Mesoporous MFI-Zeolite Catalysts for Aromatics Production

Executive SummaryThere is a need for a green, renewable, and sustainable route to produce chemicals currently made from petrochemical feedstocks. MSU researchers have developed a new catalyst system for converting biomass to aromatics. The aromatics can be further transformed into downstream chemicals such as terephthalic acid, which can be used in...

Efficient Hydrocyclone for Liquid-Liquid Separation

Executive SummaryDue to environmental concerns, discharge of water from oil and gas industries is required to maintain oil levels between 10 – 30 ppm. Complying with these standards leads to significant expenses for the industry. A new hydrocyclone design developed at MSU makes it possible to exceed these requirements while being much more cost-effective...
