What is the carbon conversion rate in gasification? How to calculate it? Answer: The carbon conversion rate refers to the percentage of the total amount of carbon that participates in the reaction, relative to the amount of carbon in the coal fed into the furnace. The carbon conversion rate can be calculated by dividing the amount of carbon converted into gas by the amount of carbon in the coal fed into the furnace, that is, Xc = (carbon content in 1 m3 of gas under standard conditions, including tar, etc.) × gas production rate ÷ (1 kg of carbon in the feed coal) × 100% ； It can also be calculated by deducting the carbon content in fly ash and slag, that is, Xc = 100% – (carbon content in fly ash + carbon content in slag) ÷ carbon content of the coal fed into the furnace × 100%

It can be calculated by dividing the amount of carbon converted into gas by the amount of carbon in the coal fed into the furnace, or it can be calculated by deducting the amount of carbon present in the fly ash and slag.
The carbon conversion rate is defined as the ratio of the carbon content in the gas to the total carbon content in the coal. The calculation method is: Carbon conversion rate = 1 – Carbon content in the ash / Carbon content in the coal feedstock
Carbon conversion rate = Total carbon content in the exhaust gas / Total carbon content in the coal fed into the furnace * 100%
The ratio of carbon content in gas to total carbon content in coal
The carbon conversion rate is defined as the ratio of the carbon content in the gas to the total carbon content in the coal. The calculation formula is: Carbon conversion rate = Carbon reacted / Carbon content in the feed coal; or Carbon conversion rate = 1 – Carbon content in the ash / Carbon content in the feed coal
Carbon conversion rate refers to the percentage of the total amount of carbon involved in the reaction relative to the amount of carbon in the coal fed into the furnace. The carbon conversion rate can be calculated by dividing the amount of carbon converted into gas by the amount of carbon in the coal fed into the furnace, that is, Xc = (carbon content in 1 m3 of gas under standard conditions, including tar, etc.) × gas production rate ÷ (1 kg of carbon in the feed coal) × 100% ； It can also be calculated by deducting the carbon content in fly ash and bottom slag, that is, Xc = 100% – (carbon content in fly ash + carbon content in bottom slag) ÷ carbon content of the coal fed into the furnace × 100%.
It is expressed as the percentage of the amount of carbon entering the syngas relative to the total amount of carbon in the feed coal. Samples of fly ash and bottom slag were taken to determine their carbon content; the ratio of this value to that of the raw coal represents the unconverted carbon percentage. Subtracting this value from 100% gives the carbon conversion rate.
Carbon conversion rate refers to the percentage of the total amount of carbon involved in the reaction relative to the amount of carbon in the coal fed into the furnace. The calculation method is the ratio of the total carbon in the inlet gasified stream to the molar amount of carbon in the outlet gasified stream, that is, total carbon in coal: CO + CO2 + CH4 / total carbon in coal; flow rates also play a role in this calculation.
The carbon conversion rate is defined as the ratio of the carbon content in the gas to the total carbon content in the coal. Carbon conversion rate = amount of carbon that has reacted / carbon content in the coal fed in. Carbon conversion rate = 1 – carbon content in the ash / carbon content in the coal fed in. Generally, the composition of syngas is analyzed online using a mass spectrometer
