摘要: The present invention relates to a process for the separation of ethanol from a mixture thereof with ethyl tert.-alkyl ether employing a selective adsorbent comprising a mixture of sodium zeolite Y in combination with alumina wherein the percentage of the sodium zeolite Y ranges between 10 and 40 wt-%. The invention reduces the cost of this separation which is complicated by an azeotrope formation between the alcohol and the ether.

摘要: A method for forming a blend of ethers from a blend of alcohols includes a step of reacting a hydrocarbon-containing gas with an oxygen-containing gas to form first product blend. The first product blend includes a blend of partially oxygenated compounds. The blend of partially oxygenated compounds is provided to a reactive distillation station where it is converted a second product blend. The second product blend typically includes a mixture of ethers. An apparatus implementing the method is also provided.

摘要: A process for the acid-catalyzed dehydration of ethanol, the process comprising the steps of distilling an ethanol feedstock (101) comprising at least one nitrogen-containing contaminant to form an overhead stream (102) and a bottom stream comprising ethanol (103), wherein the distillation has a reflux ratio of at least 20:1; and reacting the bottom stream in the presence of an acid catalyst to form a product stream comprising ethylene.
