Preliminary Study on Impact of Disruptive Technologies in Chemical, Metallurgical, and Material Fields

The Research Group of Chemical, Metallurgical, and Material Fields

Strategic Study of CAE 2018, Volume 20, Issue 6,   Pages 34-41 doi: 10.15302/J-SSCAE-2018.06.006

Abstract:

The chemical, metallurgical and material industries re-process natural resources to produce materials, chemicals, and secondary energies necessary for human life, thereby providing an important material basis for social development and economic construction. This paper reviews the recognized disruptive technologies in the history of chemical, metallurgical, and material industries, and analyzes the impact of such technologies on people's daily lives, the progress of human society, and the disruption of traditional technologies. According to vision driving, problem orientation, and the world technology development trend, we forecast the future sustainable science development models, which are efficient, safe, energy-saving, and environment-friendly, in the chemical, metallurgical, and material industries, and predict the impacts of possible disruptive technologies on national economy and people’s livelihood. The slurry bed hydro-conversion technology, the metallurgical manufacturing process function expansion technology, grapheme, and other disruptive technologies are proposed. Finally, relevant policies and suggestions are put forward for the cultivation, development, and environment of disruptive technologies.
