The fluidized bed know-how developed has also led to the development of a revolutionary technology for the production of styrene from ethylbenzene using a riser reactor and a gallium based catalyst.
CPP uses a riser reactor, a quenching technology, and a cross current degassing device to minimize the flue gas adsorbed and entrained by the regenerated catalyst (see Table 2).
Comparison with literature data for risers using A-type powders is also fair.
In this work, optimization of the FCC riser has been carried out using a detailed riser process model of a six-lumped kinetic model to maximize the conversion of gas oil to propylene, which is a major building block for the polypropylene production.
The experiments were conducted using a transparent riser pipe of 3.1 m length and 33 mm inner diameter.
Production rates in the range from 5to2020 mg/h were achieved by using an optimized riser reactor design, which enables reduction of undesired wall-sticking of the catalyst particles and SWCNTs.
The technician said that rather than trying again with the saw, the plan now was to use a large shear to cut the riser.
The catalyst particles recirculated between two sections by using a draft tube riser.
Hu [49] studied the effect of hydrocarbon partial pressures on propylene yield by using a Davison circulating riser (DCR) and their results are summarized in Table 7.
If you want to secure the riser piece further, you can use a nail gun to nail the very top of the plank in place, as the nails will be concealed by the thread edge.
