在利用生物质作为燃料和化学品时，所涉及的关键反应是氢解和使用氢气脱氧。不幸的是，由于各种缺点，例如高成本和与高压操作相关的相当大的危险，分子氢的工业应用受到限制。在这项研究中，提出了一种独特的化学制造工艺，用于使用金属铁和水之间的反应原位产生的氢来诱导生物质碳水化合物的氢解和脱氧。根据所获得的结果，通过金属铁颗粒（氢产生剂）与碳负载的钯催化剂（氢化催化剂）组合原位产生的氢将葡萄糖转化为C3平台化学品，例如丙二醇、羟基丙酮和乳酸。并对反应条件和反应机理进行了探讨。通过使用拟议的系统，通过使用可再生能源（如铁和水反应产生的氢气）从生物质碳水化合物中生产增值化学品，而不完全依赖化石资源。
In the utilization of biomass for fuels and chemicals, the key reactions involved are hydrogenolysis and deoxygenation using hydrogen. Unfortunately, the industrial use of molecular hydrogen is limited because of various drawbacks, such as high cost and considerable hazards associated with high-pressure operation. In this study, a unique chemical manufacturing process was proposed for inducing the hydrogenolysis and deoxygenation of biomass carbohydrates using hydrogen generated in situ from the reaction between metallic iron and water. From the results obtained, hydrogen generated in situ by metallic iron particles (hydrogen-generating agent) combined with a carbon-supported palladium catalyst (hydrogenation catalyst) transforms glucose to C3 platform chemicals, such as propylene glycol, hydroxyacetone, and lactic acid. Moreover, reaction conditions and mechanism were also evaluated. With the use of the proposed system, value-added chemicals were produced from biomass carbohydrates by using renewable sources of energy (such as hydrogen generated from the reaction between iron and water) without the complete dependence on fossil resources.
