Recently, sugarcane bagasse was transformed by ketalization reaction into a biocrude with physical-chemical properties adequate for further conversion in typical refining processes. Herein, a representative compound of this biocrude, 1,2:3,5-di-O-isopropylidene-α-D-xylofuranose, DX, in n-hexane was hydro processed in the presence of several palladium-catalysts. Screening in a flow reactor andamong Pd supported on SiO₂, γ-Al₂O₃, HUSY, HY, HBEA and HZSM-5, Pd/HZSM-5 showed the least susceptibility to coke deposition and good deoxygenation capacity, yielding significant amounts of hydrocarbons containing seven or more carbons. Additionally, in a batch and milder conditions, this catalyst was highly selective towards hydrocarbons with high carbon yield and remarkably low coke, i.e., 86 % and <5 % of carbon from DX, respectively. Water was the major product of deoxygenation. The hydrocarbon products included branched and linear alkanes, cycloalkanes and aromatics, whose distribution was sensitive to the catalyst properties, such as support’s mesoporosity.

近来，甘蔗渣通过缩酮化反应被转化为具有天然化学性质的生物原油，其足以在典型的精制过程中进一步转化。在此，在几种钯催化剂的存在下对该生物粗品的代表性化合物，在正己烷中的1,2：3,5-二-O-异亚丙基-α-D-木呋喃糖DX进行加氢处理。在流动反应器的Pd andamong筛选支撑在SiO ₂，γ-Al系₂ ö ₃，HUSY，HY，HBEA和HZSM-5，Pd / HZSM-5对焦炭沉积的敏感性最小，并且具有良好的脱氧能力，可产生大量含七个或更多碳的烃。另外，在间歇和较温和的条件下，该催化剂对具有高碳收率和非常低的焦炭的烃具有高选择性，即分别来自DX的碳的86％和<5％。水是脱氧的主要产物。烃产物包括支链和直链烷烃，环烷烃和芳烃，它们的分布对催化剂性能（例如载体的介孔率）敏感。
