Abstract
Against the backdrop of the advancement of the"dual carbon"strategy and the implementation of the 14th Five-Year Plan,the petrochemical industry is confronted with carbon emission reduction pressures.Biotechnology has emerged as a core pathway for its green transformation.This paper,drawing on the policy orientations of bio-manufacturing both domestically and internationally,systematically examines the integration pathways and practical progress of biotechnology and the petrochemical industry.Diversified breakthroughs have been achieved in the bioconversion of non-grain raw materials:agricultural straw is converted into platform chemicals such as succinic acid through enzymatic hydrolysis and fermentation;the bioconversion of industrial waste gas has reached the industrial demonstration stage;and the technology for microalgae-based carbon sequestration to produce biodiesel is gradually maturing.In terms of process innovation,industrial plants for enzymatic hydrolysis and recycling of PET have been established;microbial oil displacement has increased oil recovery by more than 10 percentage points;and engineered bacterial strains have enabled efficient degradation of petrochemical wastewater.In the field of chemicals and materials,the domestic production of 1,3-propanediol via biological methods has been realized,and bio-based materials such as polylactic acid(PLA)and polyhydroxyalkanoates(PHA)have been applied on a large scale in the agricultural and medical sectors.The conclusion indicates that despite challenges such as insufficient technological maturity and high costs,with the strengthening of policy support and technological iteration,biotechnology will empower the petrochemical industry through the entire chain of raw materials,processes,and products,driving its strategic transformation towards greener raw materials,low-carbon production,and high-value products.关键词
