Embodiment 1

[0070] Example 1: Using corn stalks to produce hydrogen / methane mixed hydrogen with a mixing ratio (volume ratio) of 1:2

[0071] In this example, corn stalks produced in Songyuan City, Jilin Province were selected as the biomass raw material for the preparation of mixed hydrogen alkanes. The quantitative analysis of its components (weight %) is shown in Table 1 below.

[0074] Cut the above corn stalks into small sections with a length of 5 cm, perform physical pretreatment by steam explosion, and send the pretreated corn stalks into figure 1 in the system shown. Among them, the hydrogen production reactor 2 is a medium temperature continuous flow stirred reactor (CSTR), and the methane production reactor 3 is a medium temperature upflow anaerobic sludge bed (UASB) reactor. At the same time, the hydrogen production reactor and ...

Abstract

The invention discloses a monitoring system used for a multistage biomass fermentation reaction system and a monitoring method thereof. The system comprises a sensor and/or a probe, a central controller or a head server and an actuator, wherein the sensor and/or the probe is used for monitoring one or more process parameters and/or operation conditions of at least two biomass fermentation reactors in the multistage biomass fermentation reaction system; the central processor or the head server is used for realizing transmission of data or information by a digital optical cable or an analogue signal optical cable and the sensor and/or the probe, and determining at least one process parameter and/or operation condition for keeping or adjusting other biomass fermentation reactors according to monitored result of at least one process parameter and/or operation condition of the at least one biomass fermentation reactor; the actuator is used for keeping or adjusting the process parameter and/or the operation condition, and realizing transmission of data or information with the central controller or the head server by the digital optical cable or the analogue signal optical cable.

Description

technical field [0001] The invention relates to a monitoring system and a monitoring method for a multi-stage biomass fermentation reaction system, in particular, to a monitoring system and a monitoring method for producing mixed hydrogen with at least two biomass fermentation reactors. Background technique [0002] Fossil energy is still the main source of energy in my country so far, but the proven reserves and mining quantities of high-quality oil and gas are far from meeting future demand, while coal has relatively low calorific value and heavy pollution, so it is not appropriate to increase the proportion of energy. Relatively, biomass energy resources are abundant, and it is estimated that the world accumulates about 220 billion tons of biomass through photosynthesis every year, and biomass energy can be converted into modern high-quality energy through biological or chemical gasification or liquefaction, which not only improves Thermal efficiency reduces environmental...
