Abstract: Naphthenic acids in crude oil are carboxylic acids characterized by one or more aliphatic or naphthenic rings having an alkyl group with a carboxylic acid group. The naphthenic acids produce atypical corrosion phenomena, given that they can cause a localized attack without the presence of water at 473-693 K, hindering the processing of such crude oils in refineries. Disclosed is a catalytic hydrogenation process that permits selective removal of naphthenic acids from heavy and extra heavy crude oils with a low production of hydrogen sulphides. The catalyst is formed by an aluminium and/or magnesium-aluminium spinel-type support having active Fe—Mo phases. The hydrogenation process using Fe and/or Mo catalysts surprisingly permits an acid number of 1 mg KOH/g to be reached in crude oils with TAN greater than 4 g KOH/g, reducing unwanted reactions and prolonging the life of the cataly

Abstract: An organic/inorganic composite is provided. The organic/inorganic composite comprises a silicon (Si) substrate formed with nanorods or nanoholes and three-dimensional networks of carbon nanotubes (CNTs) grown horizontally in parallel and suspended between the adjacent nanorods or inside the nanoholes. In the organic/inorganic composite, metal catalysts can be uniformly formed on the nanorods or inside the nanoholes, irrespective of the height of the nanorods or the depth of the nanoholes and the shape and aspect ratio of the nanorods or nanoholes. In addition, the carbon nanotubes grow in a three-dimensional network structure directly over the entire surface of the nanorods or the whole inner surface of the nanoholes and are directly connected to the base electrodes. With this configuration, the three-dimensional carbon nanotube networks are highly dense per unit volume, and the organic/inorganic composite is highly electrically conductive and has a large surface area. Therefore, the use of the organic/inorganic composite enables the fabrication of an electronic device with greatly improved efficiency. Further provided are a method for preparing the organic/inorganic composite and an electronic device fabricated using the organic/inorganic composite.
