| 摘要： | One factor limiting the development of commercial biomass pyrolysis is challenges related to the transportation of the produced pyrolysis oil. The oil has different chemical and physical properties than crude oil, including more water and oxygen and has lower H/C ratio, higher specific gravity and density, higher acidity, and lower energy content. These differences could limit its ability to be transported by existing petroleum pipelines. Pyrolysis oil can also be treated, normally by catalytic hydrodeoxygenation, and approaches crude oil and petroleum condensates at higher severity levels. This improvement also results in lower liquid yield and high hydrogen consumption. Biomass resources for pyrolysis are expected to become plentiful and widely distributed in the future, mainly through the use of crop residuals and growing of energy crops such as perennial grasses, annual grasses, and woody crops. Crude oil pipelines are less well distributed and, when evaluated on a county level, could access about 18% of the total biomass supply. States with high potential include Texas, Oklahoma, California, and Louisiana. In this study, published data on pyrolysis oil was compiled into a data set along with bio-source source material, pyrolysis reactor conditions, and upgrading conditions for comparison to typical crude oils. Data of this type is expected to be useful in understanding the properties and chemistry and shipment of pyrolysis oil to refineries, where it can be further processed to fuel or used as a source of process heat. |
