In the test, a 200 g sample of –21 mm to +19 mm particle range coke is heated at 1100 °C under 1 atmosphere pressure of carbon dioxide for 2 hours. The coke is preheated and cooled under nitrogen and the weight loss during reaction is measured. The percentage weight loss is known as the reactivity (CRI). The reacted coke is placed in an I-type drum (no lifters) and subjected to 600 revolutions in 30 minutes. The percent of carbon material removed from the drum that is +10 m… WebAdvanced designed Coke Reactivity Applied Test System in conjunction with the Coke Strength Tumbler Test procedure provide a high quality, precision system for …

WebNov 16, 2016 · Coke strength after reaction (CSR) was predicted using linear regression of the CSR and CRI data. The estimated CSR was in good agreement with the CSR data. The sensitivity analysis of coal properties to CRI was also performed using the developed kinetic model. The model was successfully applied for coal blending to predict CRI of the … WebCoke; Published: January 2007; Relationship between CSR and CRI and comparison of these parameters for box and commercial cokes.

Modifying CRI and CSR values of coke SpringerLink
WebDec 8, 2024 · The coke yield, coke reactivity (CRI), and coke strength after reaction (CSR) were measured. As shown in Table 1, the addition of 0.7% GL can effectively reduce the CRI and increase the CSR of the coke. The experimental results prove the effective role of GL in CRI reduction in the subsequent industrial coking experiments. WebTwo indices, coke reactivity index (CRI) and coke strength after reaction (CSR), are determined using the reacted coke residue. The weight loss after reaction determines the CRI. The weight retained after sieving the tumbled reacted coke in a designated number of revolutions over a designated turning rate determines the CSR. 4. WebJan 11, 2024 · Research shows that the coke reaction rate at the coke weight loss of 25% (CRR25) and coke strength after reaction (CSR25) can explain the stable operation of a … can bank of america atms dispense $10
