Studies of co-processing catalytic fast pyrolysis (CFP) oil with vacuum gas oil (VGO) are conducted in a Davison Circulating Riser (DCR). The CFP oil (CFPO) for this study was produced by upgrading fast-pyrolysis vapors from pine in an ex-situ fixed-bed reactor. CFPOs were co-processed at up to a volume fraction of 0.05 with VGO at 521 °C and 257 kPa. The yields of oil, aqueous phase, tail gas, and coke were measured. The amount of coke was determined from the carbon containing components in the regenerator flue gas. A compositional analysis was conducted with gas chromatography and elemental analyzers. The organic liquids were distilled into gasoline, jet-fuel, diesel, and resid fractions. A biocarbon analysis was conducted on the organic phase and its individual boiling-point fractions. The results show a small decrease in liquid yield and a generally increased gas yield when co-processing CFPO with VGO. The experiments showed that 75%–100% of biocarbon is incorporated into liquid fuels relative to fossil carbon, depending on catalyst and CFPO. The measurements indicate that cracked CFPO components are predominantly included in the jet-fuel and diesel fractions. A techno-economic analysis (TEA) estimated the minimum fuel selling price (MSFP) for fuel-range products derived from FCC co-processing of CFPO at 24 to 29 $/GJ ($2.90 to $3.50 per gasoline-gallon equivalent; GGE) at a yield of 4.87–7.14 GJ/t(biomass) or 40–58 GGE/t.

在戴维森循环提升管 (DCR) 中进行协同处理催化快速裂解 (CFP) 油与真空瓦斯油 (VGO) 的研究。用于本研究的 CFP 油 (CFPO) 是通过在异地固定床反应器中升级松木的快速热解蒸气而生产的。CFPO 与 VGO 在 521 °C 和 257 kPa 下以高达 0.05 的体积分数进行共处理。测量油、水相、尾气和焦炭的产率。焦炭的量由再生器烟道气中的含碳组分确定。使用气相色谱和元素分析仪进行成分分析。有机液体被蒸馏成汽油、喷气燃料、柴油和渣油馏分。对有机相及其各个沸点馏分进行了生物碳分析。结果表明，当 CFPO 与 VGO 共处理时，液体产率略有下降，而气体产率普遍增加。实验表明，相对于化石碳，75%–100% 的生物碳被掺入液体燃料中，具体取决于催化剂和 CFPO。测量结果表明，裂解的 CFPO 组分主要包含在喷气燃料和柴油馏分中。一项技术经济分析 (TEA) 估计，来自 CFPO 的 FCC 协同处理的燃料范围产品的最低燃料销售价格 (MSFP) 为 24 至 29 美元/GJ（每加仑汽油当量 2.90 至 3.50 美元；GGE）产量为 4.87–7.14 GJ/t（生物质）或 40–58 GGE/t。测量结果表明，裂解的 CFPO 组分主要包含在喷气燃料和柴油馏分中。一项技术经济分析 (TEA) 估计，来自 CFPO 的 FCC 协同处理的燃料范围产品的最低燃料销售价格 (MSFP) 为 24 至 29 美元/GJ（每加仑汽油当量 2.90 至 3.50 美元；GGE）产量为 4.87–7.14 GJ/t（生物质）或 40–58 GGE/t。测量结果表明，裂解的 CFPO 组分主要包含在喷气燃料和柴油馏分中。一项技术经济分析 (TEA) 估计，来自 CFPO 的 FCC 协同处理的燃料范围产品的最低燃料销售价格 (MSFP) 为 24 至 29 美元/GJ（每加仑汽油当量 2.90 至 3.50 美元；GGE）产量为 4.87–7.14 GJ/t（生物质）或 40–58 GGE/t。
