Mixed feeding

In the case of a simple eutectic system shown in Fig. 22-2, a pure solid phase is obtaiuea by cooling it the composition oFthe feed mix-...

There are many parameters influencing the size-related performance of a reactor where feed mixing is important concentrations of reactants, feed flow rate, feed pipe velocity, geometry and size of both reactor and stirrer, and stirrer rotational speed. The following remarks should be kept in mind when composing an experimental program for engineering studies ... 

A loss of the deionized water supply occurred during a workup test. Increased water usage for feed mixing, coupled with reduced membrane capacity while operating with colder water during the winter months, caused the deionized water supply to drop. 

Conventional Ni-based catalysts still dominate in SR applications however, ceria-supported noble metal catalysts have also attracted interest reeently. The study of Rh for both POX and ATR has increased sinee Rh is in general more active for reforming and is less prone to form carbon. H2 and CO selectivities in Rh-based catalysts have been shown to be affected by catalyst geometry. This indicates that feed mixing and mass transfer can play an important role. 

Weighed amounts of ingredients should be used where possible. This helps to ensure that the ingredients are added to the mix in the correct proportions. Some types of on-farm feed-mixing equipment are based on volume rather than weight. In these cases it is essential that the equipment... 

This change in catalyst hopper operation virtually eliminated the formation of coke deposits in the feed mixing zone. Catalyst-to-oil ratios as low as 2.5 have been achieved even with very heavy feedstocks. 

The specifications of a larger industrial screen granulator are given in Table 5.11. This machine is designed to sift and granulate mixed bodies of limited moisture content (e.g. 10% moisture) in the ceramics and chemical industry. Its cross section is shown in Fig. 5.18 feed mix falls into a hopper...
