New technologies for products development in petrochemical industrial chain were introduced,such as molecular designing,combinatorial chemistry,nanometer and microemulsion,biofermentation,and so on.Taking the environmental friendly utilizing technology of carbon dioxide as example,it is proposed to develop environmental friendly chemical industrial chain,take full use of the existing leading technologies to combine emission reduction of carbon dioxide and environmental friendly development of petrochemical products chain,increase the added value of products,reduce consumption rate of energy source and resources,so as to eradicate or greatly reduce pollution of the three wastes.
