Air-steam and oxy-steam gasification of hydrolytic residues from biorefinery

Experimental study into the influence of straw content in fuel on parameters of generator gas

“…To this end, activities in the field of development and improvement of the gasifier design have appeared [8][9][10][11][12]. Operation parameters consistent with the design and physical and chemical properties of fuel were established [4,14,[17][18][19]. Gasification of fuel mixtures on the basis of wood, coal, high-ash sediments of sewage with addition of straw was studied [14,17,19].…”

“…Operation parameters consistent with the design and physical and chemical properties of fuel were established [4,14,[17][18][19]. Gasification of fuel mixtures on the basis of wood, coal, high-ash sediments of sewage with addition of straw was studied [14,17,19]. It was stated in the above studies that the advantage of gasification of straw containing fuel mixtures consists in the ability of straw to emit a significant amount of heat in a small period of time.…”

“…In gasification of straw and wood fuel mixtures, there is a negative phenomenon as well, e. g. high resin content in the produced gas because of high content of resin in wood, especially coniferous species [8,17]. There were attempts to solve the problem by designing the gasification chamber tuyere belt (tuyeres, pipes, air distribution boxes) and an additional thermal insulation of the hopper which provides temperature in the active zone within 1,100-1,400 °С [8,12,[20][21][22].…”

“…Efficiency of the process of producing gas from straw-containing fuels is also improved by selecting conditions of air supply to the gas-forming chamber [14, [17][18][19]. Steam-oxygen blast at normal and high pressures [17], oxygen enriched air blowing [19] and vapor-air gasification [18] are widely used.…”

An Assessment of Operating Conditions for Supercritical Water Gasification and Safety Issues

“…In addition, it has to be considered that the extensive usage of energy cultivations is producing depletion of the soil with loss of nutrients and inorganic compounds, which are utilized during the photosynthetic process. Despite woody biomass is still the most diffused source of feedstock in thermochemical conversion processes, there is a great attention worldwide on residual biomasses [3][4][5].…”
