Horse manure, the improper disposal of which, imposes considerable environmental costs, constitutes an apt feedstock for conversion to renewable fuels and chemicals when tail gas reactive pyrolysis (TGRP) is employed. TGRP is a modification of fast pyrolysis that recycles its noncondensable gases and produces a bio-oil low in oxygen concentration and rich in naphthalene. Herein, we evaluate the coproduction of phenol as a value-added renewable chemical, alongside jet-range fuels within distributed TGRP systems using techno-economic analysis and life cycle assessment. We investigate the metrics global warming potential (GWP), cumulative exergy demand (CExD), and cost for the conversion of 200 dry metric tons per day of horse manure to bio-oil and its subsequent upgrade to hydrocarbon fuel and phenolic chemicals. Assigning credits for the offset of the coproducts, the net GWP and CExD of TGRP jet fuel are 10 g of CO2 eq and 0.4 MJ per passenger kilometer distance traveled, respectively. These values are considerably lower than the GWP and CExD of petroleum-based aviation fuel. The minimum fuel selling price of the TGRP jet fuel ($1.35–$1.80 L–1) is estimated to be much greater than that of petroleum-based aviation fuel ($0.42 L–1), except under optimized fuel conversion and coproduct market conditions ($0.53–$0.79 L–1) when including a market price for carbon.

马尾气反应型热解油中的燃料和化学物质:技术经济分析,环境和充满生命的生命周期评估

当采用尾气反应热解法(TGRP)时,对马粪的处理不当会造成相当大的环境成本,它很适合用作转化为可再生燃料和化学物质的原料。TGRP是快速热解的一种改进形式,可循环利用其不可冷凝的气体,并产生氧气浓度低且富含萘的生物油。本文中,我们使用技术经济分析和生命周期评估,评估了苯酚作为增值可再生化学品的联产产品,以及分布式TGRP系统中的射程燃料。我们调查了全球变暖潜能(GWP),累计火用需求(CExD)以及每天将200干燥公吨马粪转化为生物油并随后升级为碳氢燃料和酚类化学品的成本。每乘客公里行驶2 eq和0.4 MJ。这些值大大低于石油基航空燃料的GWP和CExD。TGRP喷气燃料的最低燃料销售价格($ 1.35– $ 1.80 L –1)估计要比石油基航空燃料的最低销售价格($ 0.42 L –1)高得多,除非在最佳燃料转换和副产品市场条件下($ 0.53)。 – $ 0.79 L –1),包括碳的市场价格。
