Abstract

Fluid catalytic cracking (FCC) is an important process in petroleum processing. Effective monitoring of the status and quality of FCC is vital. Accurate description of the relationship between process and quality variables is the basis of quality-driven monitoring. Many process variables affect the quality of FCC; some of these effects are linear, and others are nonlinear. We propose a combination method from the perspective of linearity and nonlinearity to improve the monitoring performance of FCC quality. Partial least squares (PLS) is initially used to extract linear features, and its residual space is saved as the input of the deep feedforward neural network (DFNN). DFNN is then used to extract nonlinear features for the further decomposition of subspaces. The PLS-DFNN method accurately describes processes involving linearity and nonlinearity. We construct three monitoring statistics to characterize the types of faults. The proposed method proves its excellent effect on a numerical simulation data set. It effectively distinguishes the types of faults on the Tennessee Eastman process data set, and the fault detection rate is superior to other related methods. Finally, we apply this method to the actual FCC and verify the superiority of this combination. [ABSTRACT FROM AUTHOR]

Abstract

Pleated filter cartridges with high pleat ratios and large filter surface are found to have great instances of patchy cleaning. In order to improve the intensity and uniformity of filter cleaning, a novel colliding pulse-jet cleaning method was designed and tested in this study. An experimental pulse-jet cleaning dust collector (the filtration chamber is 1225 × 750 × 1000 mm (width × depth × height)) was built with two nozzles installed over the filter cartridge (ϕ320 × ϕ240 × 660 mm) and on the cartridge bottom. The nozzle outlet pressure, pulse jet performance (intensity and uniformity), and compressed air consumption were studied. The effect of the trigger time difference between the top and bottom pulse jets on the performance was researched. This study demonstrated that the non-time-differenced colliding pulse-jet mode increased the pulse-jet intensity obviously to 2.56 times compared with the top-jet-only mode with some more air consumption (about 1.85 times than that in top-jet-only mode), but the pulse-jet uniformity slightly worsened. The pulse-jet intensity could be enhanced remarkably to 5.49 times if the colliding pulse jet was controlled in the strategy of varying trigger time difference, with the uniformity also increased obviously.

Abstract

Very recently, transition metal phosphides (TMPs) have emerged as low-cost and robust co-catalysts for decorating graphitic carbon nitride (g-C3N4) for photocatalytic hydrogen (H2) evolution. However, to date, little work has been done regarding the decoration approaches to hybridize TMPs on the g-C3N4 surface with homogeneous dispersion and intimate interfacial contact. Herein, we present a facile and convenient route to in situ incorporate g-C3N4 nanosheets (NSs) and Ni2P nanocrystal (NC) co-catalysts via a one-step co-heating solution approach. The Ni2P/g-C3N4 (in situ) hybrid photocatalyst achieved a far superior H2 production rate (2849.5 μmol g−1 h−1) and durability (no decrease after 4 cycles of reaction within 20 h) compared to the Ni2P/g-C3N4 (self-assembly) sample. The apparent quantum yield (AQY) of 18.8% at 420 nm was also much higher than that of other TMP co-catalyst loaded g-C3N4 hybrid photocatalysts. A possible Ni(δ+)–N(δ−) chemical coupling in the Ni2P/g-C3N4 (in situ) hybrid composite was proposed and corroborated by X-ray photoelectron spectroscopy (XPS) and X-ray absorption spectroscopy. The unique Ni(δ+)–N(δ−) chemical bonding states between g-C3N4 and Ni2P significantly accelerate the photo-generated charge-carrier separation and extraction from g-C3N4, as well as maintaining the H2 production durability. We believe that the hybridization route presented in this work will be extended to construct other TMP integrated photocatalysts toward efficient and stable solar water splitting.
