| 摘要 |
The reactor system (40) comprises a first reactor unit (47) with an outlet (50) for an product stream comprising a solid phase product in particulate form, and a fluidized bed reactor unit (41) provided with a particle inlet (64) coupled to the outlet of the first reactor unit (47) through a transportation pipe (60), which comprises mechanical displacement means (62) embodied as a screw and driven to rotate at a predefined rotation speed, and a densification zone (65) defined between said mechanical displacement means (62) and said particle inlet (64), in which densification zone (65), in operation, a density of the product stream is increased, said densification zone (65) defining a flow direction into said fluidized bed reactor unit (41). An unobstructed space (A) is defined in said fluidized bed reactor unit (41), the space extending from said particle inlet (64) over a distance of at least 0.4·D in said flow direction where D is the internal diameter of said fluidized bed reactor unit (41) at the level of said particle inlet (64).
