In the last decade, much of the research was focused towards bio refining, mainly due to increased greenhouse gasses arising from the use of the non-renewable resources. Since biomass contains more oxygen than hydrocarbons, catalytic hydrogenation and/or hydro-deoxygenation may be used to remove oxygen from derived bio-oils to improve their stability and enhance their properties. Hydrogen solubility in oxygenated compounds as well as in solvents is crucial in performing reactions, due to its influences on the reaction rates, catalyst activity and selectivity. In the present work hydrogen solubility in two bio-based components, guaiacol and levulinic acid, the latter with an addition of 10 wt% of water, in the temperature range from 322 K up to 422 K and pressures up to 20 MPa was investigated. A high-pressure equilibrium cell using an analytical isothermal method was applied. The solubility data was correlated using the Soave-Redlich-Kwong (SRK), Peng–Robinson–Boston–Mathias (PR–BM) and perturbed chain statistical associating fluid theory (PC–SAFT) equations of state (EOS).

在过去十年中，大部分研究都集中在生物精炼上，主要是由于使用不可再生资源导致温室气体增加。由于生物质比碳氢化合物含有更多的氧，催化氢化和/或加氢脱氧可用于从衍生的生物油中去除氧以提高它们的稳定性并增强它们的特性。由于氢对反应速率、催化剂活性和选择性的影响，氢在含氧化合物和溶剂中的溶解度对于进行反应至关重要。在目前的工作中，研究了氢在两种生物基成分愈创木酚和乙酰丙酸中的溶解度，后者添加了 10 wt% 的水，温度范围为 322 K 至 422 K，压力高达 20 MPa。应用了使用分析等温方法的高压平衡池。溶解度数据使用 Soave-Redlich-Kwong (SRK)、Peng-Robinson-Boston-Mathias (PR-BM) 和扰动链统计相关流体理论 (PC-SAFT) 状态方程 (EOS) 相关联。
