  • Patent number: 5660800
    Abstract: 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.

  • Patent number: 4297205
    Abstract: There is disclosed a catalyst for the reforming of hydrocarbon streams. This catalyst comprises iridium as a hydrogenation component on a support of zirconia and alumina. The support comprises zirconia in an amount of about 3 wt.% to about 15 wt.% zirconia or at least 60 wt.% zirconia. The iridium is present in an amount of about 0.05 wt.% to about 1.5 wt.%, calculated as the metal and based upon the total weight of the catalyst.Also disclosed is a reforming process, which process comprises contacting a hydrocarbon stream in a reaction zone under reforming conditions and in the presence of hydrogen with the above-described catalyst.

  • Patent number: 4048058
    Abstract: There are disclosed a method for sulfiding a multi-metallic catalyst or a bi-metallic catalyst and a method for initiating the reforming of a petroleum hydrocarbon feedstock in a reforming reaction zone containing a multi-metallic catalyst or a bi-metallic catalyst.The method for sulfiding is employed when a hydrogen-rich gas containing light hydrocarbons is used in the sulfiding of the catalyst. The method comprises passing a stream of said gas over said catalyst at a temperature of about 350.degree. F. to about 470.degree. F., injecting a sulfur-containing compound into the stream of gas up-stream from said catalyst in order to provide a sulfur-carrying gas, and contacting said catalyst with said sulfur-carrying gas at said temperature for a time that is sufficient to provide a sulfur concentration on said catalyst of about 0.1 to about 2.5 moles of sulfur per mole of total active metal. A typical sulfur-containing compound is dimethyl sulfide.
