据美国《化学工程》美国太平洋西北国家实验室(PNNL)开发了利用海藻生产原油的连续生产新工艺。这种新工艺是水热液化和催化水热气化的组合工艺,把海藻浆液加热到350℃并加压到20.68 MPa,能够降低用海藻生产原油的生产成本。研究所用的反应器能把海藻中50%~70%的碳转化为原油。除了生产能炼制得到航空煤油、汽油和柴油的原油外,还产生燃料气以及海藻繁殖所需的水、氮、磷、钾等营养成份。高压系统的投资相对较高,但由于不需用溶剂萃取油和海藻干燥的高耗 According to the US “Chemical Engineering” Pacific Northwest National Laboratory (PNNL) has developed a continuous production of new technology using crude oil produced by seaweed. The new process is a combination of hydrothermal liquefaction and catalytic hydrothermal gasification. Heating the seaweed slurry to 350 ° C and pressurizing to 20.68 MPa can reduce the cost of producing crude oil from seaweed. The reactor used in the study was able to convert 50% to 70% of the carbon in seaweeds to crude oil. In addition to producing crude oil that can be refined to produce aviation kerosene, gasoline and diesel fuel, it also produces nutrients such as water, nitrogen, phosphorus and potassium for fuel gas and seaweed breeding. High-pressure system investment is relatively high, but because of the need to use solvent extraction of oil and seaweed dry high consumption
