Carbon black10 Dec 2024 11:33
Has anyone considered how “green” this carbon black is from ferro alloy?
A quick on google search Furnace process reveals
This process uses incomplete combustion of heavy hydrocarbons to produce carbon black. It has a high carbon dioxide footprint, producing around 2.3 tons of carbon dioxide-equivalent per ton of carbon black.
Plasma torch pilot scale
A 150 kW plasma torch pilot scale test program in 1989 used 2100 kW of electricity and 1000 Nm3/h of natural gas to produce 500 kg/h of carbon black.
Methane pyrolysis plasma process
This process can achieve a methane feedstock conversion of over 99%, a hydrogen selectivity of over 95%, and a solid recovery of over 90%. The first commercial plant of this process had an energy intensity of 25 kWh per kg of hydrogen produced.
Hydrogen fuel
Using hydrogen as fuel instead of natural gas can reduce the carbon dioxide footprint by 19%. However, the current prices of hydrogen can increase the cost of carbon black by 47%..
Ferro alloy resources carbon black comes as a by-product of the vanadium extraction process, I’m sure all these manufacturers requiring the carbon black will be falling over themselves to get their hands on it just because the “green”properties it has.
