摘要

作者在180°C、200°C和220°C的温度下，在70、80和90 bar的最终反应器压力值下，研究了浮萍水生生物质和氢供体溶剂甲醇的加氢液化。在所有反应温度下，反应器压力的升高导致生物原油产量的增加，最高热值为22.19 MJ/kg，而生物炭也描述了其用于各种应用和作为生物炼制原料的潜力。傅里叶变换红外光谱和气相色谱质谱分析表明，生物原油中存在酯类、长链烷烃、醚类、酚类等。这项工作的主要发现表明，目前的生物原油(不含任何催化剂)的燃料性能优于在550℃热解温度下从类似生物质中获得的非催化和氢催化生物油。

Hydro-liquefaction of Lemna minor (Duckweed) with hydrogen-donor solvent at varying hydrogen pressures

ABSTRACT The authors have investigated hydro-liquefaction of Lemna minor (duckweed) aquatic biomass and a hydrogen-donor solvent, methanol, at temperatures of 180 °C, 200 °C and 220 °C and final reactor pressure values of 70, 80 and 90 bar. The rise in reactor pressure for all reaction temperatures led to an increase in biocrude yield with a maximum higher heating value of 22.19 MJ/kg, while the biochar also depicted its potential to be used in varied applications and as a bio-refinery feedstock. Fourier Transform Infrared Spectroscopy and Gas Chromatography Mass Spectrometry analysis of biocrude indicated the presence of esters and long chain alkanes, ethers, phenols, etc. The main finding of this work disclosed that fuel properties of the present biocrude (without any catalyst) were better than their non-catalytic and hydro-catalytic bio-oil counterparts obtained from similar biomass at a pyrolysis temperature of 550 °C.

期刊介绍： Engineering and sustainable development are intrinsically linked. All capital plant and every consumable product depends on an engineering input through design, manufacture and operation, if not for the product itself then for the equipment required to process and transport the raw materials and the final product. Many aspects of sustainable development depend directly on appropriate and timely actions by engineers. Engineering is an extended process of analysis, synthesis, evaluation and execution and, therefore, it is argued that engineers must be involved from the outset of any proposal to develop sustainable solutions. Engineering embraces many disciplines and truly sustainable solutions are usually inter-disciplinary in nature.
