  • Patent number: 12312542
    Abstract: The present invention relates to a method for reducing deactivation of a hydrotreatment catalyst. The hydrotreatment catalyst is used as a main active catalyst for producing renewable hydrocarbons by hydrotreatment from a renewable feedstock which comprises at least an oxygen containing compound, at least one metal containing compound and at least one phosphorus containing compound as impurities. The method comprising adjusting the metal to phosphorus (M:P) weight ratio of the renewable feedstock to a value within the range from 0.70 to 1.26, measured as elemental metal and elemental phosphorus, subjecting the obtained feedstock to a temperature of from 190 to 400° C. under reducing conditions, thereby forming a solid precipitate comprising at least one metal and phosphorus containing compound, and contacting the obtained liquid renewable feedstock with the main active catalyst, in the presence of hydrogen.

  • Patent number: 12187965
    Abstract: The present disclosure provides a versatile process for producing valuable renewable hydrocarbons from triglyceride containing feedstock. The triglyceride containing feedstock is first split to provide a mixture containing fatty acids, glycerol and water, from which a phase separation provides an oily phase, and an aqueous phase. The oily phase containing fatty acids is subjected to fractionation, whereby specific fractions may be refined to products with controlled hydroprocessing. Products may contain paraffinic renewable aviation fuel components, paraffinic renewable base oil, renewable paraffinic diesel fuel components, renewable paraffinic technical fluid, or any combination thereof.
