Oil shale resources have broad prospects for development
- Low reserves and high production costs High added value of deep processing
As the prices of traditional energy such as oil, coal, and natural gas continue to rise, apart from the booming new industries such as solar energy, wind energy, bio-energy, and coal chemical, the development of coal and oil exploration has also received increasing attention. The CBM and oil pages Rock resources development is quietly heating up. Shandong Longkou Mining Group invested RMB 2.6 billion in the Longfor oil shale oil refining project. After intense trial production in the previous stage, it has produced more than 5,500 tons of crude oil. This indicates that Longyuan Group has made significant progress in the concept of relying on local rich oil shale to build a coal-electricity-oil recycling economy industrial chain under the adverse conditions of reduced coal resources.
Oil shale, also known as kerogen shale, is produced primarily by algal blooms and other plankton through corrosive and coalification. Shale oil “extracted†from oil shale is a man-made oil that is often referred to as low-temperature carbonization. After shale oil is further processed and refined, liquid fuels such as gasoline, kerosene, and diesel can be obtained. Its current price is as high as 4,700 yuan per ton, and it is still in short supply.
The reserves of oil shale are very abundant. Shale oil reserves in oil shale around the world total about 366.2 billion tons, which is at least 50% more than the traditional oil resources. The reserves of oil shale resources in China are expected to exceed 480 billion tons and the amount of shale oil resources contained is 29 billion tons, ranking fourth in the world. At present, the proven reserve of oil shale in China is more than 30 billion tons, mainly distributed in Jilin, Liaoning, and Guangdong. Among them, oil shale reserves in Jilin Province are over 17 billion tons, and the reserves are the highest in the country.
Through the development of oil shale, some conventional oil and gas can be replaced to ease the pressure on China's energy supply. Experts predict that with the growing shortage of traditional resources, the status of man-made oil will become increasingly important. In the next decade or two, there will be unprecedented development in the shale oil industry and the outlook is quite promising.
In 2007, the US World Oil Shale Annual Meeting calculated that when the oil reaches 25 US dollars per barrel, oil shale underground cooling and dry distillation can be profitable, when the oil price reaches 35 US dollars per barrel when the oil shale mining out the use of warm distillation distillation Profitability can be achieved. Due to the high oil recovery rate of this technology, it is currently used more.
Longfu Oil Shale Oil Refining Project is one of the five key projects invested by Dragon Mining Group this year. The total investment of the project is 2.6 billion yuan. It can annually process 1.8 million tons of oil shale, refine 225,000 tons of crude oil and 1.22 million semi-coke products. Ton; supporting power plant 3 × 135 MW, annual power generation of about 3 billion kwh. After the completion of the project, the annual sales income will be 3.655 billion yuan, which will become China's first oil shale recycling demonstration project. The Dragon Group will also enter the field of oil refining and power generation on a large scale, becoming one of the few large-scale energy groups with coal, electricity and oil industries.
As the only seashore coal base in the country, Dragon Group has a very rich oil shale reserves, has proven geological reserves of 191.4 million tons, recoverable reserves of 60.15 million tons, with large reserves, high oil content, high calorific value, volatile High, high added value, low sulfur content, low nitrogen content, low pollution, etc.
According to report, in addition to the Longfor oil shale oil refinery project, Guangdong Yuedian Oil Shale Mine Joint Venture Co., Ltd. of Yuede Power Holdings was also recently announced in Maoming City. The project has a planned total capacity of 1200 MW. Invested 3.7 billion yuan, the first phase of construction of two 200 megawatts of oil shale circulating fluidized bed units, and supporting the construction of an oil shale mining area with an annual production capacity of 6 million tons. Jilin Hongsheng Weiye Company has entered into substantive operation in 2007. In October of that year, it acquired a local oil shale demonstration power plant and three oil shale mines. This year, it plans to mine 1.2 to 1.5 million tons of ore, next year shale ore The mining volume will reach 3 million tons. Liaoning Chengda will cooperate with Fuxin Mining Group to build three pillar industries of coal, basalt fiber and shale oil. On December 7 last year, Fuxin Mining Group and the Huadian City Government of Jilin Province formally signed a contract to carry out comprehensive development of oil shale resources. The total investment of the project will reach 5.7 billion yuan.
