Fumed silica, also known as pyrogenic silica, is an amorphous, synthetic silica produced by vapor phase hydrolysis of chlorosilanes in a hydrogen oxygen flame. In the flame process, primary particles are fused into branched, three-dimensional secondary particles or aggregates. In the collection system, aggregates are mechanically entangled to form agglomerates (Figure 1.). The surface of untreated fumed silica has hydroxyl groups which makes the surface hydrophilic. Fumed…

Gasification is a process that converts organic carbonaceous feedstocks into carbon monoxide, carbon dioxide, and hydrogen by reacting the feedstock at high temperatures (>700°C, 1290°F), without combustion, with a controlled amount of oxygen and/or steam. The Gasification industry can be broken down into several segments, Coal Gasification, Biomass Gasification, etc. Across the world, the major players cover Air Liquide, Siemens, KBR, etc.
