Abstract: A hybrid reinforcing fabric includes glass fibers and carbon fibers. The hybrid reinforcing fabric can be readily infused at an acceptable infusion speed, without requiring that the carbon fiber tows used resin. Thus, the fabric provides for an effective one-step (i.e., in the mold) infusion process during composite part formation.

Abstract: The present invention relates to an original process for the preparation of a catalyst in the form of an extrudate comprising an acid zeolite with the structural code MFI, the zeolite content being between 45% and 90% relative to the total mass of the catalyst, and a binder, and optionally containing a hydrogenating active phase, comprising at least a) the mixture of said MFI zeolite and the binder, the average size of the elementary particles of said MFI zeolite being between 110 and 800 nm, b) the addition of said mixture a) of a peptizing agent c) the addition to said mixture of a neutralizing agent d) the shaping by extrusion of the mixture e) optionally, the drying of the solid, f) the heat treatment of the said solid obtained in the presence of water vapor at a temperature between 400 and 1000° C. in the presence of an air flow containing from 1 to 60% by volume of water, and g) optionally, the introduction of one or more precursors of a hydrogenating active phase on the solid.

Abstract: Fabrics formed from a multitude of continuous fibers, each of the fibers including many individual filaments, are disclosed. The fibers are held together by a stitching yarn. Properties of the stitching yarn allow a resin to more readily flow through the fabric.

Abstract: 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.

Abstract: A process for preparing a powder support containing alumina and silica or their derivatives for a catalyst of a Fischer-Tropsch type reaction, including stage (a) of preparing a first reactant containing an alumina compound or precursor including a reaction for peptization of an alumina compound or precursor in the presence of an acid, to form solid particles in suspension, stage (b) of preparing a second reactant based on silicic acid and/or on a compound or precursor of silicic acid, including a controlled aging treatment of the silicic acid targeted at its polymerization up to a degree of conversion of the silicic acid of at most 70%, stage (c) of mixing the two reactants in a mixer, and the pH of the first reactant is adjusted to a value not exceeding a given maximum pH threshold.

Abstract: A hybrid reinforcing fabric includes glass fibers and carbon fibers. The hybrid reinforcing fabric can be readily infused at an acceptable infusion speed, without requiring that the carbon fiber tows used to form the hybrid reinforcement fabric be spread or pre-impregnated with resin. Thus, the fabric provides for an effective one-step (i.e., in the mold) infusion process during composite part formation.
