The patent US12043587B2 outlines a novel process for converting C2-C5 linear or branched alcohols into C2-C7 olefins, which are valuable intermediates in the production of various chemicals and fuels. The process involves two main stages: first, the alcohols are reacted with a first catalyst, which is an alumina catalyst, in a reactor at temperatures ranging from 200°C to 500°C and pressures up to 30 bar. This reaction produces a second stream that is then treated with a second catalyst, specifically a doped zeolite catalyst, under similar temperature and pressure conditions. The process is designed to achieve a mass yield of at least 65% of olefins, which can include compounds such as ethylene, propylene, and butenes.
The patent further specifies that the alcohols used in the process can be bio-based and produced through fermentative methods, emphasizing a sustainable approach to olefin production. Notably, the process can utilize ethanol, propanol, and butanol, either individually or in combination. The second catalyst may also include specific dopants like boron and phosphorus, with their concentrations being less than 5 wt. % of the catalyst. The claims also highlight the potential for separating water from the reaction streams, which may enhance the efficiency of the overall process. This innovative method presents a significant advancement in the field of chemical engineering, particularly in the context of renewable feedstocks and sustainable chemical production.
