6. A homogeneous and stable mixture formed when one or several substances are dispersed in another substance is called a (solution); the substance that is dissolved is called the (solute), while the substance that dissolves other substances is called the (solvent). 7. The petrochemical industry refers to the chemical industry that uses (petroleum) and (natural gas) as raw materials. 8. The reaction equation for steam-air charring is (C + O2 = CO2 + Q). 9. The functions of the waste heat boiler in the pyrolysis furnace are, first, (recovering thermal energy) and second, (reducing the emission temperature). 10. The chemical added to the boiler feed water is (sodium carbonate), whose molecular formula is (Na2CO3).

The functions of the waste heat boiler in the pyrolysis furnace are, first, to cool the pyrolysis gas and reduce secondary reactions, and second, to recover the heat from the pyrolysis gas. 10. The chemical added to the boiler feed water is (sodium phosphate), with the molecular formula (Na3PO4*12H2O).
We can discuss the differences. I’m a beginner and am learning slowly*.
