CARBON BLACK INDUSTRY: CURRENT SCENARIO, FUTURE TECHNOLOGY AND TRENDSPresented by:-SANJANA BHATTACHARYYACHEMICAL ENGINEERING4TH YEAR Roll: 115537HERITAGE INSTITUTE OF TECHNOLOGYINTRODUCTIONNearly pure form of carbon particles97% carbon in aciniform arrangementFormed by incomplete combustionProperties: Particle size, structure, surface chemistry, aggregate distribution

PROCESSMain two methods: furnace black, thermal blackFlow diagram:

APPLICATIONRubber industry (90%)Pigment (9%)PlasticsUV protective coatingElectrical conductive agentMARKETAmong top 50 chemicals manufactured in the worldAsia Pacific: largest market in the world (37%)Metallurgy: an emerging application areaGrowth in carbon black market for textile industry

FUTURE TRENDSHybrid fillers to reinforce natural rubberCarbon black filler to alter electrochemical behaviorRecycling of carbon blackSilica and silanes offer challenge to carbon black industry

ENVIRONMENTAL IMPACTOSHA Permissible Exposure Limit- 3.5mg/m3Interacts with cloud, reduces albedo of ice capsLandfill disposal methodPossible carcinogen
