Title: Innovations of Johannes Borsboom
Introduction
Johannes Borsboom is a notable inventor based in Rijswijk, Netherlands. He has made significant contributions to the field of gas treatment, particularly in the removal and recovery of sulfur compounds. With a total of seven patents to his name, Borsboom's work has had a considerable impact on environmental technology.
Latest Patents
One of his latest patents is a process for the removal of sulfur compounds from gases. This invention focuses on the catalytic reduction of sulfur dioxide from a gas mixture that contains at least 10 vol. % of water. The process involves passing the gas mixture over a sulfur-resistant hydrogenation catalyst in sulfide form, at a space velocity of at least 2000 h⁻¹, in the presence of a reducing component, preferably hydrogen. The temperature range for this process is between 125°C to 300°C, followed by passing the gas mixture through a dry oxidation bed to oxidize sulfur compounds, particularly hydrogen sulfide, to elemental sulfur.
Another significant patent is for the recovery of sulfur from a hydrogen sulfide-containing gas. This process includes oxidizing part of the hydrogen sulfide with oxygen or an oxygen-containing gas to produce sulfur dioxide. The product gas is then reacted in at least two catalytic stages according to the Claus equation, followed by the catalytic reduction of sulfur dioxide in a catalyst bed downstream from the last Claus catalytic stage.
Career Highlights
Throughout his career, Johannes Borsboom has worked with several companies, including Comprimo B.V. and Gastec N.V. His expertise in gas treatment technologies has been instrumental in advancing methods for sulfur recovery and removal.
Collaborations
Borsboom has collaborated with notable colleagues such as Jan Adolf Lagas and Pieter H. Berben. These partnerships have contributed to the development of innovative solutions in the field of gas treatment.
Conclusion
Johannes Borsboom's contributions to the field of gas treatment through his patents and collaborations highlight his role as a significant inventor. His work continues to influence environmental technologies aimed at reducing sulfur emissions.
