  • Process for the selective removal of nitrogen-containing compounds from hydrocarbon blends
    Patent number: 5675043
    Abstract: A process for the removal of nitrogen-containing compounds from a hydrocarbon blend using a solvent with a liquid-phase density at 25.degree. C. not less than 0.90 g/cm.sup.3, and a Hansen polar solubility parameter .delta..sub.P, and a Hansen hydrogen bonding parameter .delta..sub.H, such that at 25.degree. C.9.0(Cal/cm.sup.3).sup.1/2 <(.delta..sub.P +.delta..sub.H)<28.0(Cal/cm.sup.3).sup.1/2.The process is useful for purifying feedstocks to catalytic conversion processes, particularly etherification processes used in the production of ether-rich additives for gasoline.
