Details of the main components are shown in Table 4, referring to the design data of the reference plant and similar cases in previous studies.…”

Production of Hydrogen‐Rich Syngas from Lignite using Different Pyrolysis Methods

“…More than 90 % of lignite exploited worldwide is still combusted directly for power generation in electric power stations near coal mines. In this way, resources cannot be utilized efficiently and cost effectively, and high emissions of carbon dioxide occur …”

“…More than 90 %o fl ignite exploited worldwide is still combusted directly for power generation in electric power stations near coal mines.I nt his way,r esourcesc annot be utilizede fficiently andc ost effectively,a nd high emissions of carbon dioxide occur. [9][10][11][12] If ah igh yield of hydrogen-rich syngas can be achieved through the production and transformation of hydrogen by efficient and low-carbonp yrolysis of lignite with ah igh hydrogenc ontent, it will significantlyf acilitate the transformation of the worlds energy supply from fossil energy to new energy.V arious influencing factors during lignite pyrolysis, such as the pyrolysis temperature, [13] heating rate, [14,15] size of the coal particles, [16] and additiono facatalyst, [17][18][19][20] have been studied extensively.However, the selection of an appropriate pyrolysis method should be the most fundamental and efficient way to improve the efficiency of hydrogen production through the pyrolysis of lignite.I nr ecent years,m icrowave pyrolysis,a sanew type of technology for cleaning and utilizing coal, has been applied in the pyrolysis of lignite and presentssignificant advantages such as auniqueheat-transfer profile,r eadily controlled pyrolysis,a nd high yields of the target products. [21] Therefore,l ignite from Dongsheng in Inner Mongolia, one of the regions with the largestr eserves of lignite in China, was selected as the subject of our research.…”

Permittivity‐Based Microwave Absorption Characteristics of Dongsheng Lignite during Pyrolysis

“…The pyrolysis of the lignite can be used as an important basic step in the comprehensive utilization of the coal, and the effects of temperature, heating rate, granularity and catalyst as well as changes in pyrolysis products during the pyrolysis have been researched by many scholars widely and thoroughly. As a new clean coal technology, microwave pyrolysis has an easy‐to‐control process and high yield of the objective product due to its fast heating rate.…”
