Abstract This article aims at investigating the oxygen-steam gasification of Karanja press seed cake using experimental and modeling studies and compare the results of these studies with those for other feedstocks such as rice husk, sawdust, and sunflower husk. The experimental work was conducted in a fixed bed reactor and the process simulation model was created in ASPEN Plus. Finally, validation and benchmarking exercise were conducted by validating the ASPEN Plus model using experimental results. A general agreement was found between the experimental results and ASPEN Plus process model results with a maximum variation of ±4%. Furthermore, sensitivity analyses were carried out to understand the effects of parameters such as gasification temperature, ER (equivalence ratio), and SBR (steam to biomass ratio) on synthesis gas composition, LHV (lower heating value) and CGE (cold gas efficiency). The optimal values of ER and SBR in this study were found to be 0.23 and 0.3, respectively. The CGE was found to increase with an increase in the temperature. Values of CGE and LHV were found to be as high as 95% and ∼12 MJ/Nm3, respectively at 1000 °C for all feedstocks. The optimum SBR value was found to vary from 0.3 to 0.7 for H2/CO variation in the range of ∼0.83-1.0.
