1 What are the environmental issues that need to be addressed urgently in the catalytic cracking units of oil refineries? 2 What are the suitable technologies for flue gas desulfurization in catalytic cracking? Are there any examples of industrial applications? What are the efficiencies of desulfurization, denitrification, and carbon (CO2) removal respectively, and is secondary pollution generated?
