Abstract
Pervasive requirement and utilization of reliable and readily available energy sources have led to the progressive depletion of conventional fossil fuel reserves. This has brought the unconventional fossil fuel reserves into focus. The unconventional petroleum resources are proven to hold a huge reserve around the world. One such resource is oil shale. Oil shale is a finely grained, porous, sedimentary rock which contains organic matter known as kerogen, concealed inside a mineral matrix. Kerogen is a complex organic compound which acts as the source of production of both conventional and unconventional petroleum and natural gases. On the application of heat, kerogen converts into bitumen which further breaks down into oil and gas. The most common and suitable method for production of oil and gas from oil shales as an alternative to conventional crude oil and natural gas is by retorting or pyrolysis. During oil shale pyrolysis process, the pyrolysis parameters significantly influence the yield and composition of the produced hydrocarbons. The mineral matters present in oil shale play a significant role in retorting or pyrolysis of oil shale. Inherent minerals such as silica, carbonate, pyrite etc. can drastically govern the heat transfer in oil shale, and influence the composition of products formed during pyrolysis of oil shale as an inherent catalyst.
