diameter of from about 20 u03bcm to about 2000 u03bcm and any suitable length that enables reactor tubes 192 to function as described herein for example the hollow fibers can have a length of from about 10 cm to about 1 2 m in the coated tube configuration reactor tubes 192 are constructed from a steel material with a polymer coating applied thereon for example in one embodiment the steel tube has a length of about 20 cm a diameter of about 1 27 cm 0 5 in and a pore size of about 2 microns the polymer coating is applied on the inside of the steel tube at a thickness of from about 1 micron to about 5 microns thereby reducing the pore size of reactor tubes 192 to less than about 1 5 microns the carbon to liquids system described herein uses a fischer tropsch reactor constructed at least partially from a polymeric membrane material that enables the permeation of steam therethrough generally fischer tropsch reactors constructed of steel or other known materials facilitate minimizing catalyst deactivation by controlling the partial pressure of water produced during fischer tropsch synthesis and or by adding a certain quantity of titanium therein by constructing the fischer tropsch reactor of a polymeric membrane material that has high water to hydrogen and high water to carbon monoxide selectivity the water produced by the fischer tropsch reaction is removed before it can deactivate the reaction catalyst moreover the system described herein recycles the permeated steam in a flow of cooling natural gas to a vessel positioned upstream from the fischer tropsch reactor as such the permeated steam may be used as a reactant in the vessel and or.
