Petroleum coke Wikipedia
Petroleum coke Petroleum coke, abbreviated coke, pet coke or petcoke, is a final carbonrich solid material that derives from oil refining, and is one type of the group of fuels referred to as cokesPetcoke is the coke that, in particular, derives from a final cracking process—a thermobased chemical engineering process that splits long chain hydrocarbons of petroleum into 1996年1月1日 In addition, green coke volatility levels can be qualitatively related to calcined coke quality; that is, the lower the green coke volatile level, the more anisotropic the coke Typically, green premium cokes have volatile levels of less than 5% (wgt), green regular cokes have volatile levels of 68% (wgt) and green isotropic cokes have volatile levels of 10% (wgt) The characterization of petroleum coke ScienceDirect2023年12月26日 Petroleum Coke D6970 Practice for Collection of Calcined Petroleum Coke Samples for Analysis D8145 Practice for Sampling of Green Petroleum Coke 3 Terminology 31 De®nitions: 311 For de®nitions of terms used in this test method, refer to Terminology D4175 312 calcined petroleum coke, nÐpetroleum coke that hasHardgrove Grindability Index (HGI) of Petroleum Coke12001年9月1日 A kind of petroleum coke was burnt in a bubbling fluidized bed combustor (BFBC) The effect of limestone batch feed for SO2 removal on NOx emission was evaluatedEffect of Batch Feeding of Limestone on NO x and SO 2
