Processes Operated in Packed Bed Reactors PBRs

Catal3dic processes are carried out in several types of reactors like fixed bed, moving bed, trickle bed, two- and three phase fluidized beds, bubble columns, and stirred tanks. Examples of important fixed bed catal3dic processes with only one fluid phase are given in Table 11.1. Other fixed bed processes with particular catalyst designs exist as well. 

Several packed bed reactors are employed by the petroleum refining industries utilizing natural gas as feedstock. Different compositions of synthesis gas (mixtures of carbon monoxide and hydrogen) or syngas are important
