Activity and characterization of coprocessing catalysts produced from an iron pentacarbonyl precursor

Scavenging H2S(g) from oil phases by means of ultradispersed sorbents

“…Very high reaction rates were reported when ultradispersed catalysts were employed for co-processing [1], coal liquefaction [2] and hydrocracking [3,4]. Moreover, ultradispersed catalysis was successfully applied for upgrading of extra heavy oil.…”

Effect of microemulsion variables on copper oxide nanoparticle uptake by AOT microemulsions

“…Formation of well-dispersed colloidal nanoparticle catalysts is crucial for heterogeneous catalysis in organic media [1][2][3][4][5][6][7][8][9][10][11][12]. However, maintaining stable dispersion of the particles is a challenging issue, since these particles tend to agglomerate with time in order to reduce the high surface energy [13].…”

“…One approach of minimizing particle agglomeration is to prepare the catalyst in situ. For example, very high reaction rates were attained when in situ prepared ultradispersed catalysts were employed for hydrocracking [1,2], coprocessing [4], and coal liquefaction [12]. In these investigations organometallic precursors were dissolved in the organic media to ensure intimate dispersion, then the catalyst was prepared in situ by thermal dethey inherently suffer from low solubilization/stabilization capacities of the different species [15,16].…”

Upgrading of Sugar Cane Bagasse by Thermal Processes. 6. Simulated Distillation of Oils Obtained From Coal Co-Processing With Sugar Cane Bagasse Oil

“…This process consists in liquefacting coal into a heavy oil not derived from coal. This heavy oil can be heavy petroleum, anthracene oil or heavy bitumens (Moschopedis and Hepler, 1987;Yoshida et aI., 1988;Boehm et aI., 1989;Lugini and Lett, 1989;Miller et aI., 1989;Herrick et al, 1990;Rincon et al, 1986).…”
