Title: The Innovative Contributions of Roberto Gianna
Introduction
Roberto Gianna is a notable inventor based in Rome, Italy. He has made significant contributions to the field of chemical engineering, particularly in processes related to the removal of harmful substances from gases and fossil fuels. With a total of 5 patents to his name, Gianna's work reflects a commitment to advancing environmental sustainability.
Latest Patents
One of Gianna's latest patents involves a process for removing hydrogen sulfide (H2S) from gas. This innovative method utilizes a liquid solution containing ferric sulfate in an absorption column. The reaction occurs at room temperature and at pressures ranging from 1 to 1.2 atm, resulting in the reduction of ferric ions to two-valent iron and the oxidation of sulfide to elemental sulfur. The process includes a two-step filtration of the liquid exiting the absorption column, separating elemental sulfur from iron ions. The filtrate is then sent to a bioreactor for regeneration, allowing for the continuous reuse of the solution in the absorption column.
Another significant invention by Gianna is related to a strain of Arthrobacter sp. CBS 208.96, which is capable of selectively opening the C-S bond of sulfurated organic molecules in carbonaceous materials. This invention is crucial for the selective removal of organic sulfur from fossil fuels, showcasing Gianna's focus on improving fuel quality and reducing environmental impact.
