Inhibition of hydrogen production reactions in the wet dust removal system using CeCl3 solutions

Study of hydrogen explosion control measures by using l-phenylalanine for aluminum wet dust removal systems

“…According to the work by Wang Y. et al, [14][15][16][17] the initial temperature and pressure for each experiment were set to 50 C and 100 kPa, respectively. In addition, the reaction between aluminum particles and water can produce only hydrogen; thus, the change in the mole of the generated hydrogen can be characterized by the change of the pressure within the reactor.…”

“…At this time, no L-phenylalanine protective lm existed on the aluminum particle surface. According to the work by Wang Y. et al [14][15][16] and Xu K. et al, 17 aer all the Al 2 O 3 available on the surface has reacted with water and formed Al(OH) 3 , the aluminum core can react with Al(OH) 3 and generate hydrogen. Fig.…”

“…The inhibitors proposed by Wang Y. [14][15][16] and Xu K. 17 to inhibit the reaction between aluminum particles and water are precipitating inhibitors. Most of the adsorbent inhibitors are organic materials, which have polar genes and can be adsorbed by metal surface charges.…”

“…Wang Y. proposed the use of K 2 Cr 2 O 7 , Na 2 Cr 2 O 7 $2H 2 O, Cr(NO 3 ) 3 $9H 2 O, and CrK(SO 4 ) 2 -$12H 2 O, and Xu K. proposed the use of CeCl 3 to inhibit the reactions between aluminum and water in wet dust removal systems. [14][15][16][17] These inhibitors can effectively constrain the reaction between aluminum dust and water and intrinsically prevent the hydrogen explosions in wet dust removal systems. However, chromate is toxic, and the long-term exposure to chromate can cause cancer.…”

Research Progress of HP Characteristics, Hazards, Control Technologies, and Measures in China after 2013

“…At the meso level, for all large, medium, and small enterprises, they must select the appropriate and effective air purification equipment. At present, the purification methods for PM in tail gas primarily refer to mechanical precipitators [173][174][175][176], wet scrubbers [177][178][179][180], bag filters [181,182], electrostatic precipitators [183,184], some mixed type scrubbers [185][186][187][188], etc., from these it can realize all-round clean production. At the micro level, the movement behavior of PM in different types of air purification equipment needs to be deeply understood, which can provide a theoretical basis for more cost-effective air purification equipment technology research and development.…”
