Abstract:

Ionic liquids (ILs) are ionic compounds composed of a bulky hetero-organic cation and a relatively smaller anion. This class of materials possesses many environmentally preferable properties, such as low vapor pressures, good solvency, diverse chemical properties, high ionic conductivities, and good heat transfer properties. This talk will describe how these novel materials are used successfully for the removal of sulfur and nitrogen compounds in hydrocarbons, which drastically improves the efficiency and economics of downstream fluid catalytic cracking and hydrocracking processes while minimizing air pollution. In addition to traditional ionic liquids with hetero-organic cations, the contaminant extraction applications of relatively inexpensive carbonium pseudo ionic liquids (CPILs), composed of bulky organic cations, will be discussed. An extraction cycle will be shown that includes efficient recycle of the ionic liquid. This talk will discuss the design, synthesis, separation, regeneration and catalytic application of ILs and CPILs for environmentally cleaner transportation fuels, gases, and petrochemicals.
