BOPI 04 BR/2024 REPERTOIRE NUMERIQUE 36 production. The process is highlighted via the effective and successful scale up of a purification process for the removal of a variety of different classes of impurities from crude vegetable oils mixtures into feedstocks that can be directly integrated into the hydrotreatment vegetable oil hydrogénation process for mass production of synthetic diesel derived from renewable sources.

(72) MARTI Patrik (CH) (73) VICAT, 4 rue Aristide Bergès, Les Trois Vallons, 38080 L'ISLE D'ABEAU (FR) (74) SCP Cabinet NGO MINYOGOG & ASSOCIES, Sis derrière Immeuble ancien FONADER, B.P. 20501, YAOUNDE (CM). (57) The three-dimensional printing head comprises a dynamic mixer (3) comprising a mixer casing (4), which delimits a mixing chamber (5), a supply inlet (15) configured to supply the mixing chamber (5) with a mineral composition and a discharge outlet (16); and an injector (19) for injecting a building material admixture in the mixing chamber (5). The injector (19) includes a tubular injecting member (25) being flexible and having an injection outlet (26), the tubular injecting member (25) being elastically deformable between a first state in which the tubular injecting member (25) is configured to allow a flow of the building material admixture through the tubular injecting member (25) and towards the injection outlet (26), and a second state in which thé tubular injecting member (25) is configured to prevent a flow of the mineral composition from the mixing chamber (5) and through the tubular injecting member (25).
