Introduction

Carlos Alvarez Herrero is a notable inventor based in Tarragona, Spain. He has made significant contributions to the field of chemical engineering, particularly in the production of phosgene and isocyanates. With a total of 2 patents to his name, his work has implications for various industrial applications.

Latest Patents

One of his latest patents is a method for starting up and shutting down a phosgene generator. This invention relates to the operation of a phosgene generator that produces phosgene by reacting carbon monoxide with chlorine in the gas phase on an activated carbon catalyst. The method ensures that after a predefined operating period, the phosgene production is temporarily interrupted and can be resumed after a specific downtime. Notably, the activated carbon catalyst is freed of chlorine before the generator is started up, maintaining a maximum concentration of chlorine in the gas stream. This innovation is crucial for the safe production of polycarbonate and isocyanates.

Another significant patent by Herrero is a process for preparing isocyanates. This method addresses issues related to the formation of deposits in apparatuses during the activation and deactivation phases of the process. By ensuring a surplus of phosgene relative to the phosgenating amine during critical steps, the invention enhances the efficiency and safety of isocyanate production.
