Abstract

The carboxylic multi-walled carbon nanotube-loaded nickel (Ni/c-MWCNT) catalyst prepared by the excess impregnation method was used for the hydrogenation of oleoresin-based turpentine (OBT) into high energy density fuel. Benefiting from small nickel nanoparticle sizes (about 10 nm) and the carrier’s high surface area, a hydrogenation rate of 99.1% was achieved at 145 °C and 3 MPa, superior to a commercial 5 wt.% Pd/C. Hydrogenated oleoresin-based turpentine (HOBT) satisfied the density, flash point, and freezing point outlined by the American Society of Testing and Materials standard. Hydrogenation improved the oxidative stability, smoke point, and calorific value of OBT while changing its color to water white. The impact of blend ratio on the blended biomass fuel performance was evaluated by measuring the smoke point, density, kinematic viscosity, calorific value, freezing point, and flash point of biofuels blended with HOBT and exo-tetrahydrodicyclopentadiene (JP-10). When HOBT was blended up to 20% (v/v) with JP-10, the performance of blended biomass fuel was comparable to that of JP-10 and even superior at freezing temperatures.

从油基松节油中提取的生物质高能量密度燃料：催化加氢转化以及与化石喷气燃料混合后的特性

采用过量浸渍法制备的羧基多壁碳纳米管负载镍（Ni/c-MWCNT）催化剂被用于将油脂基松节油（OBT）加氢为高能量密度燃料。得益于小尺寸镍纳米颗粒（约 10 纳米）和载体的高表面积，该催化剂在 145 °C 和 3 MPa 条件下的加氢率达到 99.1%，优于 5 wt.% 的商用 Pd/C。氢化油脂基松节油（HOBT）符合美国材料与试验协会标准规定的密度、闪点和凝固点。氢化可提高油基松节油的氧化稳定性、发烟点和热值，同时使其颜色变为水白色。通过测量与 HOBT 和外四氢双环戊二烯（JP-10）混合的生物燃料的烟点、密度、运动粘度、热值、凝固点和闪点，评估了混合比例对混合生物质燃料性能的影响。当 HOBT 与 JP-10 的混合比例达到 20% （v/v）时，混合生物质燃料的性能与 JP-10 相当，在冰点温度下甚至更优。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
