Methods and systems for particulate matter removal from a process exhaust gas stream

A method of reducing particulate matter from an exhaust gas from a process for the production of carbon black, comprising:

• producing carbon black and the exhaust gas in the process for the production of carbon black;
• collecting the carbon black, wherein collecting the carbon black comprises filtering to separate the carbon black from the exhaust gas, thereby producing a separated exhaust gas;
• combusting the separated exhaust gas to thereby produce a combusted exhaust gas comprising particulate matter;
• and
• catalytically oxidizing at least a portion of the particulate matter of the combusted exhaust gas by passing the combusted exhaust gas through a vessel comprising an oxidation catalyst, thereby removing at least a portion of the particulate matter from the combusted exhaust gas to thereby produce an oxidized exhaust gas.
