摘要： Process for preparing a catalyst composition containing a modified crystalline aluminosilicate and a binder, wherein the catalyst composition comprises from 5 to 95% by weight of crystalline aluminosilicate as based on the total weight of the catalyst composition, the process being remarkable in that it comprises a step of steaming said crystalline aluminosilicate: at a temperature ranging from 100° C. to 380° C.; under a gas phase atmosphere containing from 5 wt % to 100 wt % of steam; at a pressure ranging from 2 to 200 bars; at a partial pressure of H2O ranging from 2 to 200 bars; and said steaming being performed during at least 30 min and up to 144 h; and in that the process also comprises a step of shaping, or of extruding, the crystalline aluminosilicate with a binder, wherein the binder is selected to comprise at least 85 wt % of silica as based on the total weight of the binder, and less than 1000 ppm by weight as based on the total weight of the binder of aluminium, gallium, boron, iron and/or chromium.

摘要： A method which distinctly characterizes and quantifies the pyritic sulfur and the organic sulfur of a sedimentary rock sample. A rock sample is subjected to a heating sequence in an inert atmosphere which produces effluents resulting which are continuously oxidized. SO2 is continuously measured, and a pyrolysis sulfur content and a pyrolysis pyritic sulfur content are deduced therefrom. The residue from heating in an inert atmosphere is then heated in an oxidizing atmosphere. Released SO2 is continuously measured and at least an oxidation sulfur content is deduced therefrom. The pyritic sulfur content is determined from pyrolysis, a weighting function, a second parameter representing the impact of the mineral matrix and a third parameter representing the impact of the organic matrix.

摘要： A method for developing a hydrocarbon reservoir by injecting a gas in the form of foam, comprising a step of determining a foam displacement model, which is a function of an optimal gas mobility reduction factor and of at least one water saturation-dependent interpolation function. The optimal gas mobility reduction factor is determined and constants of the water saturation-related interpolation function are calibrated from a plurality of apparent viscosity measurements for various foam quality values, and by use of a lamella model allowing which relates the lamella density as a function of the water saturation. The invention has an application to petroleum exploration and development.
