摘要： The present invention provides a method for simplifying manufacture of a mixed alcohol or mixed oxygenate product from synthesis gas. The mixed alcohol or mixed oxygenate product contains ethanol and other oxygenates with two or more carbon atoms per molecule. The method includes stripping a portion of carbon dioxide and inert gases contained in a mixed alcohol synthesis reaction product using a methanol-containing stream, such as one produced as part of the method, as a medium to absorb said carbon dioxide and inert gases and recycling light products and heavy products to one or more of synthesis gas generation, mixed alcohol synthesis and separation of desired mixed alcohol or mixed oxygenate products from other components of a mixed alcohol synthesis stream. The present invention also provides downstream processing of the mixed alcohol or mixed oxygenate product by subjecting the product to a dehydration step in order to convert at least ethanol, preferably at least ethanol and propanol, to their corresponding olefins (e.g. ethylene and propylene).

摘要： The process for the distillation of a gas mixture comprising (meth)acrylic acid obtained from the gas-phase oxidation of at least one (meth)acrylic acid precursors is improved through the use of coupled distillation columns. In a first column, the gaseous mixture is dehydrated while in a second column, the dehydrated gaseous mixture is distilled into product, overhead and bottoms streams.

摘要： The present invention a process and apparatus for the production of methylene diphenyl diisocyanate (MDI) isomer mixtures with a low 2,2′-MDI isomer content and a high 2,4′-MDI isomer content. The resulting mixtures have an increased reactivity and are acceptable in food grade application due to the reduction in primary aromatic amines formed during the curing process. The process and apparatus also include controlling the amount of 4,4′-MDI, which is the most reactive isomer in the mixture allowing use in a wide variety of applications.
