ฉันรักแปลFig. 1 shows a schematic diagram of the continuous feeding fluidized
bed reactor system for catalytic pyrolysis of black-liquor lignin
by co-feeding with different plastics. The system has been
shown in elsewhere (Zhang et al., 2014). The reactor was designed
for handling 5–200 g/h feedstocks with 32 mm ID and 280 mm free
board height. 30 g of catalyst was used in all experiments.
Feedstocks are fed into the reactor by two continuous feeding
screw feeders. The two screw feeders were designed for quantitative
determination and feeding into reactor rapidly, respectively.
The fluidizing gas (N2, 99.99%) is introduced into the reactor at a
rate of 250 mL/min. The hopper is swept with N2 at a rate of
100 mL/min to maintain an inert environment of the feeding unit.
A cyclone is set outside of the reactor to remove and collect small
particles which contain catalyst and char. The vapors are introduced
into a two-stage condenser apparatus followed the cyclone.
The first condenser unit is located in an ice water bath at temperature
of about 0 C. The secondary condenser unit is located in a
dry ice/ethanol bath at 55 C. Finally, the non-condensable gases
are collected by gas sampling bags and analyzed by GC/FID and
GC/TCD. The condensable liquid products are then analyzed by
GC/MS. For a typical run, the experiment is conducted about
20 min. After reaction, the carrier gas is switched to O2 at
250 mL/min to calcine the catalyst and burn the produced char
and coke. Then the effluent gas is sent into a copper converter
which is maintained at 250 C to convert CO to CO2. After the
absorption of water with silica gel, the CO2 was captured by an
ascarite trap. Therefore, char and coke carbon yield can be obtained
via the mass of CO2 captured by the ascarite trap.

Ek is lief vir die vertaling van Fig. 1 toon 'n skematiese diagram van die deurlopende voeding fluidized
