摘要: The present invention relates to a process for deparaffinning a middle distillate feedstock, to convert, in good yield, feedstocks having high pour points into at least one cut having an improved pour point.
Said process is performed with at least one catalyst comprising at least one hydro-dehydrogenating phase containing at least one metal from group VIB and at least one metal from group VIII of the Periodic Table of the Elements, and a support comprising at least one IZM-2 zeolite, a zeolite of WI framework type code and at least one binder.-

摘要: Process for preparing alumina gel in a single precipitation step consisting of dissolving an aluminium precursor, aluminium chloride, in water, at a temperature of 10° C. to 90° C. such that the pH of the solution is from 0.5 to 5, for a period of 2 to 60 minutes, then adjusting the pH to 7.5 to 9.5 by adding a basic precursor, sodium hydroxide, to the solution obtained to obtain a suspension, at a temperature of 5° C. to 35° C., and for 5 minutes to 5 hours, followed by a filtration step, said process not comprising any washing steps. Also, novel alumina gel having a high dispersibility index, in particular a dispersibility index of more than 80%, a crystallite dimension of 0.5 to 10 nm, a chlorine content of 0.001% to 2% by weight and a sodium content of 0.001% to 2% by weight, the percentages by weight being expressed with respect to the total weight of the alumina gel.

摘要: A process for producing cellulolytic and/or hemicellulolytic enzymes with a strain of microorganism belonging to the family of filamentous fungi. The process includes growing the fungi in an aqueous culture medium, in the presence of at least one carbon-based growth substrate, in a stirred and aerated bioreactor. It also includes the production of enzymes, starting with the aqueous culture medium in the presence of at least one inductive carbon-based substrate and also inducing the production of hydrophobins. Further, at least a portion of the hydrophobins produced in step (b) are reintroduced into the growth step (a).

摘要: The present invention relates to an electric propulsion system (1) for a rolling object, comprising a frame (2) with at least one motorized wheel (3), and at least one non-motorized wheel (4), a handlebar (6) and coupling means (5). Coupling means (5) are intended for gripping, orientation and lifting of at least one wheel of the rolling load. The means of orienting the wheel of the rolling object orient the wheel perpendicular to the longitudinal direction (x) of the frame.

摘要: A distributor tray (100) for a column for contact between a gas (G) and a liquid (L) is provided wherein the distributor tray has a plurality of compartments defined on one face of the tray by secant partitions (104) which are perforated (105) to allow the flow of liquid between adjacent compartments. Each compartment includes at least one passage of the liquid through the tray or a chimney (102) projecting from the tray for the exclusive passage of the gas (G) through the tray. The shape of the chimney is identical to the shape of the compartment containing it, and the chimney has an internal volume at least equal to the volume of the compartment containing it.
