Title: **Walcondiney Pereira Nunes: Innovator in Fluid Catalytic Cracking**
Introduction
Walcondiney Pereira Nunes is an accomplished inventor based in Rio de Janeiro, Brazil. He has made significant contributions to the field of chemical engineering, specifically in the area of fluid catalytic cracking, which is essential for refining petroleum products.
Latest Patents
Walcondiney holds one patent titled "Apparatus and process for downflow fluid catalytic cracking." This innovative apparatus comprises a regenerated catalyst riser that carries a regenerated catalyst along with a carrying fluid. The design features a crossover section leading to a distributor that efficiently centrifuges gas, separating the catalyst from the carrying fluid. The catalyst is then directed to a downflow reactor equipped with a distributing basket, designed with perforations to optimize the process. This reactor upper section includes feed injectors that atomize the feed, enhancing its vaporization and mixing with the catalyst. Following the cracking reaction, the products are separated, and the spent catalyst is routed to stripping and regeneration sections, thus enabling a comprehensive FCC process.
