Abstract:
A fluidized bed coking reactor apparatus comprises a reaction vessel; a temperature sensor inside the reaction vessel for measuring a reactor temperature, a solids feed mechanism for feeding solid particles into the reactor vessel at a mass flow rate, a feed material feed mechanism for feeding feed material into the reactor at an operating feed rate; and a supervisory controller programmed to determine an upper feed material feed rate of the reactor when operating at the reactor temperature and receiving solid particles at the mass flow rate. The upper feed material feed rate is defined as a feed rate of feed material deposited onto a selected fraction of a fluidized bed of solid particles that causes defluidization in the reactor when the reactor is operating under conditions having a selected degree of backmixing in the fluidized bed, wherein the degree of backmixing is modeled as a selected number of reactors arranged in series and each operating under continuous well-mixed conditions, with the selected number of reactors being an integer between one and infinity.
Abstract:
A process is disclosed for the catalytic conversion of biomass material whereby particulate biomass material is contacted with a particulate heat carrier material in a fluidized bed.
