Process of promoting chemical reactions

Patent ·
OSTI ID:6742212
This patent describes a process of promoting chemical reactions between gasiform reactant substances and finely divided solid combustible materials, such as finely divided mineral solid fuels, and coke. The process consists of passing a gasiform fluid stream upwardly through a deep substantially stationary mass of small-size noncombustible refractory solids which are of larger size than comminuted solid fuel. The solids are initially uniformly sized, being smaller than about 1/2-inch but larger than about 1/16-inch mean diameter. These solids are confined as a deep bed in a generator at an elevated temperature adapted to promote reaction of said fuel with said reactant. This occurs at such a velocity that said refractory solids are substantially densely fluidized and substantially continuously retained in said bed substantially in ebullient motion in said generator. This causes said reaction to occur with complete consumption of said fuel in said stream in said generator as said stream passes by a mobile tortuous path upwardly through the bed while hindering the passage of said solid fuel particles through said bed. The gaseous reaction products are then removed from said generator in said stream.
