    Abstract: The invention relates to a method for producing linear alpha olefins by means of an isomerising metathetical reaction and ensuing ethenolysis. The method comprises the following steps: i) a C4-C10 olefin fraction is introduced into an isomerising metathesis reaction; ii) the mixture obtained is separated into a) a C2-C3-olefin fraction, b) a fraction containing olefins having the desired carbon count, c) a light fraction containing olefins having a carbon count of C4 or above, but below the carbon count of the desired fraction b) and, d) a heavy fraction containing olefins having a carbon count which is above the carbon count of the desired fraction b); iii) the light fraction c) and optionally the heavy fraction d) are redirected into the isomerising metathesis reaction i); iv) the fraction b) and optionally the fraction d) are introduced into an ethenolysis reaction; and v) the alpha olefin fraction produced in iv) is isolated. Linear C8-C12 alpha olefins can be especially produced using said method.
