Japan-GTL Consortium Completes Construction of Demo Plant for New Gas-to-Liquids Process

The Japan-GTL consortium, formed in 2006 to commercialize a lower-cost gas-to-liquids GTL) process for the production of synthetic fuels and chemicals that does not require first removing carbon dioxide from the feedstock, has completed construction of its demonstration plant which will produce 500 barrels (about 80 kiloliters) per day. (Earlier post.) The opening ceremony took place on 16 April.

The Japan-GTL group includes oil developers Japan Petroleum Exploration (JAPEX) and INPEX Corp; refiners Nippon Oil and Cosmo Oil; engineering firms Chiyoda and Nippon Steel Engineering; and Japan Oil, Gas and Metals National Corp (JOGMEC), a state-run energy researcher.

The Japan-GTL process differs from technologies advanced by Sasol in South Africa and Shell in that it utilizes carbon dioxide gas as raw material and does not require any oxygen supply for the syngas reaction.

The GTL process uses innovative catalyst technology in both the syngas reformer and in the Fischer-Tropsch (FT) reactor. Syngas is produced by steam (H2O)/CO2 reforming rather than autothermal reforming (ATR) or non-catalytic partial oxidation (POX) used in other processes. The Fischer-Tropsch synthesis uses a slurry reactor with noble metal or non-noble metal catalysts, as compared to the copper or iron-based catalysts used in conventional processes.

The new GTL process is particularly effective when applied to natural gas feedstock containing 20-40 mol% of CO2. The most preferable CO2 content in the feedstock is around 30 mol%. In case the CO2 content is less than 30 mol%, additional CO2 can be supplied from other sources, such as flare gas, associated gas, remaining CO2 from Enhanced Oil Recovery operations or exhaust gas from oil refineries or LNG plants.

The process eliminates the need for three expensive components:

  • An oxygen supply plant;
  • A unit for CO2 separation; and
  • An H2 separation unit to optimize gas composition.

This makes the Japan-GTL process an attractive option to monetize stranded gas reserves which are located far from an existing gas market and have been left untapped due to the high cost of purification and gas transportation methods. Many gas fields are rich in CO2 and therefore difficult to develop commercially. As an example cited by one of the partners, JAPEX, the Natuna gas field in Indonesia has reserves of more than 200 TCF. Due to its high CO2 content (70%), however, the separation cost would have a major negative impact on the feasibility of the development.

The demo plant is scheduled to run for two years, and will be followed by the planned opening of a 30,000-bpd commercial plant near a gas field.



Everyday I read about some new fuel generating process or new plant that will produce fuel for transportation vehicles. Doesn't anyone get that we are destroying the earth's atmosphere and must stop this insane thinking and action. Children, will you please focus your attention, efforts and money on non-polluting wind, solar, nuclear and other electrical forms of energy and a transportation system that is based on electricity.


David, don't fret, the damage to the planet from 9+ billion people will far outway anything the ICE could ever do.



They are converting H20 + CO2 into liquid fuel. At the present the source for CO2 is natural gas, but there is no reason that in the future this source could be replaced sequestered CO2 from any number of carbon sequestration technologies that are being explored.

They have forged another link in the chain to complete the transportation CO2 recycle loop. If in fact they implement a technology to sequester atmospheric CO2 then the recycle chain will be one step closer completion.

The only question that the remains is what power are they using to run the plant? If this is some form of renewable resource then I would say that things were in pretty good shape.



Calling people "children", children who don't grasp your superior insights is a very effective tactic.

Have you contacted the Japan-GTL group, those who are actually doing this, and called them children? How did that work out?



Maybe he meant children, as in future populations?


JeffM: He didn't write it like that. But I knew he meant well.

So I endorsed everything he said.

I view these developments as positive because fossil fuel use isn't going to stop quickly. And if it did the disaster would be immense.
