    • A process for reducing the naphthenic acidity of petroleum oils or their fractions is described, said process comprising providing a hydrocarbon feed 103/203/303 having between 0.1 and 99 wt % of emulsified/dispersed water in oil, said feed containing salts and a content of naphthenic acids measured as TAN between 0.1 and 10 mg KOH/g oil; directing the said petroleum oil feed and emulsified/dispersed water towards an energy emitter device in the microwave range and submitting said feed 103/203/303 in liquid phase, under pressure between 0.7 and 4.5 MPa at temperatures between 50° C. and 350° C. to the microwave radiation, applied in the range of 1 mm to 30 cm to said feed so that the presence of salts, the applied temperature and the high dielectric constant of the water droplets make that the heat is absorbed on the spot by the water and heat said water preferentially to the oil, while the naphthenic compounds at the interface between the droplets and the oil catch said heat; effecting the decomposition of the carboxylic acids responsible for the naphthenic acidity in the petroleum feed at temperatures around 320° C. and generating CO2; separating with the aid of any known device 106/106′/112/117/208/208′/214/219/310/310′/316/321 any gas phase generated, water and oil; and recovering the hydrocarbon oil stream 108/113/119/210/215/221/312/317/323 having a reduced content in naphthenic acids. The process is designed to be applied to the reduction of naphthenic acids in feeds of petroleum oils and their fractions in the oil production step, in refineries or any industrial installation.
    • 描述了降低石油或其馏分的环烷酸性的方法，所述方法包括提供具有0.1至99重量％的乳化/分散水在油中的所述烃进料103/203/303，所述进料含有盐和含量 以0.1至10mg KOH / g油测量的TAN的环烷酸; 将所述石油进料和乳化/分散的水引导到微波范围内的能量发射器装置，并将液体相中的所述进料103/203/303在压力为0.7-4.5MPa之间的温度下在50℃和350℃之间 C.到微波辐射，施加在所述进料的1mm至30cm的范围内，使得盐的存在，施加的温度和水滴的高介电常数使得热量被现场吸收 水和热将水优先转化为油，而在液滴和油之间的界面处的环烷烃化合物捕获所述热量; 在约320℃的温度下，在石油进料中引起负责环烷酸性的羧酸的分解并产生CO 2; 借助任何已知装置106/106'/ 214/219/310/310'/ 316/321进行分离，产生任何气相，水和油; 并回收具有降低的环烷酸含量的烃油流108/113/119/210/215/221/312/317/323。 该方法设计用于在石油生产步骤，炼油厂或任何工业装置中降低石油及其馏分的进料中的环烷酸。

    • The present invention comprises a thermo catalytic process to produce diesel oil from vegetal oils, in refineries which have two or more Catalytic Cracking (FCC) reactors. At least one reactor processes heavy gasoleum or residue in conventional operation conditions while at least one reactor processes vegetal oils in proper operation conditions to produce diesel oil. This process employs the same catalyst employed in the FCC process, which processes conventional feedstocks simultaneously. This process transforms high heat content raw materials into fuel hydrocarbons. It shows excellent efficiency for the obtention of highly pure products and do not yield glycerin, one by-product of the transesterification process. The diesel oil produced by said process presents quality superior and cetane number higher than 40. Once cracking reactions occur at lower temperatures, it forms less oxidized product, which is consequently purer than those obtained by existent technology are.
    • 本发明包括在具有两个或更多个催化裂化（FCC）反应器的炼油厂中从植物油生产柴油的热催化方法。 至少一个反应器在常规操作条件下处理重型气体或残留物，而至少一个反应器在合适的操作条件下处理植物油以产生柴油。 该方法采用与FCC方法相同的催化剂，其同时处理常规原料。 该过程将高热原料转化为燃料碳氢化合物。 对于获得高纯度产品而言，显示出优异的效率，并且不产生作为酯交换方法的副产物的甘油。 所述方法生产的柴油质量优良，十六烷值高于40℃。一旦在较低温度下发生裂解反应，其形成的氧化产物较少，因此比现有技术获得的产物更纯净。
