A techno-economic model of a solar dry reforming process is used to simulate fifteen case studies in which the reaction is used to produce hydrogen, methanol, and butanal from feedstocks obtained from petrochemical, biogas, landfill gas, flue gas, and direct air capture sources. The goal of this analysis is to provide perspective into the remaining technical challenges associated with the commercial application of a solar-driven dry reforming process, which has great potential to be a building block in the burgeoning global circular economy, as a result of the fact that it consumes two greenhouse gases: carbon dioxide and methane. The average available real-world scale of each feedstock is then used to postulate a minimum catalyst activity that would make the use of these feedstocks competitive with their existing petrochemical alternative. It is found that the majority of the minimum catalyst activities required by each of these applications has been demonstrated in the scientific literature in the past two decades. However, in order for these intrinsic catalytic rates to be practically realisable, significant improvements in photoreactor engineering are required to minimize transport losses and maximize photocatalyst-photon contact.

光催化干重整:这有什么用?

使用太阳能干重整过程的技术经济模型来模拟十五个案例研究,在该案例中,该反应用于从石油化工,沼气,垃圾填埋气,烟道气和直接空气捕获中获得的原料生产氢气,甲醇和丁醛资料来源。该分析的目的是提供与太阳能驱动的干法重整工艺的商业应用相关的剩余技术挑战的视角,由于这一事实,该技术具有成为新兴的全球循环经济的基础的巨大潜力它消耗两种温室气体:二氧化碳和甲烷。然后使用每种原料的平均实际实际使用规模来假定最小的催化剂活性,这将使这些原料的使用与其现有的石化替代品相比具有竞争力。已经发现,在过去的二十年中,这些应用中的每一种所需要的大多数最小催化剂活性已经在科学文献中得到了证明。然而,为了使这些固有的催化速率可在实践中实现,需要在光反应器工程中进行显着改进,以使运输损失最小化并使光催化剂与光子的接触最大化。
