Preparation of Biomass Mixtures with Residual Oil for Gasification to Produce Synthesis Gas

The effect of the preparation of raw materials (aqueous suspensions of the mixtures of biomass and oil residues) for gasification on the results of gasification and the composition and properties of the resulting synthesis gas was studied. It was found that combined mechanical activation of the suspensions/emulsions of oil and vegetable raw materials makes it possible to obtain synthesis gas with a high ratio of H-2 : CO = 1.9-2.3 and a low soot content upon gasification. Synthesis gas can be separated and used for catalytic conversion into valuable organic products. The features of the preparation of homogeneous highly dispersed suspensions by mixing biomass and oil residues, in particular, a synergistic effect upon mixing biomass and oil raw materials, were revealed.
