanium/alumina support (TiO2/Al2O3) or a titanium-alumina support (TiO2—Al2O3) that is thereafter provided with at least one hydrogenating metal from group VIB in oxide form and a promoter from group VIII also in oxide form. The (TiO2/Al2O3) support is prepared from boehmite, which is peptized by using an inorganic acid, then extruded, calcined and impregnated with a solution containing titanium, while the (TiO2—Al2O3) support is prepared by admixing boehmite with a titanium-containing solution, peptized using an inorganic acid, extruded and calcined to obtain the titanium-alumina support.
