Abstract: The present invention deals with activation and start-up procedures of catalysts for the deep HDS of middle distillates for producing ultra low sulfur diesel (ULSD), consisting of two in situ activation stages: at stage 1, TGA is applied, and at stage 2, DMDS is used; kerosene is the transport means at these stages, which are carried out under given temperature and pressure conditions, and feedstock and hydrogen flows at established times. After the activation of the catalyst in situ, the stabilization stage takes place under selected temperature and pressure conditions, feedstock and hydrogen flow at established times, with which the stabilization of the highly dispersed metallic sulfides is achieved and, in this way, the activity of the catalysts removing contaminants for the production of ULSD is increased.

Abstract: The invention concerns a process for the continuous treatment of an emulsion and/or a micro-emulsion assisted by an “expanded liquid” for the production of micro- and/or nano-particles or micro- and/or nano-spheres containing one or more active ingredients. In particular, a liquid solvent expanded by compressed or supercritical CO2 is contacted with an O/W emulsion, or alternatively a W/O emulsion or multiple emulsions, formed by an external phase that is itself a liquid expanded by compressed CO2. The expanded liquid forms a solution with the dispersed phase of the emulsion and extracts it inducing the formation of the desired particles of the dissolved compounds.The process is carried out in a counter-current packed column wherein the expanded emulsion is fed from the top, while the expanded liquid is fed from the bottom. Thanks to the presence of the expanded liquid, any deposition of the solid particles produced on the packing elements is avoided, thus preventing any column blockage. A suspension of micro-structured particles of the desired product can be collected continuously at the bottom of the column.

Abstract: The present invention describes a process for quenching a hydrothermal, dilute acid hydrolysis reaction of a biomass feedstock, wherein degradation of an aqueous monomer and/or oligomer sugar mixture is slowed down or stopped by flash cooling of the aqueous monomer and/or oligomer sugar mixture, and wherein the flash cooling ensures that a fraction of dissolved and volatile degradation byproducts are removed by a forming vapor stream, and wherein a lignin component, if present, is solidified into a structure with good de-watering characteristics, allowing for subsequent removal of the lignin component by separation, said process resulting in a hydrolyzed solution of sugar monomers and/or oligomers.
