Iron oxide can be reduced by CO and H ₂ . Blast furnace is historically important as it provided iron in reasonably pure form. In Blast furnace, coke and hot air is used with iron oxide. Syngas is manufactured by the reaction of carbonaceous matter with water at high temperature. It has application in Blast furnace. In context of this process, the correct statement(s) is/are

Options

  1. AUse of syngas helps in reducing the slag.
  2. BSyngas on reaction with water produces better reducing agent.
  3. CCarbon itself acts as the main reducing agent in blast furnance.
  4. DUse of syngas eliminates the chances of pig iron formation.
