Abstract
Fluidized bed reactors having centrally positioned heating means, as well as methods for their use, are provided. The subject reactors comprise a centrally positioned heating means (e.g. a susceptor rod) that, during operation, is at least partially immersed in a fluidized bed of particles. The subject reactors are further characterized in that, during use, a temperature gradient is produced within the reactor. The subject reactors find use in a variety of applications.
Claims25
A fluidized bed reactor comprising:
- a reactor vessel;
- at least one non-contaminating heating means centrally positioned inside said vessel such that during operation said heating means is at least partially immersed in a fluidized particle bed in said vessel wherein said heating means is a susceptor rod;
- and
- a means for generating an electromagnetic field inside said reactor vessel.
A fluidized bed reactor comprising:
- a reactor vessel;
- a susceptor rod centrally positioned inside said vessel such that said susceptor rod is at least partially immersed in a fluidized particle bed during operation of said reactor;
- and at least one radio frequency coil positioned in association with said vessel and capable of generating an electromagnetic field inside said vessel.
A fluidized bed reactor comprising:
- a reactor vessel fabricated from an inert, non-conductive material;
- a susceptor rod of a conductive material encapsulated in an inert material and centrally positioned in said vessel such that during operation said susceptor rod is a least partially immersed in a fluidized particle bed in said vessel;
- and
- a plurality of radio frequency coils externally positioned with respect to said vessel and capable of generating an electromagnetic field inside said vessel.
A fluidized bed reactor comprising:
- a reactor vessel fabricated from an inert, transparent material;
- a fluidized particle bed inside said reactor vessel;
- a susceptor rod centrally positioned inside said reactor vessel and at least partially immersed in said fluidized particle bed;
- and
- a plurality of radio frequency coils positioned in association with said vessel and capable of generating an electromagnetic field inside said vessel.
A fluidized bed reactor comprising:
- a reactor vessel;
- at least one non-contaminating heating means centrally positioned inside said vessel such that during operation said centrally positioned heating means is at least partially immersed in a fluidized particle bed in said reactor vessel, said centrally positioned heating means configured to produce a temperature gradient within said reactor vessel with a zone of highest temperature being proximal to said centrally positioned heating means.
