Pellet oxygen sensors

Ti02 Prototype sensors oxygen sintered pellet [11]... 

Wet explosion pretreatment [7] was perfonned batch-wise by suspending 350 g wheat straw pellets in 1.81 of deionized water in a 3.5-1 high-pressure reactor with a paddle stirrer with a maximum stirring speed of 2,000 rpm. The reactor was equipped with an injection device for injection of H2O2 solution, pure oxygen, or air. The reactor was heated by water jacket, which was coimected to a heat exchanger controlled by an oil heater. The highest temperature in the reactor was 190 C. The temperature and pressure inside the reactor were monitored by two temperature sensors (one in the bottom and one in the head space) and one pressure sensor. After the pretreatment, the material was flashed into a 5-1 container connected to the reactor.
