Integrated Process for the Production of Vinyl Acetate from Acetic Acid Via Ethylene

Номер: US20120078006A1

Принадлежит: Celanese International Corp

This invention provides an integrated two stage economical process for the production of vinyl acetate monomer (VAM) from acetic acid in the vapor phase. First, acetic acid is selectively hydrogenated over a hydrogenating catalyst composition to form ethylene either in a single reactor zone or in a dual rector zone wherein the intermediate hydrogenated products are either dehydrated and/or cracked to form ethylene. In a subsequent second stage so formed ethylene is reacted with molecular oxygen and acetic acid over a suitable catalyst to form VAM. In an embodiment of this invention reaction of acetic acid and hydrogen over a hydrogenation catalyst and subsequent reaction over a dehydration catalyst selectively produces ethylene, which is further mixed with acetic acid and molecular oxygen and reacted over a supported palladium/gold/potassium catalyst.

Process for Ion Exchange on Zeolites

Номер: US20130129612A1
Автор: Hermann Luyken, Manuela Gaab, Rolf-Hartmuth Fischer
Принадлежит: BASF SE

Aspects of the present invention relate to an improved process for exchanging alkali metal or alkaline earth metal ions in zeolites for ammonium ions. For this exchange, aqueous solutions of ammonium salts, for example ammonium sulfate, ammonium nitrate or ammonium chloride, are currently being used. The resulting “ammonium zeolites” are calcined to convert them, with release of ammonia, to the H form of the zeolites suitable as a catalyst. Certain methods provided herein use ammonium carbonate instead of the ammonium compounds mentioned. As excess ammonium carbonate, in contrast to the nitrates, sulfates or chlorides, can be recycled in the form of carbon dioxide and ammonia, the amount of salt which has to be discharged is lowered significantly.

Regeneration of Oligomerisation Catalysts and Their Use

Принадлежит: ExxonMobil Chemical Patents Inc.

Deactivation of a zeolite catalyst during its use to catalyse the oligomerisation of olefins, is often believed to be a result of the formation of high boiling polymers as by-products. These by-products can remain on the catalyst and undergo further conversion to higher molecular weight polymers, which resemble heavy tars and in some cases even have the appearance of coke-like material. These materials can coat the catalyst particles and plug pores in the catalyst, thereby causing catalyst deactivation. The invention relates to an improved method for regenerating such a catalyst. 1. A process for the regeneration of a catalyst selected from ZSM-22; ZSM-57 , or mixtures thereof wherein the catalyst has been used for the oligomerisation of olefins comprising the following steps:i) heating the catalyst to a temperature in the range from 300° C. to 450° C. under an inert dry atmosphere; andii) heating the catalyst to a temperature in the range from 450° C. to 500° C. in a dry oxygen-containing atmosphere.2.
