使用微波发生器 (GM)(等离子)和磁控管加热反应器(图 2a),温度保持在38℃,当温度低于38℃时,微波发生器自动启动。

研究中使用的超声波发生器 (GU) 安装在 HFAR 的每个区域(图 2b)。各区域配备了四个超声波换能器,频率为 20 kHz,功率为 95 W。每个 GU 都集成了一个控制面板来控制其工作。

在中试多区水平流反应器HFAR上部,各工段均设有底物补充、污泥、沼气收集以及温度和pH测量的端口,这为HFAR各工段废水投加、厌氧污泥再循环和沼气分析提供了可能。

水力停留时间(HRT)24小时。每个系列的持续 30 天,允许反应器内容物交换 30 倍。

 The reactor was heated using microwave generators (GM), (Plasmotomies) with magnetrons (Figure 2a).The temperature was maintained at 38 , and when it dropped below, the microwave generators automatically started.

The ultrasonic generators (GU) used in the study were installed at each section of the HFAR (Figure 2b). Sections were equipped with a package of the four ultrasonic transducers with a frequency of 20 kHz and a power of 95 W. Each GU was integrated with a control panel to control its work.

In the upper part of HFAR, in all sections, there were ports for substrate supplementation, sludge, and biogas collection, as well as the temperature and pH measurement, which created the possibility of wastewater dosing to the various sections of HFAR, anaerobic sludge recirculation, and biogas analyzing.

The sludge from the bottom of the thickener was recycled and then mixed with the raw wastewater. Effluent was discharged outside the technological system.

Figure 4. Schematic diagram of the lab-scale flow and catalyst recycling experimental system and table of initial stream and reactor concentrations.

这个装置设计有三个独立的区域,使得碱和催化剂在混合之前能够与其他化学试剂分开。每个流程中的原料(如图4)都被保存在配有磁力搅拌器的玻璃容器中。一个由聚四氟乙烯制成的盘管反应器(容量为10.9毫升,内径为1.5毫米)被放置在设定为70°C的超声波浴中。当反应完成后,产物流通过醋酸水溶液(pH值约为5.5)进行冷却。随后,进行相分离,有机相被引导回A流进料容器。在这里,它与新的催化剂混合,然后再次进行反应。这个循环过程导致A流进料的有机相被稀释(见图4的示意图)。

For this set up, three separate streams were employed, keeping the base and catalyst separate from the other reagents prior to the mixer. The feeds for the three streams (see Figure 4) were kept in magnetically stirred glass vessels, and the PTFE coil reactor (10.9 mL volume and 1.5 mm internal diameter) was placed into an ultrasonic bath at 70 °C to avoid tube clogging by surface crystallization of the potassium bromide byproduct. Post reaction, the product stream was quenched with an aqueous acetic acid stream at around pH 5.5 and was observed to give the predicted separation of the starting material and catalyst in the organic phase from the acetic acid salt of the product in the aqueous phase. After phase separation the organic phase was returned to the Stream A feed vessel and mixed with the fresh catalyst. This recycle of the separated organic phase post reaction consequently dilutes the Stream A feed .

Reactor design A single CSTR unit consists of three main components, including a polytetrafluoroethylene (PTFE) reactor block, a heat-resistant glass cover and a stainless steel cover (Fig. 1a).

The PTFE reactor is a 30 mm × 30 mm square block with a thickness of 19 mm. The cylinder-shaped inner chamber has a diameter of 18 mm and a depth of 10 mm. An O-ring gap surrounds the chamber for the 1/16′′ FEP O-ring with a silicone core. The glass cover is heat-resistant borosilicate glass with dimensions of 30 mm × 30 mm × 4.8 mm. The stainless steel cover is super-corrosion-resistant 316 stainless steel with dimensions of 30 mm × 30 mm × 3.2 mm. All extruded 2D shapes were fabricated using water jet machining. In addition to 2D shapes, the reactor chamber and the O-ring gap were machined using CNC milling. Multiple CSTR units are mounted on an aluminum holder (Fig. 1b). The aluminum holder (150 mm × 70 mm × 3.2 mm) can hold up to 8 CSTRs. All connection ports have 1/4-28 threads, which can be directly connected using common fittings.

We designed the platform where all starting materials can be fed into the photo-CSTR via the slurry pump (Figure 2a). With the intention to use gravity to enhance solid transport and minimize clogging, the slurry pump is positioned ~300 mm above the CSTR. The system is pressurized via a pressurized fraction collector, where 10 psig argon is applied directly to the collection chamber to prevent gas evolution in the reactor (Figure 2b).

Water was circulated through the jackets of the COBR at preset temperatures by three water baths (GP 200) in order to establish three temperature zones (shown as different colors and line widths in Figure 2) for reaction and crystallization. Six thermocouples (T1−T6 in Figure 2) were employed to record the temperature profiles of the operation. The temperature of seed suspension was controlled and maintained by a separate water bath to achieve the required supersaturation. The tubing connecting the seed suspension with the COBR was properly insulated to ensure the correct seeding temperature.
