The instrument is designed and manufactured according to the requirements of the People’s RepublicofChina GB/T 17144 “Measurement method for residual carbon in petroleum products (micro method)” andASTM D4530 for the determination of carbon residue in petroleum products.The range of residual carbonmeasured by the instrument is: 0.10% (m/m) to 30.0% (m/m). The holding product of carbonresidueexceeding 0.10% (m/m) is equivalent to the measurement result of Kang’s carbon residue method(GB/T268).This instrument is also suitable for petroleum products whose residual carbon value is lessthan0.10% (m/m) and consists of distillate oil. However, 10% (V/V) distillation residue should be preparedbygb/6536 method first, and then used. This instrument is measured.

The instrument adopts a single-chip control system to command the coordinated operationof eachcomponent according to a preset procedure.The machine can receive the balance data; it canautomatically control the experiment process according to the standard requirements: the temperatureisraised at a constant rate of 10 ° C ~ 15 ° C and finally the temperature is constant within therangeof500 ° C ± 2 ° C;Automatically adjust the flow of nitrogen as required;Automatically performvariousactionsaccording to the timing, and each step will have different sounds, prompting the user to progresstheexperiment.The instrument is designed as a full Chinese interface. At the bottomof each interface, there are current operation prompts. The user does not even need to read the manual. Just press thecurrentprompt to test.
⑴ Main control board: Sigle-chip system, which controls the coordinated operation of all partsof thewhole machine. ⑵ Temperature control system: control the temperature of the coke box, automatically increaseat aconstant speed according to the standard and finally constant in the range of (500 ± 2) °C. ⑶ Nitrogen control system: Automatically adjust two different nitrogen flows according tostandardrequirements, 150ml/min or 600ml/min. ⑷ LCD: It is the interface of man-machine dialogue. All the information in the instrument communicateswith the user through the display, providing the current working status of the instrument at anytime,prompting the user to perform the current operation.
