摘 要
生物基化学品因其可再生性和较低的环境影响，逐渐成为替代传统石化产品的理想选择。本研究旨在探讨生物基化学品的生产工艺及其对环境的影响，以期为可持续化学工业提供理论支持和技术参考。研究首先综述了当前生物基化学品的主要生产途径，包括发酵法、酶催化法和热解法等，并分析了各方法的优缺点。随后，通过实验对比不同工艺条件下的产物收率和环境排放数据，发现酶催化法在提高产物收率的同时，显著降低了温室气体排放和水资源消耗。此外，研究还引入了生命周期评估（LCA）方法，系统评估了从原料获取到产品使用的全过程环境影响。结果表明，优化后的酶催化工艺在减少碳足迹和资源消耗方面具有显著优势。本研究的贡献在于提出了基于酶催化的生物基化学品高效生产工艺，并通过LCA方法量化了其环境效益，为推动绿色化学工业的发展提供了科学依据。

Abstract
Bio-based chemicals have gradually become ideal alternatives to traditional petrochemical products because of their renewability and low environmental impact. The purpose of this study is to investigate the production process of bio-based chemicals and their environmental impact in order to provide theoretical support and technical reference for the sustainable chemical industry. The study first reviewed the main production routes of current bio-based chemicals, including fermentation, enzyme catalysis and pyrolysis, and analyzed the advantages and disadvantages of each method. Subsequently, by comparing the product yield and environmental emission data under different process conditions, it was found that the enzyme catalysis method improves the product yield and significantly reduces the greenhouse gas emission and water consumption. In addition, the Life Cycle Assessment (LCA) approach was introduced to systematically assess the overall environmental impact from raw material acquisition to product use. The results show that the optimized enzyme catalytic process has significant advantages in reducing carbon footprint and resource consumption. The contribution of this study is to propose the efficient production process of bio-based chemicals based on enzyme catalysis and quantify the environmental benefits by LCA method, which provides a scientific basis for promoting the development of green chemical industry.
