| 20120010304 | Method and System for Synthesizing Liquid Hydrocarbon Compounds - Provided is a method for synthesizing liquid hydrocarbon compounds wherein synthesizing liquid hydrocarbon compounds from a synthesis gas by a Fisher-Tropsch synthesis reaction. The method includes a first absorption step of absorbing a carbon dioxide gas, which is contained in gaseous by-products generated in the Fisher-Tropsch synthesis reaction, with an absorbent, and a second absorption step of absorbing a carbon dioxide gas, which is contained in the synthesis gas, with the absorbent which is passed through the first absorption step. | 01-12-2012 |

| 20110017337 | FLEXIBLE TUBE FOR TRANSPORTING CRYOGENIC FLUID AND STRUCTURE FOR DETECTING LEAKAGE OF FLUID IN TUBE - Provided is a flexible tube which is used to load fluid from a floating facility on the sea onto a tanker, which is suitable for transport of cryogenic fluid such as LNG, and which is capable of quickly and reliably detecting leakage of the fluid in the tube. Also provided is a structure for detecting leakage of fluid in a tube. A water impermeable and heat insulating layer is provided on the outer periphery of a heat insulating layer. The water impermeable and heat insulating layer, together with the heat insulating layer, thermally insulates LNG flowing through a corrugated tube from the outside of a flexible tube. Unlike the heat insulating layer, the water impermeable and heat insulating layer is poor in liquid permeability, and fluid such as LNG hardly permeates the water impermeable and heat insulating layer. That is, the water impermeable and heat insulating layer serves as a water impermeable layer between the inside and outside of the water impermeable and heat insulating layer. | 01-27-2011 |
| 20110015282 | PRODUCTION METHOD OF LIQUID HYDROCARBONS FROM NATURAL GAS - In a so-called GTL process for producing liquid hydrocarbons containing fuel oil by producing synthesis gas from natural gas, subsequently producing Fischer-Tropsch oil from the obtained synthesis gas by way of Fischer-Tropsch synthesis and upgrading the produced Fischer-Tropsch oil, the synthesis gas produced from a synthesis gas production step is partly branched at a stage prior to getting to a Fischer-Tropsch oil production step and high-purity hydrogen is separated and produced from the synthesis gas entering the branch line. All the separated high-purity hydrogen is supplied to an upgrading reaction step and consumed as hydrogen for an upgrading reaction. Additionally, the synthesis gas entering the branch line is subjected to a water gas shift reaction to raise the hydrogen concentration before the step of separating and producing high-purity hydrogen and the residual gas left after the separation may be circulated to the synthesis gas production step as raw material for producing synthesis gas. | 01-20-2011 |

| 20110003900 | PRODUCTION METHOD OF LIQUID HYDROCARBONS FROM NATURAL GAS - In a so-called GTL process of producing synthesis gas from natural gas, producing Fischer-Tropsch oil by way of Fischer-Tropsch synthesis of the obtained synthesis gas and producing liquid hydrocarbons containing fuel oil by upgrading, the synthesis gas produced from the synthesis gas production step is partly branched off prior to getting to the Fischer-Tropsch oil production step and the synthesis gas entering the branch line is subjected to a water gas shift reaction to raise the hydrogen concentration thereof. Subsequently, high-purity hydrogen is isolated from the synthesis gas and the residual gas left after the isolation is circulated to the synthesis gas production step and used as raw material for synthesis gas production. As a result, a significant improvement can be achieved in terms of raw material consumption per product of the entire process. | 01-06-2011 |
| 20100197814 | METHOD FOR EFFICIENT USE OF HEAT FROM TUBULAR REFORMER - In a GTL process of producing various kinds of hydrocarbon oils from natural gas, provided is improved heat efficiency in the case of using a steam reforming process or a carbon dioxide reforming process in the reforming. The process includes producing a synthesis gas by converting the natural gas and at least one of steam and carbon dioxide into a synthesis gas through a tubular reformer filled with a reforming catalyst, producing Fischer-Tropsch oil by subjecting the produced synthesis gas to a Fischer-Tropsch reaction, and upgrading in which the Fischer-Tropsch oil is subjected to hydrotreatment and distillation to produce various kinds of hydrocarbon oils, in which excess heat generated in the synthesis gas production is recovered, and the recovered heat is used as heat for at least one of hydrotreatment and distillation in the upgrading. | 08-05-2010 |

An impurity content of the catalyst can be in a range of approximately 0.01 mass % to 0.15 mass %. In particular, the exemplary method can include pre-treating the catalyst support to lower an impurity concentration of the catalyst support, and loading the metallic compound on the catalyst support after the pretreatment procedure. | 07-22-2010 |
| 20100001179 | METHOD OF PROCESSING ROCK WITH LASER AND APPARATUS FOR THE SAME - An object is to provide a method capable of boring a borehole even when quartz glass or silicon dioxide is deposited as molten dross by laser irradiation. A laser irradiation position of a workpiece is irradiated with a laser having wavelength of 1.2 μm or longer and a high factor of absorption into liquid, for example, a CO2 laser, from a laser oscillator through liquid. By high pressure generated in an advancing microbubble flow occurring in the liquid, molten dross is scattered. Thus, the processing, such as boring, of the rock is performed. | 01-07-2010 |
