class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>The production process of petroleum coke is relatively complex and is usually carried out in refineries. Firstly, crude oil has been processed by a series of distillation, cracking and other processing processes to obtain heavy oil components such as residual oil. These heavy oils are then subjected to delayed coking reactions at high temperatures (usually between 480 and 550) and high pressures (usually several megabits).<\/p>\n<p>In this process, heavy oil molecules undergo pyrolysis and condensation reactions to form coke and oil and gas. Oil and gas will be further separated and processed, while coke will be treated by cooling, cutting and other treatment to obtain petroleum coke products.<\/p>\n<p>&nbsp;<\/p>\n<h3><span class=\"ez-toc-section\" id=\"Raw_Materials_Used\"><\/span>Raw Materials Used<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>The main raw materials used in the production of petroleum coke are residual oil\u00a0or coke oil\u00a0in the process of petroleum refining. Residual oil is the heavy material part of crude oil after many times of distillation. Its composition is complex. It contains a large number of polymer hydrocarbons and a small amount of sulfur, nitrogen, metal and other impurities.<\/p>\n<p>The content of these impurities will have an impact on the quality of petroleum coke, for example, the high sulfur content of residual oil may also be higher, and environmental problems may be caused in subsequent applications.<\/p>\n<h2><\/h2>\n<h2><span class=\"ez-toc-section\" id=\"Different_types_of_petroleum_coke\"><\/span>Different types of petroleum coke<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>&nbsp;<\/p>\n<h3><span class=\"ez-toc-section\" id=\"Calcined_petroleum_coke\"><\/span>Calcined petroleum coke<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>It is a product obtained by heating raw petroleum coke at high temperature (generally 1200-1350\u2103). The calcining process can remove the volatiles from petroleum coke, improve its fixed carbon content, reduce resistivity, and improve its chemical stability and physical properties.<\/p>\n<p>After calcining, the petroleum coke density is large, and the pore structure is more stable. Its specifications vary according to different application requirements, and the price will vary depending on quality, specification and other factors.<\/p>\n<p>&nbsp;<\/p>\n<h3><span class=\"ez-toc-section\" id=\"Graphite_petroleum_coke\"><\/span>Graphite petroleum coke<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>Graphite fossil oil pyrographite fossil oil coke is an oil coke treated by high temperature graphitization (usually at 2500-3000\u2103).

In general, the calorific value of petroleum coke is about 30-35mj\/kg, which is competitive with traditional fuels such as <a href=\"https:\/\/en.wikipedia.org\/wiki\/Coal\" target=\"_blank\" rel=\"noopener\">coal<\/a>.<\/p>\n<p>However, the burning of pet coke will produce dust, sulfur dioxide and other pollutants. These need to be equipped with corresponding environmental protection equipment for treatment to meet strict environmental emission standards. Changes in prices relative to fuels such as coal will also affect fuel selection decisions for power generation companies.<\/p>\n<p>&nbsp;<\/p>\n<h3><span class=\"ez-toc-section\" id=\"Other_Industrial_Applications\"><\/span>Other Industrial Applications<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>In addition to the above major industries, have also been widely used in other industrial fields. For example, in the chemical industry, it can be used as raw material for producing silicon carbide and other chemical products.<\/p>\n<p>In the casting industry, it can be used to make casting core, etc.<\/p>\n<p>In the glass industry, it can be used as fuel for glass furnaces to provide the required heat.<\/p>\n<p>And its burning ash can be used as one of the raw materials of glass to participate in the glass production process.<\/p>\n<p>In these applications, the characteristics of petroleum coke, such as high carbon content and certain calorific value, have been fully utilized. And its specifications and quality requirements vary according to different industrial application requirements.<\/p>\n<p>&nbsp;<\/p>\n<h2><span class=\"ez-toc-section\" id=\"Conclusion\"><\/span>Conclusion<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>Petroleum coke is an important by-product of petroleum refining, which has many types and rich physical and chemical properties.
