Catalytic effect of black liquor on the gasification reactivity of petroleum coke

Preliminary study on co-gasification behavior of deoiled asphalt with coal and biomass

“…A moderate gasification condition can be realized by adding catalysts, and the most effective catalysts in carbon gasification are alkali metals (such as potassium) [17,18]. Compared to these expensive catalysts, using some other inexpensive alkaline-rich materials as substitutes is reasonable [11,17]. Biomass, especially the herbaceous plant, is usually rich in alkali compositions.…”

“…So the traditional feeding methods applied by coal or biomass are not suitable for DOA gasification [10]. ( petroleum char [7,11,12]. Therefore, a higher gasification temperature must be used for gasifying this kind of material, which will increase the energy consumption and the cost of gasification.…”

“…Recently, the co-utilization of coal and biomass has been studied and the possibility that use biomass as a catalyst in coal gasification has been reported [17,21,22]. However, few researches focused on the co-gasification of biomass and DOA [11,23].…”

“…In fact, in 1980s, Cugini et al [15] has studied the co-processing of coal/oil, although their purpose was to get more distillate products. And in recent years, the co-gasification of petroleum coke and coal slurries were studied [11,16], which is comparable to the co-gasification of coal and DOA.…”

Investigate the kinetics of coke solution loss reaction with an alkali metal as a catalyst based on the improved genetic algorithm

“…Therefore, coke plays an important role in many industries. During the last three decades, there are increasing interests in those factors that influence the gasification rate of coke (Hijiriyama et al 1983;Zamalloa and Utigard 1995;Eatough et al 2007;Grigore et al 2008;Pusz et al 2010;Zhou et al 2010). Further, the reaction between carbon in coke and carbon dioxide is also gasification, and so-called coke solution loss reaction (Wang et al 2016), which is the main reason leading to fragmentation and pulverization of coke in the middle and lower part of blast furnace (Wang et al 2017).…”
