TL;DR: In this article, a hydrocarbon containing formation may be treated using an in situ thermal process using heat input into the formation to raise a temperature of the formation at a selected rate.
Abstract: A hydrocarbon containing formation may be treated using an in situ thermal process. Hydrocarbons, H 2 , and/or other formation fluids may be produced from the formation. Heat may be applied to the formation to raise a temperature of a portion of the formation to a pyrolysis temperature. Heat input into the formation may be controlled to raise a temperature of the formation at a selected rate.

TL;DR: It is found that nitrogen doping occurs during cellulose pyrolysis under NH3 at as low as 550 °C and at 700 °C or above, N-doped carbon further reacts with NH3, resulting in a large surface area (up to 1973).
Abstract: Here, we present a simple one-step fabrication methodology for nitrogen-doped (N-doped) nanoporous carbon membranes via annealing cellulose filter paper under NH3. We found that nitrogen doping (up to 10.3 at %) occurs during cellulose pyrolysis under NH3 at as low as 550 °C. At 700 °C or above, N-doped carbon further reacts with NH3, resulting in a large surface area (up to 1973.3 m2/g). We discovered that the doped nitrogen, in fact, plays an important role in the reaction, leading to carbon gasification. CH4 was experimentally detected by mass spectrometry as a product in the reaction between N-doped carbon and NH3. When compared to conventional activated carbon (1533.6 m2/g), the N-doped nanoporous carbon (1326.5 m2/g) exhibits more than double the unit area capacitance (90 vs 41 mF/m2).

TL;DR: In this article, the surface morphology of pyrolysis of used tires was found to be similar to that of commercial carbon black (CB{sub P} in terms of inorganic compounds, especially ZnO and S.
Abstract: The vacuum pyrolysis of used tires enables the recovery of useful products, such as pyrolytic oil and pyrolytic carbon black (CB{sub P}). The light part of the pyrolytic oil contains dl-limonene which has a high price on the market. The naphtha fraction can be used as a high octane number component for gasoline. The middle distillate demonstrated mechanical and lubricating properties similar to those of the commercial aromatic oil Dutrex R 729. The heavy oil was tested as a feedstock for the production of needle coke. It was found that the surface morphology of CB{sub P} produced by vacuum pyrolysis resembles that of commercial carbon black. The CB{sub P} contains a higher concentration of inorganic compounds (especially ZnO and S) than commercial carbon black. The pyrolysis process feasibility looks promising. One old tire can generate upon vacuum pyrolysis, incomes of at least $2.25 US with a potential of up to $4.83 US/tire upon further product improvement. The process has been licensed to McDermott Marketing Servicing Inc. (Houston) for its exploitation in the US.
