Introduction of oil shale www.themegallery.com Oil shale, a fine-grained sedimentary rock containing kerogen, is widespread throughout the world. retorting oil shale to 1 produce shale oil and gas burning oil shale to 2 generate electricity Company Logo
Introduction of oil shale www.themegallery.com For the conventional oil shale retorting indus- try, there are some problems to solve, such as low shale oil yield, low degree of automation and severe environmental pollution, which restrict economic development. Company Logo
Introduction of oil shale www.themegallery.com Moreover, retorting and burning both leave behind a great deal of residue. The majority of the ash and semicoke is placed in landfills, which is considered to be a serious environmental problem. These problems have hindered development of the oil shale industry. Therefore, development of a comprehensive approach to oil shale utilization in China is needed. Company Logo
