Studying Ether Formation From Branched Alcohols

While we are currently investigating the "Exxon-Mobil" MTG " process (methanol-to-gasoline) with modified zeolite catalysts ( 200-250 deg. C in an autoclave 1-2 hrs. as a starting point), we are also looking at the possibility of forming branched aliphatic ethers ( from guerbet alcohols) with "modified activated carbon"  at 110-120 deg. C ( overnight?) in a lab oven. Our starting study involves the use of 2-ethyl-1-hexanol.
