The variation of YFAME with the nM/nO ratio in the RPB system is shown in Table 2. The nM/nO ratio is adjusted by the QML, while the QOL is maintained at a constant 181 ml/min. When the nM/nO ratio
is elevated from 4 to 6, YFAME increases from 58.6% to 64.8% as a result of the shift in the chemical equilibrium toward the products of the transesterification reaction.
