摘要: Disclosed are methods for synthesizing an ester or a carboxylic acid from an organic alcohol. To form the ester one reacts, in the presence of oxygen gas, the alcohol with methanol or ethanol. This reaction occurs in the presence of a catalyst comprising palladium and a co-catalyst comprising bismuth, tellurium, lead, cerium, titanium, zinc and/or niobium (most preferably at least bismuth and tellurium). Alternatively that catalyst can be used to generate an acid from that alcohol, when water is also added to the reaction mix.

摘要: Niobia- and tantala-doped ceria catalysts, their use in selective catalytic reduction (SCR) processes, and a compact after-treatment system for exhaust gases are disclosed. In some aspects, the catalyst comprises at least 91 wt. % of ceria and 0.1 to 9 wt. % of niobia or tantala doped on the ceria. While conventional SCR catalysts can deactivate at higher temperatures, the doped cerias, particularly ones having as little as 1 or 2 wt. % of Nb2O5 or Ta2O5, are activated toward NOx conversion by calcination. The doped cerias are also valuable for SCRF® catalyzed filter applications, including an after-treatment system that comprises a diesel particulate filter having inlets and outlets, and a dual-function catalyst coated on the inlets, outlets, or both. Compared with conventional SCR catalysts, the niobia or tantala-doped cerias enable a higher level of NO2 to be present.
摘要翻译: 公知了氧化铌和钽铝氧化物催化剂,它们在选择性催化还原(SCR)工艺中的应用,以及用于废气的紧凑的后处理系统。 在一些方面,催化剂包含至少91wt。 %的二氧化铈和0.1〜9wt。 在氧化铈上掺杂的氧化铌或钽的百分比。 虽然常规SCR催化剂可以在较高温度下失活,但是掺杂的二氧化铈,特别是具有少至1或2wt。 Nb 2 O 5或Ta 2 O 5的%通过煅烧而被NOx活化。 掺杂的二氧化铈对于SCRF®催化过滤器应用也是有价值的,其包括后处理系统,其包括具有入口和出口的柴油微粒过滤器,以及涂覆在入口或出口上的双功能催化剂。 与传统的SCR催化剂相比,氧化铌或氧化钽掺杂的铈氧化物可以提供更高水平的NO2。
