Title (EN) PROCESS FOR PREPARATION OF A CATALYST CARRIER
(FR) PROCEDE DE PREPARATION D'UN SUPPORT CATALYTIQUE
Abstract: front page image
(EN)This invention relates to catalyst carriers to be used as supports for metal and metal oxide catalyst components of use in a variety of chemical reactions. More specifically, the invention provides a process of formulating a low surface area alpha alumina carrier that is suitable as a support for silver and the use of such catalyst in chemical reactions, especially the epoxidation of ethylene to ethylene oxide. A precursor for a catalyst support comprises an admixture of an alpha alumina and/or a transition alumina; a binder; and either a solid blowing agent which expands, or propels a gas upon the application of sufficient heat, and optionally contains talc and/or water soluble titanium compound.
(FR)L'invention concerne des supports catalytiques à utiliser comme supports pour des composants catalytiques de métal et d'oxyde métallique à utiliser dans une pluralité de réactions chimiques. Plus précisément, l'invention concerne un procédé de formulation d'un support d'alumine alpha à faible surface active conçu comme un support de l'argent et l'utilisation d'un tel catalyseur dans des réactions chimiques, notamment l'époxydation d'éthylène en oxyde d'éthylène. L'invention concerne également un précurseur destiné à un support catalytique comprenant un mélange d'une alumine alpha et/ou d'une alumine de transition; un liant; et un agent de gonflement solide s'étendant ou propulsant un gaz au moment de l'application de chaleur suffisante et éventuellement un composant de titane soluble dans le talc et/ou l'eau.
