Abstract: The present invention relates to a process of obtainment of aviation biokerosene and a composition of aviation kerosene containing the aviation biokerosene thus produced. The process consists of simultaneously combining three basic conditions: raw material selection, processing conditions, and control of specific properties of the product. The composition is classified as a semisynthetic composition of aviation kerosene and may contain up to 20% by weight of aviation biokerosene, satisfying the limits determined in the international specifications for aviation kerosene.

Abstract: An aviation gasoline (Avgas) formulation free from tetraethyl lead (TEL) for piston driven aircraft is described, the formulation comprising, in volume percent, between 0 and 65.2 base alkylate, between 0 and 50 super-alkylate, between 0 and 25 toluene, between 2 and 10 of a toluidine isomer blend, between 0 and 5 ethyl alcohol, between 0 and 25 C5 cut and between 0 and 10 triptane. The formulations are prepared by admixing the components, with the order of mixing being from the denser to the less dense, except in the case of the toluidine isomer blend, which in spite of being the denser product is the latest to be added to the other streams in order to by-pass homogenization problems.

Abstract: A modular system used to visually inspect the interior of storage tanks and to simultaneously collect samples to analyze the products stored. The modular internal inspection system includes an assembly made up by a pneumatic controller (2), a pneumatic module (3), an interface module (4), a control module (5), an operation module (6), and several connection cables (7a, 7b, 7c). The system may be remotely operated and allows recording the images and the data collected during inspection. The modular internal tank inspection system is used in storage tanks (1) of any geometric configuration, normally found in industrial installations. Furthermore, because it is an intrinsically secure system, it may be used on tanks that store different types of liquid fuels, with no risk of explosion.
