In the present study, a new and novel attempt was made to investigate the effect of liquefaction (20–60%) on energy efficient gaseous biofuel recovery and cost during chemo thermo disperser liquefaction of food waste (CTDL). The outcome of the study revealed that rpm (10,000), specific energy input (174 kJ/kg TS), disintegration time (5 min) and energy efficiency of about 11.1 kg SCOD/KWh were considered as optimum in terms of energy and cost. The cost incurred to achieve 20–40% liquefaction was estimated to be 0.0132–0.0168 USD and found to be comparatively very low than the cost incurred (0.0367–0.0547) to achieve 50–60% liquefaction. The biodegradability results showed that a significant increment in biodegradability was achieved (from 0.26 gCOD/gCOD to 0.8 gCOD/gCOD) when the liquefaction was increased from 30 to 40% and an insignificant increment in biodegradability (from 0.8 gCOD/gCOD to 0.84 gCOD/gCOD) was achieved when the liquefaction was increased from 40 to 60%, respectively. The impact of liquefaction on energy balance and cost at tonnage level revealed that 40% liquefaction was considered to be profitable with energy ratio and net profit of about 1.12 and 93 USD/Ton, respectively.

在本研究中，人们进行了一项新的新颖尝试来研究液化（20-60％）对食物垃圾化学热分散器液化（CTDL）过程中节能的气态生物燃料回收和成本的影响。研究结果表明，就能量和成本而言，转速（10,000），比能量输入（174 kJ / kg TS），崩解时间（5分钟）和约11.1 kg SCOD / KWh的能量效率被认为是最佳的。实现20–40％的液化的成本估计为0.0132–0.0168 USD，发现比实现50–60％的液化的成本（0.0367–0.0547）低得多。生物降解性结果表明，生物降解性得到了显着提高（从0.26 gCOD / gCOD降低至0。当液化率从30％增加到40％时，可生物降解性的增加不明显（从0.8 gCOD / gCOD增加到0.84 gCOD / gCOD）；当液化率从30％增加到40％时，可生物降解性增加不明显（从0.8 gCOD / gCOD增加到0.84 gCOD / gCOD）。液化对能源平衡和吨位成本的影响表明，液化被认为是有利可图的，能量比和净利润分别约为1.12美元/吨和93美元/吨。
