The problem with GTL and CTL is the poor thermal efficiency of the the processes. GTL is used at Qatar where as a "stranded" gas source, it is easier to transport normal petroleum liquids than liquefy and transport LNG. CTL was introduced in wartime Germany to keep the tanks rolling and in South Africa where it avoided sanctions. Sasol is now licensing the process to China.

Time for a reality check!
