On the sulfur standard of carburant, the sulfur content of carburant in a broad sense can be divided into high sulfur, medium sulfur, low sulfur, ultra-low sulfur.

High sulfur generally refers to sulfur content above 2.0%

Medium sulfur generally refers to the sulfur content of 1.0% – 2.0%

Low sulfur generally refers to the sulfur content of 0.4% – 0.8%

Ultra low sulfur generally refers to sulfur content below 0.05%

The sulfur standard classification of carburants is mainly due to the different sulfur content of residuum in different raw materials and the different process temperature parameters of petroleum coke raw materials in the production and processing process, which leads to the different sulfur content of carburants.

However, in the process of using carburizer in various industries, the small difference in sulfur content will have a greater impact on the product. Only broad according to high sulfur, middle sulfur, low sulfur carburant quality division is not comprehensive, carburant sulfur standards can only be used as a reference for the selection of carburant.

The above is only a broad division of carburizing agent sulfur standards, specific in the selection of carburizing agent, sulfur content is a very important indicator, it is recommended to choose professional manufacturers.
