Non-catalytic hydropyrolysis of Chlorella pyrenoidosa was studied by using a stainless-steel batch reactor at different temperature (150-450 °C), time (5-120 min) and initial hydrogen pressure (1 atm-8 MPa), aiming to find how these parameters affect the product (oil, gas and solid) yields and properties of the hydropyrolysis oil (HPO). Temperature was the most influential factor to the relative amount of each product and properties of the HPOs. The hydrogen favored the stabilization of the active intermediates but cannot guarantee to produce HPOs in higher hydrogen at its higher initial pressure. The HPO, which showed much difference in component strongly depending on the reaction conditions, mainly consisted of aromatics and straight-chain hydrocarbons, amides, amines, nitriles and carboxylic acids at moderate temperatures. The main gas products detected during the hydropyrolysis were unreacted H2, CO2, CO and CH4. About 85% of energy originally present in the microalgae was recovered as oil under the optimal conditions.
微藻角毛藻的非催化加氢热解研究采用不锈钢间歇式反应器，在不同温度（150-450°C）、时间（5-120min）和初始氢压（1atm-8MPa）下进行，旨在探讨这些参数如何影响产物（油、气和固）产率和加氢热解油（HPO）的性质。温度对各产物的相对含量和 HPO 的性质影响最大。氢气有利于活性中间体的稳定，但不能保证在较高初始压力下产生 HPO。HPO 的成分差异很大，强烈依赖于反应条件，主要由芳烃和直链烃、酰胺、胺、腈和羧酸组成，在中等温度下。加氢热解过程中检测到的主要气体产物是未反应的 H2、CO2、CO 和 CH4。在最佳条件下，约 85%的微藻中原始存在的能量以油的形式回收。
