Paper Number: WPC-22-41163
... and catalyst circulation rate. In a fluidized bed reactor, the fluidity of catalysts (which is dependent on hydrodynamic parameters such as the size of bubbles) affects the reactivity of the process. We have measured bubble diameter in a fluidized bed of FCA catalyst in order to determine its fluidity...

In these experiments it was shown that the improvement of yields over the inert ceramic materials are in a similar range as with the catalysts. Also it was shown that the yield of products are in similar...

.... The technique and technology available allows us to drill horizontal wells with a long and medium radius of curvature. The shortened motors of 95 and 105 mm diameter, which are now in the stage of development, will provide for drilling short radius wells (20–30 m). In the paper, the results of drilling...
