摘要：In heat transfer fluids, the carbon residue value is an indicator that provides its relative coking tendency. The micro carbon residue method is widely used because of the simple and convenient operation procedures and low pollution. However, when the carbon residue value is less than 0.1%, the sample needs to be prepared and then tested in the furnace. Therefore, this article aims at the measurement of carbon residue by the heat transfer fluids micro method. The heat transfer fluids is classified according to the product type and the maximum allowed temperature. The sample is prepared by pretreatment. In the method for determining micro carbon residue, whether the sample prepared by pretreatment is selective.
