  • Method for Producing Synthentic Alkyl Aromatic Lubricant Oil for Refrigeration Compressors by Selection of Solid Acid Catalysts Modified During the Integrated Alkylation and Transalkylation Process in Reactive Distillation Columns
    Publication number: 20160347683
    Abstract: The present invention refers to a process of obtaining alkylaromatic compounds where there is a higher selectivity for the production of monoalkylaromatic compounds by selection of modified acid solid catalysts in an integrated process comprising an alkylation and transalkylation of aromatic and/or polyaromatic compounds for the selective production of monoalkylaromatic compounds, as well as regeneration (in situ) of acid solid catalysts selected for this process. The process of the present invention enables the achievement of monoalkylated compounds with high rates of conversion, selectivity and yield.

  • Oil, Lubricant Composition Having Improved Lubricity and Increased Coefficient of Performance, Uses and Mechanical Equipment
    Publication number: 20160319214
    Abstract: The present invention discloses an oil including at least one alkyl aromatic compound wherein the oil viscosity is lower than 3.0 cSt at the temperature of 40° C. The oil of the present invention shows a lower viscosity variation as a function of the temperature, what contributes to reduce the cooling system equipment wear and increase the equipment operation lifetime, for example, the operation lifetime of the cooling compressors. It also an object of the present invention a composition including said oil in combination with at least one fluid of the hydrocarbon (HC) type and its uses in mechanical equipments and mechanical equipments made with said oil and/or composition.
