本报告记录了美国国家可再生能源实验室（NREL）对利用2000干公吨/天（2205美吨/天）生物质燃料设施的合成气通过甲醇制汽油路线制造汽油的可行性的评估。在为NREL的热化学乙醇设计报告（Phillips et al. 2007）开发的模型的基础上，在Aspen Plus中为本研究开发了一个新的技术经济模型。将必要的工艺变化纳入生物质制汽油模型，使用甲醇合成操作，然后转换，升级和精加工为汽油。采用类似于以前NREL设计报告中使用的方法，原料成本为50.70美元/干吨（55.89美元/干吨），通过木材气化、甲醇合成和甲醇制汽油的生物质生产的汽油和液化石油气（LPG）的估计工厂出厂价格为16.60美元/百万英热（15.73美元/吉焦）（2007年美元）。汽油和液化石油气的相应单价分别为1.95美元/加仑（0.52美元/升）和1.53美元/加仑（0.40美元/升），每美吨干生物质的产量分别为55.1加仑和9.3加仑（每公吨干生物质的产量分别为229.9和38.8升）。
This report documents the National Renewable Energy Laboratory's (NREL's) assessment of the feasibility of making gasoline via the methanol-to-gasoline route using syngas from a 2,000 dry metric tonne/day (2,205 U.S. ton/day) biomass-fed facility. A new technoeconomic model was developed in Aspen Plus for this study, based on the model developed for NREL's thermochemical ethanol design report (Phillips et al. 2007). The necessary process changes were incorporated into a biomass-to-gasoline model using a methanol synthesis operation followed by conversion, upgrading, and finishing to gasoline. Using a methodology similar to that used in previous NREL design reports and a feedstock cost of $50.70/dry ton ($55.89/dry metric tonne), the estimated plant gate price is $16.60/MMBtu ($15.73/GJ) (U.S. $2007) for gasoline and liquefied petroleum gas (LPG) produced from biomass via gasification of wood, methanol synthesis, and the methanol-to-gasoline process. The corresponding unit prices for gasoline and LPG are $1.95/gallon ($0.52/liter) and $1.53/gallon ($0.40/liter) with yields of 55.1 and 9.3 gallons per U.S. ton of dry biomass (229.9 and 38.8 liters per metric tonne of dry biomass), respectively.
