Abstract. This work analyses the effect in the syngas composition of blending feedstocks during biomass gasification tests. A lab-scale gasifier with a biomass-batch capacity of around 500 g is used for these tests. Pre-heated air functions as the carrier gas throughout all configurations, while gas chromatography (GC) is used to analyze the composition of the product gas. By accounting for low-density feedstock, such as cotton stalk, which is common in the North San Joaquin Valley, NSJV, options for repurposing this waste are explored. Incorporating these types of feedstocks in co-processing gasification could provide a feasible alternative for producing heat/electric power and byproducts such as biochar. Biochar is a versatile material, that can be used for soil amendment, filtration, and other agricultural or industrial applications. Addressing this aspect enables biomass waste to contribute more effectively and at a larger scale to the circular bioeconomy.
The main contribution of this paper is the confirmation of the potential for addressing fuel flexibility limitations commonly encountered in biomass gasification, with a focus on the NSJV. This area of work not only provides a sustainable way to process agriculture and forest biomass waste, but it also reduces air-pollution in disadvantaged areas of the country that already experience a high level of respiratory diseases.
