It mimics the behavior of a countercurrent moving bed, in which a stream of solids flows countercurrent to an inert fluid and past a stationary reactant inlet, by periodically changing feed locations sequentially along a fixed bed.
A hybrid sensor system for accurate detection of the metal grade of a stream of falling solid waste particles is investigated and experimentally verified.
A dirty MRF takes in a broad stream of solid waste and separates out recyclable materials through manual and mechanical sorting.
Time contributor James Poniewozik wrote that "Black Light Attack!" presented the balance 30 Rock "has reached with Liz Lemon's character, allowing her to be simultaneously nerdy/awkward ... and strong ... Throw in a steady stream of solid throwaway jokes ... and you had a worthy toofer".
He also turned out a steady stream of solid dramas as well as 13 episodes of the drama Sailor of Fortune and 15 episodes for ITV of the sitcom The Adventures of Aggie.
In the model, a cross-flow dryer is treated as a series of gas-solid contact stages, each purged by a stream of drying gas while wet solids are passing through.
At process conditions of 380 °C and 180 s isothermal hold time, a stream containing less than 20% phenolics (carbon basis) was produced, and upon subsequent fast pyrolysis of the residual solid a stream of 81.5% levoglucosan (carbon basis) was produced.
The eluate was evaporated on a heating block at 40°C under a stream of nitrogen to obtain a solid residue.
The organic phase was evaporated to dryness under a stream of nitrogen and purified by solid-phase extraction.
Piperidine (0.1 mL) was added dropwise to a mixture of salicylaldehyde (2.0 mL, 18 mmol) and ethyl acetoacetate (3.0 mL, 24 mmol) in EtOH (1.0 mL) The reaction mixture was stirred under microwave irradiation for 5 min (hold time) at 50°C (initial power 20 W) and then was cooled in a stream of compressed air, resulting in a yellow solid.
