摘要: A process for preparing a peptized alumina having increased solids and acid contents and a decreased water content. The process comprising mixing a boehmite or pseudoboehmite alumina and acid with a high intensity, high energy mixer at a ratio of 0.16 to 0.65 moles acid/moles alumina for a time period sufficient to form a substantially free-flowing solid particulate having a solids content of 45 to 65 wt %. When used in catalyst manufacture, peptized alumina produced by the process provides an increased rate in catalyst production and decreased costs due to high solids concentration and the presence of less water to be evaporated.

摘要: Embodiments of the invention generally provide compositions of crystalline zeolite materials with tailored crystal habits and the methods for forming such crystalline zeolite materials. The methods for forming the crystalline zeolite materials include binding one or more zeolite growth modifiers (ZGMs) to the surface of a zeolite crystal, which results in the modification of crystal growth rates along different crystallographic directions, leading to the formation of zeolites having a tailored crystal habit. The improved properties enabled by the tailored crystal habit include a minimized crystal thickness, a shortened internal diffusion pathlength, and a greater step density as compared to a zeolite having the native crystal habit prepared by traditional processes. The tailored crystal habit provides the crystalline zeolite materials with an aspect ratio of about 4 or greater and crystal surfaces having a step density of about 25 steps/μm2 or greater.

摘要: The invention relates to a method for the operation of an exhaust gas aftertreatment system in an exhaust tract of an internal combustion engine. The exhaust gas aftertreatment system includes an SCR particle filter, a first reducing agent feed device for introducing the reducing agent into the exhaust tract upstream of the SCR particle filter, continuous regeneration of the SCR particle filter being possible using nitrogen dioxide as oxidizing agent, an SCR catalytic converter element arranged downstream of the SCR particle filter, and a second reducing agent feed device for introducing the reducing agent into the exhaust tract downstream of the SCR particle filter and upstream of the SCR catalytic converter element. A control unit regulates a quantity of reducing agent introduced into the exhaust tract by the first reducing agent feed device and/or by the second reducing agent feed device as a function of the temperature (TSCR-PF) of the SCR particle filter.
