摘要
可再生的氢能源作为化石资源的替代品是一个非常重要的途径,水蒸气催化重整生物质快速裂解获得的液体产物生物油是一种可行的制取可再生氢气的过程。本文介绍了生物油水蒸气催化重整反应机理与热力学分析,介绍了催化重整制氢过程催化剂、制氢工艺条件、代表性的反应器及工艺流程。指出水蒸气催化重整生物油制氢反应的主要约束条件是由于碳的沉积导致的催化剂失活。研究开发具有高活性、高选择性、寿命长、机械强度高容易再生的催化剂与制氢反应器是当前及今后研究的重要方向。
Renewable energy could be an alternative of fossil fuel for hydrogen production. Catalytic steam reforming ofbiomass fast pyrolysis oil is an economically feasible method for hydrogen production. In this paper, some typical reactor designs, process engineering, operation conditions, catalyst, reaction mechanism, and thermal analysis of catalytic steam reforming of bio-oil are presented. The bottleneck of catalytic steam reforming of bio-oil is the catalyst deactivation cased by carbon deposition. Development of a catalyst of high activity, high selectivity, high mechanical strength, long life, and easy regeneration as well as optimized reactor design are the important research directions in the future.
