Low-temperature pyrolysis of the native heavy oil in the presence of the iron-based catalyst

© SGEM 2017. All Rights Reserved. Currently heavily developed light oil resources are being depleted, and the energy consumption is increasing. In this context, the task of developing the tight oil reserves is relevant and will soon become an essential resource for stabilizing and increasing the oil production. The share of tight oil (including heavy crude oil) is steadily increasing in the overall balance. Oil production will therefore be at the expense of these oil revenues in the coming years. These hydrocarbon resources are referred to as non-traditional, as they require the use of technologies and methods that differ from traditional methods of producing light oil. One such method is the thermal steam treatment of formation. It is characterized by the injection of the calculated volume of the heat carrier through the injection wells, the creation of a thermal rim and its subsequent movement using the unheated water in the reservoir towards the wells. However, the use of various complementary techniques, such as the injection of catalytic systems, will increase energy efficiency and intensify the recovery of heavy oil. The relevance of such research is unquestionable. This work has examined the structural changes in the interchangeability of the alternative oil contained in the oil-bearing sandstone sample, with impact on the latest process of catalytic and non-catalytic aquathermolysis. The sandstone specimen is taken from the Volga-Ural Province (Russia)

Structural changes of heavy oil in the composition of the sandstone in a catalytic and non-catalytic aquathermolysis

All rights reserved.Currently in connection with exhaustion of actively developed resources of light crude and the increasing consumption of energy carriers the development task solution of scavenger oil which will soon become the most important resource of stabilization and increase of oil production is relevant. The share of scavenger oil which,in particular,treatsuperviscous heavy oil steadily grows in overall balance therefore in the next years the gain of oil extraction will be provided at the expense of such naptha. It is accepted to call these resources of hydrocarbons non-conventional as their extraction requires application of the technologies and methods different from traditional methods of light oil production. One of such methods is steam impact on the layer which is characterized by downloading settlement volume of the heat carrier through delivery wells,creation of a thermal fringe and its subsequent advance by not heated water on layer towards production wells. At the same time use of various additional receptions,in particular,forcing of catalytic systems will allow to increase energy efficiency and to intensify process of heavy oil extraction. Relevance of such researches does not raise doubts. In this work the heavy native oil structural changes are studied; they lie in a sample of petrosaturated sandstone of the Volga-Ural province,being impacted by process of catalytic and not catalytic aquathermolysis

Methane pyrolysis on sponge iron powder for sustainable hydrogen production

Methane pyrolysis is one of the possible methods to produce low-carbon hydrogen. One of the most promising catalysts for methane pyrolysis is Fe due to its availability, relatively low cost and high working temperature. In the presented paper, the methane pyrolysis on unsupported (without a carrier) sponge iron in the form of powder was studied in the temperature range of 700–1100 ◦ C. Methane pyrolysis was carried out in a stainless-steel tube reactor with an inner diameter of 10 mm. The reactor was heated locally by propane burner, the length of the heated zone was about 8 cm along the reactor tube. Methane feed rates were about 50, 100, and 200 ml/min, and the residence time of methane in the 8 cm long reaction zone was about 4, 2 and 1 s, respectively. The hydrogen yield increased with an increase in the temperature and a decrease in methane feed rate. At 700–800 ◦C, the hydrogen yield did not exceed 20%. At 900 ◦C, the yield reached 28.6% at a residence time of about 4 s. At 1000 ◦C, hydrogen yield was about 40 and 66.5% at a residence time of about 1 and 4 s, respectively. At 1100 ◦C, hydrogen yield varied in the range of 70–85%. The use of a catalyst increased the hydrogen yield by 81% compared to the experiment without a catalyst at 1100 ◦C. The catalytic effect of sponge iron powder can be used in the development of methane pyrolysis plants
