The reporter learned from Southwest Chemical Design and Research Institute on the 30th that the "coal-based natural gas methanation pilot technology" jointly developed by the institute and the China National Offshore Oil & Gas Group has recently passed the results appraisal organized by the China Petroleum and Chemical Industry Federation. The world-leading technology has the advantages of low cycle ratio methanation process and high-performance methanation catalyst, which can produce high-quality, low-cost synthetic natural gas, and has industrial conditions.
Since 2009, the research and development of methanation technology and catalysts for coal-based natural gas has completed 350 m3/h of coal-based natural gas methanation tests; the largest domestic 2,000 m3/h coal-to-liquid natural gas methanation process has been started. Hourly pilot test, through 72 hours of continuous operation at full load assessment; completed 4000 hours methanation catalyst life test, built a catalyst industrial production equipment, to produce a qualified catalyst product with industrial raw materials. The company applied for 27 invention patents and obtained 12 authorizations.
The assessment results of this technology show that the total conversion of carbon monoxide and carbon dioxide is greater than 98.5%, the methanation selectivity is greater than 99.9%; the methane content of the product is greater than 97%, the carbon dioxide concentration is less than 1.0%, and the hydrogen concentration is less than 2%. Experts believe that the technology cycle is 20% to 50% lower compared with similar technologies at home and abroad; the catalyst has a low activation temperature, fewer side reactions, high heat-resistant temperature, strong carbon deposition resistance, good stability, and can reduce energy consumption per unit of product. Reduce equipment investment.
Hu Qianlin, deputy secretary-general of the China Petroleum and Chemical Industry Federation, stated that in China's primary energy use, the proportion of coal burning is as high as 68%, causing serious environmental pollution. The dependence on natural gas in China has been increasing year by year, and coal-to-synthetic natural gas will play an increasingly important role. As of the end of November this year, China's four coal-fired natural gas projects that are already under construction or under construction have all imported methanation technology abroad, and localization of coal-to-natural gas technology is imminent.

Separate design
The battery of this item is not installed on the solar panel as traditional outdoor solar lights do, but on the lamp body. With 16.5 feet long wire, it can be used outdoors and indoors.
Connect/Disconnect for flexible use
Disconnect it from the solar panel after fully charged for 8 hours, and you will get a portable lamp. Could be used as temporary light source for camping or be hung anywhere light needed.
Wide applications, Suitable for outdoor & indoor
This solar motion sensor light is made of high-density ABS and IP65 waterproof materials, not easily worn by bad weather (high temperature/rain/snows). Suitable for places where no power supplied like gazebo, shed, workshop, patio, porch, garden, chicken coop, basement, storage, barn, garage, yard, carport, backyard, camp, driveway, greenhouse, loft, van, attic, awning, grill area, pergola, tent, cabin, etc.
