The Preparation Process Optimization of the New SAPO-34 Catalyst and Its Catalytic Performance Evaluation on the Regulation of the Distribution of Biomass Pyrolysis Products

能源是人类赖以生存的物质基础,环境是社会发展的前提条件。我国作为世界上能源消费大国之一,大量化石能源的消耗造成我国能源储备日益匮乏,以及由于人们过度消费所导致的生态破坏和环境污染范围逐步扩大。能源短缺和环境污染已成为21世纪人类发展面临的两大难题,其造成的各类问题也日益成为人们关注的焦点。生物质能源作为一种分布广泛的自然资源,有着广阔的研究前景。低碳烯烃作为石油化工需求最大,用途最广的基本原料,在化工行业扮演着举足轻重的角色。基于调控生物质热解产物分布,高效合成低碳烯烃的目的,本实验计划通过有机结合生物质催化热解技术和SAPO-34分子筛高效催化的优势,拟围绕①生物质催化热解制气过程的催化调控机理;②生物质催化热解产物中生物质油的改性、精炼工艺;③SAPO-34分子筛催化剂的合成、表征及工艺优化;④以低碳烯烃的选择性和产率为技术指标来进行热解气催化制烯烃应用特性考察和工艺参数优化为关键科学问题,进行深入、系统的研究,以期获得生物质资源化、高效化利用的基础数据。

Energy is the material basis of human existence,and environment is the precondition of social development.As one of the largest energy consumers in the world,China’s energy reserves are increasingly depleted due to the consumption of a large number of fossil fuels,and the ecological damage and environmental pollution caused by excessive consumption are gradually expanding.Energy shortage and environmental pollution have become two major problems facing human development in the 21st century.As the basic raw materials with the largest demand and the most widely used in petrochemical industry,low-carbon olefins play an important role in the chemical industry.Based on the purpose of regulating the distribution of biomass pyrolysis products and the efficient synthesis of low carbon olefins,this experiment plans to focus on①the catalytic control mechanism of biomass catalytic pyrolysis gas production process by organically combining the advantages of catalytic pyrolysis technology of biomass and efficient catalysis of SAPO-34 molecular sieve;②modification and refining of biomass oil in catalytic pyrolysis products of biomass;③Synthesis,characterization and process optimization of SAPO-34 molecular sieve catalyst;④the selectivity and yield of low carbon olefin as technical indicators to conduct pyrolysis gas catalytic olefin production application characteristics investigation and process parameters optimization as a key scientific problem,in-depth,systematic research,in order to obtain biomass resources,efficient utilization of the basic data.
