However, the acidity of a catalyst particle is not always related to its density9. By using microfluidics for high-throughput analyses of catalyst particles, the level of detail for bulk characterization and the statistical relevance of single particle characterization can be improved. To realize a ...
There is no reason in the world that cans of Coke should contain 355 milliliters, except that size closely approximates the old 12-ounce can.Products are now labeled with metric quantities, but just try asking for half a kilo of ground beef at the supermarket. Even though the butcher has...
It provides a better interpretation on the status of coke deposition in the downstream equipment while prompt actions to correct the situation can be made before serious damages occur. Consequently, the unscheduled maintenance is reduced while the process on-stream time is lengthened. In addition, ...
Ellwoodb and Emma Scobbieb a School of Chemistry, University of Bristol, Cantock's Close, Bristol, UK BS8 ITS h Health and Safety Laboratory, Health and Safety Executive, Broad Lane, Sheffield, UK S3 7HQ Samples of air taken from a high temperature coke oven plant were assayed for ...
The degree of graphitisation was found to be dependent on temperature. On the other hand, the graphitisation at each temperature was instantaneous, even at as low a temperature as 973 K and no dependency on time could be noticed. The thermal diffusivities of the coke samples taken from ...
The isotropic chemical shifts of the aluminum species observed through 2D MQMAS technique when compared with the 1D MAS spectra showed unambiguously that the peak in the [delta]2[approximate]32ppm region can be attributed to a species with tetrahedral coordination. This species was readily removable...
Results of FSI model indicated that RF can provide a satisfactory prediction of FSI with the correlation of determinationR2=0.96 and mean square error of 0.16 from laboratory FSIs (which is smaller than the interval unit of FSI; 0.5). Based on this result, RF can be used to rank and ...
There are several methods to determine the density and surface tension of slags. A commonly used technique is the sessile drop technique since it allows determination of both the density and surface tension, and can be performed at high temperatures in controlled gas atmospheres. This technique ...
Nevertheless, it took until 1870 for Pierre Berthelot to be credited with the fabrication of the first bomb calorimeter, a figure who was also credited with inventing the concept of exothermic and endothermic reactions. These facts represent the origins of the first modern calorimeters and can be...
