| 20150246857 | PROCESS FOR PREPARING LINEAR BUTENES FROM METHANOL - The invention relates to a method for producing linear butenes from methanol. The problem addressed is that of specifying such a method in which the methanol used is converted, to the largest possible extent, into butenes. The problem is solved by combining a methanol-to-propylene process with a metathesis reaction by means of which the propene obtained from the methanol is converted into linear butenes. | 09-03-2015 |
