This paper introduces the feature of JNOC GTL process and part of the results of Yufutsu GTL pilot plant test. JNOC GTL process and catalysts have been developed by collaboration with five Japanese companies such as Japan Petroleum Exploration Co., Ltd, CHIYODA CORPORATION, COSMO OIL Co., Ltd, NIPPON STEEL CORPORATION, and INPEX CORPORATION. We succeeded in producing the first GTL from natural gas November in 2002 at Yufutsu GTL pilot plant. We have been verifying the performance of syngas catalysts and FT catalysts and seizing the engineering data for scale-up under the pilot plant's operation.
