Title: Alessandra Rangel Cassella: Innovator in Oil and Biomass Technologies
Introduction
Alessandra Rangel Cassella is a prominent inventor based in Rio de Janeiro, Brazil. She has made significant contributions to the fields of oil production and biomass processing. With a total of 2 patents, her work focuses on innovative methods that enhance the efficiency and sustainability of these industries.
Latest Patents
One of her latest patents is a "Method for determining the composition of water in low BSW oils." This invention addresses a method for characterizing water produced in oil samples containing water with contents below 0.5%. The process involves measuring the analytes of interest directly in the oil containing emulsified water. It requires filtrations to remove possible suspended solids that may interfere with the composition of the water. The proposed method provides methodologies with and without interference in the equilibrium by washing the oil with distilled water, allowing for accurate measurement of the analytes of interest directly in the oil.
Another significant patent is the "Method for pretreating lignocellulosic biomass." This invention describes a process for pretreating lignocellulosic biomass by contacting it with an ionic liquid consisting of a phthalic salt of dicholine. The process occurs in a weight ratio from 1:1 to 1:100 of biomass to ionic liquid, for a period ranging from 0.4 to 48 hours and at temperatures between 60 to 200°C. This pretreated biomass can then be utilized in an enzymatic hydrolysis process, enhancing the efficiency of biomass conversion.
