Adsorptive separation of hydrocarbons is commonly used as a low-energy alternative to industrial distillations. Recently, however, metal-organic frameworks (MOFs) are emerging as promising alternatives to traditional adsorptive solids. Researchers at Rutgers University have developed a series of novel zirconium-based MOFs for efficient separation of C6 alkane isomers. The Zr-MOFs have an adsorption capacity exceeding the current industry benchmark zeolite 5A; further, some configurations permit discrimination between mono and multi-branched hydrocarbon isomers. Market Applications: Petroleum refining for production of high-RON gasoline Industrial reactions requiring separation of linear and branched hydrocarbons Separation of mono- and di-branched hydrocarbon isomers Advantages: Separation efficiencies and adsorptive capacities exceeding the industry standard High degree of mono and dibranched alkane separation selectivity Intellectual Property & Development Status: Patent pending. Available for licensing and/or research collaboration.
