CO2 gasification of coal cokes using internally circulating fluidized bed reactor by concentrated Xe-light irradiation for solar gasification

Analysis of Solar Steam Gasification of Carbon- Rich Fly Ash to Produce Synthetic Gas.

“…This heat transfer limitation of the bed was responsible for low performance of the solar fluidized bed reactor. To overcome this problem, the group has proposed the concept of an internally circulating fluidized bed reactor (12)(13)(14).…”

Design and demonstration of a prototype 1.5 kWth hybrid solar/autothermal steam gasifier

“…Prominent solar-driven gasifier designs that have been examined in literature have employed entrained flow [11,16,18], drop tubes [7,8,10], packed beds [15,19,20], and fluidized beds [12,[21][22][23][24][25][26][27][28]. Entrained-flow and drop-tube gasifiers generally have very short residence times while benefiting from enhanced heat and mass transfer.…”

“…Directly-irradiated fluidized beds for http://dx.doi.org/10.1016/j.fuel.2017.09.059solar gasification of coal, cokes, and cellulose have been explored in literature [12,[21][22][23][24][25][26][27][28]. One drawback of fluidized-bed designs compared to packed beds is that small, relatively uniform feedstock particles are required, translating to costlier feedstock preparation.…”

Cold test with a benchtop set-up for fluidized bed reactor using quartz sand to simulate gasification of coal cokes by concentrated solar radiation

“…The present authors (Niigata University, Japan) developed "fluidized bed reactor" containing coke particles for thermochemical solar gasification with steam and CO 2 [10][11][12][13]. Recently, quartz sand was employed as a chemically-inert bed material for the fluidized bed and as a thermal transfer/storage medium inside the reactor for coke gasification under direct light irradiation.…”
