Abstract: Aspects include a robotic device for inspection of components of a belt conveyor comprising a mobile platform and a robotic arm having a first end coupled to the mobile platform and a second end, the robotic arm configured to guide the second end to contact at least one of the components of the belt conveyor. Further included is a method for inspecting components of a belt conveyor using a robotic device, including: obtaining temperature and/or noise data of at least one of the components of the belt conveyor; and, if the data are outside a range, then: driving a second end a robotic arm of the robotic device for contacting at least one of the components; and obtaining vibration data from at least one of the components.

Abstract: The present invention relates to a process for producing esters comprising reaction of methyl biodiesel or free fatty acids with a polyhydroxylated alcohol, in the presence of a biocatalyst, which is a fermented solid containing lipases of Rhizomucor miehei produced by culturing the microorganism on agricultural waste by solid state fermentation.

Abstract: The present invention is related to technologies used to inspect flexible undersea pipes, in particular to detect flooding of the annular space in said pipes. The present invention discloses a device for detecting annular flooding with gamma transmission in a flexible pipe, comprising a structure (07), in which said structure (07) contains in its interior, a first pressure vessel (10) containing an encapsulated radioactive source (03) in its interior, a second pressure vessel (11) containing radiation sensors (04) in its interior, and a third pressure vessel (12), containing electronic means for collecting and amplifying signals (05) in its interior, in which said radiation sensors (04) are connected to the electronic means (05) for collecting and amplifying signals using an internal cable (13).

Abstract: The invention relates to the preparation of carboxylic acid esters compounds, biodiesel (B) from microalgae, for use as a biofuel for compression type ignition. The objective is achieved through a hydroesterification process of a microalgae biomass (MU) comprising a hydrolysis stage and the esterification stage by means of heterogeneous catalysis. The wet microalgae biomass (MU) is the result of a process of cultivation concentration and is hydrolyzed directly in a hydrolysis column (20). Fatty acids (C), water (A) and raw glycerin (G) are obtained following the hydrolysis. The fatty acids (C) are esterified by reactive distillation in the presence of an impregnated heterogeneous catalyst (I).

Abstract: The present invention relates to a process of formulating and preparing supported multi-metal catalysts based on metal oxides and inorganic salts of metals. The impregnation technique is employed by two methods: the slurry method and the modified-pH variation method, which are used in two steps for obtaining the catalyst. The present invention also relates to a process called Glycerol to Propene (GTP) process, corresponding to the transformation of glycerol or glycerin to propene. The reaction involved in the process of the present invention is the selective hydrogenation of glycerin, which takes place by contact of the charge of glycerin carried by hydrogen in a continuous stream system on the catalytic bed containing multi-metal catalysts, specifically prepared for this purpose.
