Fluidized bed gasifiers utilizing biomass or coal, with silica sand as a bed material, typically work with superficial velocities in the range of 1 m·s −1 to 4 m·s −1.The sand is used in the gasifier as an inert material to facilitate the fluidization of biomass or coal and acts as a heat transfer medium in the fluidized bed reactor.
The characteristic of CEN Standard Sand is its specific grain size distribution. It ranges between 0.08 and 2.00 mm. The grain size distribution is drawn in the picture (cumulated sieve residue in % vs squared mesh size in mm) and listed in the table below. The maximum moisture content is 0.2%. The sand is portioned in bags of 1,350 (± 5) g.

About Silica Sand. Silica Sand contains at least 95% SiO2 and less than 0.6% iron oxide. The most common form of SiO2 is quartz, which is mined from hard rock deposits. It is chemically inert and is often white/colorless. However, the color of each sand deposit depends on the variety of minerals and rock detritus that make up the deposit.
Silica sand is often used in industrial processes, such as making glass and concrete, due to its high silica content and uniform grain size. A2A! Normal sand is not Silica sand. Though normal sand composition consists of silica (Si02) it is not silica.
