Dataset on Experimental investigation and comparative assessment study of biofuel Yield and characteristics obtained through catalyzed and uncatalyzed transesterification of Flax seed oil (Linum usitatissimum)

These research work data were obtained from the experimental investigation and comparative assessment study of biofuel Yield and characteristics obtained through non-Catalyzed, Super Critical Ethanol, homogeneous, heterogeneous and bio-catalytic (Enzymatic) transesterification of Flax seed oil (Linum usitatissimum) in Diverse Green Fuel Applications. The effects of various catalytic, non-catalytic and supercritical alcohol transesterification process on biodiesel physical properties such as density, kinematic viscosity, flash point temperature, cloud point and pour point were evaluated under American petroleum institute (API), ASTM D 6751-07b and the European union (EN 14214) recommended standard procedures and techniques. Similarly, these standard procedures were also employed to assess the chemical characteristics of the synthesized flaxseed oil biofuel such as acid number, oxidation stability, saponification number, iodine value, cetane index, biofuel calorific value, copper strip corrosion and percentages of sulphated ash, carbon residue, total and free glycerin, water and sediment among others. Reasonable consideration on the importance of repeatability in data accuracy and precision was observed in the course of the experiment.

本研究数据集源自针对亚麻籽油（Linum usitatissimum）经非催化、超临界乙醇、均相、非均相及生物催化（酶法，Enzymatic）酯交换反应制备的生物燃料产率与特性开展的实验探究与对比评价研究，涵盖各类绿色燃料应用场景。本研究依据美国石油学会（American Petroleum Institute, API）、ASTM D 6751-07b及欧盟（European Union, EN 14214）推荐的标准流程与测试方法，评估了各类催化、非催化及超临界醇酯交换工艺对生物柴油物理性能的影响，包括密度、运动粘度、闪点、浊点与倾点。同理，本研究采用上述标准流程，对合成亚麻籽油生物燃料的化学特性进行测评，涵盖酸值、氧化安定性、皂化值、碘值、十六烷指数、生物燃料热值、铜片腐蚀，以及硫酸盐灰分、残炭、总甘油与游离甘油含量、水分与沉淀物占比等指标。实验过程中充分考量了重复性对数据准确性与精密度的重要性。
