Patent number: 6096116Abstract: A sorbent material, an activated carbon canister and a method are described which can be utilized to remove organic compounds from a vaporous stream with a relatively greater degree of safety, as compared to previously known methods. In the invention, essentially dry and wetted activated carbon particles are intermixed in a substantially homogeneous mixture which inhibits accidental combustion. The heat capacity of wetted carbon particles retards the heating of nearby unwetted particles, so as to inhibit the ignition of the nearby unwetted particles. The presence of wetted particles intermixed in the substantially homogeneous mixture has relatively little effect on the hydrocarbon adsorption performance of the mixture.Type: GrantFiled: December 15, 1998Date of Patent: August 1, 2000Assignee: BP Amoco CorporationInventors: George A. Huff, Jr., Om P. Mahajan, Don M. Washecheck, John A. Mahoney, Howard Wong, Stanley W. Sorrels

Patent number: 5609832Abstract: An exhaust gas emissions control system lowers cold-start hydrocarbon emissions by using heat exchange structure to lower the temperature of exhaust gas prior to the exhaust gas passing through a hydrocarbon adsorbent and using the extracted heat to heat a catalytic converter to its light-off temperature. In some embodiments, multi-component hydrocarbon adsorbers effective under different operating conditions further reduce cold-start hydrocarbon emissions.Type: GrantFiled: September 5, 1995Date of Patent: March 11, 1997Assignee: Amoco CorporationInventors: Rodney L. Mieville, Ronald A. Dictor, Eugene H. Hirschberg, Lawrence C. Robinson, Don M. Washecheck, Terrence A. Renner
