摘要： The present invention provides an ethylene separation process comprising an first and second deethanizer columns and an acetylene converter, thereby providing an ethylene stream having a purity of 99 wt % or more to the middle of an ethylene separation column. The present invention increases the production amount of ethylene and also reduces energy consumption by passing the feed through a preliminary ethylene separation process, without having to change existing facilities in which an acetylene converter is provided downstream of the deethanizer column.

摘要： Processes and apparatuses for producing a C8 aromatic isomer product are provided. The processes comprise introducing a raffinate product stream comprising C8 aromatic isomers to an isomerization unit to provide an isomerized stream. The isomerized stream is separated to provide a first stream comprising C8 naphthenes and C7 aromatic hydrocarbons and a second stream comprising C8 aromatic isomers. The first stream is passed to an extractive distillation column to provide a recycle feedstream comprising the C8 naphthenes and an extract stream comprising the C7 aromatic hydrocarbons. The recycle feedstream is passed to the isomerization unit.

摘要： The present application discloses novel amino-sulfide metal catalysts for organic chemical syntheses including hydrogenation (reduction) of unsaturated compounds or dehydrogenation of substrates. The range of hydrogenation substrate compounds includes esters, lactones, oils and fats, resulting in alcohols, diols, and triols as reaction products. The catalysts of current application can be used to catalyze a hydrogenation reaction under solvent free conditions. The present catalysts also allow the hydrogenation to proceed without added base, and it can be used in place of the conventional reduction methods employing hydrides of the main-group elements. Furthermore, the catalysts of the present application can catalyze a dehydrogenation reaction under homogenous and/or acceptorless conditions. As such, the catalysts provided herein can be useful in substantially reducing cost and improving the environmental profile of manufacturing processes for a variety of chemicals.
