Fuel Composition

Compositions and methods for forming hydrocarbon products from triglycerides are disclosed. In one aspect, the methods involve the thermal decomposition of fatty acids, which can be derived from the hydrolysis of triglycerides. The thermal decomposition products can be combined with low molecular weight olefins, such as Fischer-Tropsch synthesis products, and subjected to molecular averaging reactions. Alternatively, the products can be subjected to hydrocracking reactions, isomerization reactions, and the like. The products can be isolated in the gasoline, jet and / or diesel fuel ranges. Thus, vegetable oils and / or animal fats can be converted using water, catalysts, and heat, into conventional products in the gasoline, jet and / or diesel fuel ranges. These products are virtually indistinguishable from those derived from their petroleum-based analogs, except that they can have virtually no aromatic, sulfur or nitrogen content, they are derived, in whole or in part, from renewable resources, and can also be derived from domestically available coal and / or natural gas.

Method for obtaining ozonized oils and vegetable fats and use of said products for pharmaceutical and cosmetic purposes

This invention is linked to the chemical, pharmaceutical and cosmetic industries, where the bactericidal, virucidal, parasiticidal and fungicidal properties of the ozonized vegetable oils and fats are considered. The emulsified vegetable oil or fat is driven to react with ozone in a bubbling reactor, covered by a jacket that makes possible to control the reaction's temperature. Ozone reacts with the double bonds present in vegetable oil or fat, giving rise to the formation of different peroxidic species, responsible for the biological action of those products. The ozonized vegetable oils and fats in those conditions are applied with satisfactory and advanced results to the treatment of diseases in diverse medical specialties, such as ophthalmology, dentistry, dermatology, gastroenterology, gynecology, parasitology, and others. Likewise, the cosmetic application of the ozonized vegetable oil and fats is described, considering their oxygenating and revitalizing properties of the skin. The results of the toxicological studies previously performed show that the products obtained according to this process do not show any cross or adverse reaction.
