A novel catalytic membrane reactor for DME synthesis from renewable - PowerPoint PPT Presentation

Fed. funding: $2.3M Length 36 mo. A novel catalytic membrane reactor for DME synthesis from renewable resources Naomi Klinghoffer, Gas Technology Institute (GTI) Miao Yu, Rensselaer Polytechnic Institute (RPI) Xinhua Liang, Missouri University of Science and Technology (MS&T) CO 2 H 2 Project Vision We are solving the challenge of low conversion and product yield in processes that produce liquid fuels and chemicals from CO 2 and H 2 with our unique catalyst and reactor design. Project Impact Our process will enable production of clean burning liquid fuels that are safe and easy to handle from renewable energy, water, and CO 2 via a process that is modular and scalable.
