摘要： An exhaust system for a diesel engine is provided. The exhaust system includes a component body with a surface, and a surface treatment disposed on some of the surface or all of the surface. The surface treatment is disposed so as to receive Diesel Exhaust Fluid (DEF) injected into the exhaust system during operation of the diesel engine. The surface treatment facilitates increased heat transfer to the received DEF to promote water evaporation and urea thermolysis of the received DEF.

摘要： STA-20, a molecular sieve having a new framework type, is described. STA-20AP (as prepared) can have an alkyl amine, such as trimethylamine, and 1,6-(1,4-diazabicyclo[2.2.2]octane) hexyl cations (from diDABCO-C6) as SDAs. A lower alkyl ammonium hydroxide, such as tetrabutylammonium hydroxide, can be used as a pH modifier for making SAPO STA-20. A calcined product, STA-20C, formed from as made STA-20 is also described. Methods of preparing STA-20, activating STA-20 by calcination, and metal containing calcined counterparts of STA-20 are described along with methods of using STA-20 and metal containing calcined counterparts of STA-20 in a variety of processes, such as treating exhaust gases and converting methanol to olefins are described.
