Latest Patents

One of Yvon Jestin's latest patents is a reactor designed for the nitration of hydrocarbons in the gaseous phase under pressure. This innovative reactor is specifically tailored for nitrating saturated hydrocarbons with fewer than five carbon atoms, either alone or in mixtures. The reactor consists of a reaction enclosure that houses a tube or pipe bank, which is in contact with a heated fluid that has a high heat-exchange capacity. The design ensures that the inside perimeter of the tubes does not exceed 800 mm, and if circular, it does not exceed 250 mm. The ratio of the surface area of the tube bank in contact with the reaction medium to the volume of the reaction enclosure is maintained between 1:1 and 3:1. Additionally, the reactor includes mechanical means to uniformly distribute the delivery of reaction medium gases across the various tubes, ensuring that the load difference between the most and least loaded tubes is no more than 10%. A tube bank injector is also incorporated to guarantee homogeneous mixing of all reaction fluids within the tube bank.
