Time-dependent processes course content

The course described below is based on four weeks full time, corresponding to 4x40=160 hours. The split between lectures and working classes depends on the teacher s choice, but we found that the ratio 40/120 is convenient. The content of a typical Process integration course is outlined in Table 14.1, with indication to chapters in the present book. Hereafter we mention some pedagogical issues. 

Fig. 24 presents some computed results for the three--phase FT process and various catalyst concentrations. Here also the space-time-yield goes via a maximum value in dependence on the inlet gas velocity. The optimum gas velocity, i.e., that at which the STY is highest, increases with the reaction rate, i.e., catalyst content in the slurry. Of course, under nonisothermic conditions when the temperature is allowed to increase slightly the optimum gas velocity rises slightly as well. It is interesting to note that for 20 % wt. Fe in slurry which corresponds to the conditions... 

The course of biotransformation and the final product properties depend both on the type and composition of the enzyme complex and on the cellulose structure such as the average polymerisation degree and its distribution, crystallinity, capillary system and swelling behaviour as well as the physical-chemical parameters of processes such as ratio enzyme activity to cellulose content, time and temperature reactions. The increased susceptibility of cellulose chains is a result of the modified stmcture and developed intrinsic surface of cellulose obtained by using suitable pre-treatment methods, particularly mechanical processing. ... 

The content of individual dipeptides, of course, varies in different muscles and depends on many factors, such as age of the animal and type of processing. Breast muscles of poultry, for example, contain about 5-10 times higher amounts of carnosine and five times higher amounts of anserine than leg muscles (white breast muscles are involved in intense anaerobic metabolism and therefore require a higher buffering capacity).
