Q5 Synthesis gas may be prepared by a continuous, noncatalytic conversion of any
hydrocarbon by means of controlled partial combustion in a fire-brick lined reactor. In the basic
form of this process, the hydrocarbon and oxidant (oxygen or air) are separately preheated and
charged to the reactor. Before entering the reaction zone, the two feed stocks are intimately mixed
in a combustion chamber. The heat produced by combustion of part of the hydrocarbon pyrolyzes
the remaining hydrocarbons into gas and a small amount of carbon in the reaction zone. The reactor
effluent then passes through a waste-heat boiler, a water-wash carbon-removal unit, and a water
cooler-scrubber. Carbon is recovered in equipment of simple design in a form which can be used
as fuel or in ordinary carbon products. Prepare a simplified flow sheet for the process, with
temperatures and pressure conditions at each piece of equipment. Note that standard symbols
should be used for all equipment.
