Reflection on quality index of petroleum coke

The index range of petroleum coke is wide, and there are many categories. At present, only the carbon classification for aluminum can achieve its own standard in the industry. In terms of indicators, in addition to the relatively stable indicators of the main refinery, a large part of the domestic supply comes from the local refinery, and the raw materials of the local refinery are relatively flexible, so the indicators of petroleum coke produced will be adjusted frequently accordingly, and the price will be adjusted frequently with the pricing model of the respective refineries, so it is difficult to form a standardized and unified pricing model. Frequent and changeable prices and indicators bring uncertainty and risk to the cost control of the downstream demand side.

 

At present, the main reference index of carbon classification for aluminum is sulfur content and trace elements divided into 7 main indexes: 1, 2A, 2B, 3A, 3B and 3C. The sulfur content over 3.0% is regulated by enterprises themselves. At present, the classification of enterprise level is relatively rough, and most of them are used for reference in the industry.

In terms of the current price in November, the first week of November, in domestic refining replacement of indicators happen every day, weekly replacement and adjustment index frequency is more than 10 times, adjust the indexes of enterprises of the same frequency is uncertainty, relative to the downstream calcination, the demand such as anode, relatively stable index requirements demand end, facing the market quality is numerous, difference obvious, Indicators change frequently, and there is no relatively standard pricing method, this situation to petroleum coke demand enterprises to increase the procurement of considerable difficulty coefficient.

 

Taking the current market price as an example, the highest and lowest prices and the difference between the highest and lowest prices of each model in China except the northwest region at the beginning of November are shown in Table 1. Among them, the gap between the highest price and the lowest price of the same model is 5# petroleum coke, the gap is the largest for 4A petroleum coke, differential pricing and regional and wide range of indicators are related
