本文研究了使用太阳能熔盐（60wt% NaNO3 和 40wt% KNO3）的二元混合物作为传热介质，通过生物质的热化学转化生产太阳能燃料。热化学转化可以是通过硝酸盐熔盐和生物质直接接触将多余的太阳辐射转化为可储存的化学燃料的途径。传统的固定床热解和熔盐热解是在惰性气氛下、500℃的温度下进行的。分析了永久气体和产生的生物油的成分以及反应器内的温度分布。观察到两种独特的途径：传统固定床热解的吸热过程和熔盐热解的放热过程。已尝试找出造成这种差异的可能原因。
The use of a binary mixture of solar molten salts (60 wt% NaNO3and 40 wt% KNO3) as a heat transfer medium for the production of a solar fuel by the thermochemical conversion of biomass is investigated in the present paper. Thermochemical conversion can be a route for converting the surplus solar irradiation via the direct contact of nitrate molten salts and biomass into storable chemical fuel. Traditional fixed-bed pyrolysis and molten salts pyrolysis have been carried out under an inert atmosphere at a temperature of 500 °C. The composition of the permanent gases and the bio-oil produced has been analyzed along with the temperature profiles inside the reactor. Two distinctive pathways have been observed: an endothermic process in the case of traditional fixed-bed pyrolysis and an exothermic process in the case of molten salt pyrolysis. An attempt has been made to identify possible causes for such differences.
