摘要： The present invention is directed to a nanostructured binary oxide TiO2—Al2O3 with high acidity and its synthesis process via the sol-gel method, hydrotreating and thermal activation. The nanostructured binary oxide TiO2—Al2O3 with high acidity consists basically of titanium oxide and aluminum oxide with the special characteristic of being obtained as nanostructures, in their nanocrystal-nanotube evolution, which provides special physicochemical properties such as high specific area, purity and phase stability, acidity stability and different types of active acid sites, in addition to the capacity to disperse and stabilize active metal particles with high activity and selectivity mainly in catalytic processes.

摘要： Compounds and compositions are used as corrosion inhibitors for pipelines for crude oil containing water with high salt concentrations. The inhibitors are ionic liquids, imidazoles, benzotriazoles, and mixtures thereof. The composition includes two or more members of the inhibitors with a solvent. The inhibitors reduce corrosion of metallic surfaces of the pipelines containing crude oil having 0.2 and 40 wt % water, 10,000 to 70,000 ppm salt, and 9 to 600 ppm hydrogen sulfide. A synergic effect is provided by two or more different inhibitors. This synergy is derived from interactions with the metallic surface, among themselves or with the corrosive medium depending on the chain length, to inhibit the corrosion with decrease of the formulation dose. The composition can be a ternary formulation of the three families or two components of one family and a third component of a different family.
