Patent number: 11898189Abstract: A microalgal strain of the species Nannochloropsis gaditana is characterized by a mutation of an enzyme involved in the biosynthesis of chlorophyll that changes the physiology thereof with respect to the wild-type strain of the same species. In particular, with the mutation, microalgae are formed which, with respect to the wild-type strain of the same species, have a lower chlorophyll content and a reduced capacity to absorb visible radiation (light). Further, a process for the production of lipids through the cultivation of the mutated Nannochloropsis gaditana strain and the lipids obtained can be used as synthesis intermediates, particularly in the so-called “green-chemistry” sector or in the production of biofuels.Type: GrantFiled: December 5, 2019Date of Patent: February 13, 2024Assignee: ENI S.P.A.Inventors: Roberta Miglio, Tomas Morosinotto, Alessandra Bellan

Patent number: 11884565Abstract: There is a process for the production of a liquid fuel and of a gaseous fuel from biomass. The biomass is sent to a pre-treatment section to form a homogeneous phase that can be moved and/or pumped, wherein inert parts are separated from the biomass and the biomass shredded and/or ground to reduce its size. The homogeneous phase obtained is then subjected to subcritical hydrothermal liquefaction at a temperature between 240° C. and 310° C. to form a liquefied phase. The liquefied phase is separated. After separation, the process continues in two alternative and mutually exclusive modes. In the first mode, the first aqueous phase is subjected to an anaerobic reaction with multiple stages producing biogas; the oily phase is separated into a bio-oil and a solid residue. In the second mode, the separate mixed phase is separated by density or dynamics forming a first aqueous phase, bio-oil and a gaseous phase.Type: GrantFiled: July 31, 2019Date of Patent: January 30, 2024Assignee: ENI S.P.A.Inventors: Roberta Miglio, Roberto Paglino, Cristian Torri, Alisar Kiwan, Daniele Fabbri
