Syngas from catalytic steam reforming of palm oil mill effluent: An optimization study

In this work, the syngas production rate (FSyngas) of LaNiO3-catalysed steam reforming of palm oil mill effluent (POME) was optimized with respect to POME flow rate ( _VPOME), catalyst weight (Wcat), and particle size (dcat). With a net acidity, the synthesized LaNiO3 catalysed POME steam reforming...
