The source rock quality, organic pore structure, occurrence state and sealing mechanisms of shale gas in the Ordovician Wufeng – SilurianLongmaxi Formation (O3w-S1l), Fuling region, Sichuan Basin were studied using a series techniques including ultra-microscopic maceral identification, FIB-SEM, high temperature/pressure isothermal adsorption isotopic age dating noble gas. results show that: (1) O3w-S1l organic-rich was mainly formed sedimentary environment with productivity surface water...
As the hydrocarbon generation and storage mechanisms of high quality shales Upper Ordovician Wufeng Formation- Lower Silurian Longmaxi Formation remain unclear, based on geological conditions experimental modelling shale gas formation, accumulation as well their coupling relationships deep-water shelf in Wufeng–Longmaxi Sichuan Basin were analyzed from petrology, mineralogy, geochemistry. The are characterized by thermal evolution, intensity, good material base, roof floor conditions; not...
In view of strong heterogeneity and complex formation evolution organic pores, field emission scanning electron microscopy (FESEM), Raman spectrum fluid injection + CT/SEM imaging technology were used to study the macerals, pores connectivity in lower Paleozoic organic-rich shale samples from Southern China. Combined with mechanism hydrocarbon generation expulsion pore forming matter-based activated carbon, relationships between development matter type, process, diagenesis pressure explored...
In the second member of Upper Triassic Xujiahe Formation (T3x2) in Xinchang area, western Sichuan Basin, only a low percent reserves has been recovered, and geological model gas reservoir sweet spot remains unclear. Based on large number core, field outcrop, test logging-seismic data, T3x2 area is examined. The concept fault-fold-fracture body (FFFB) proposed, its types are recognized. main factors controlling fracture development identified, models FFFB established. refers to faults, folds...

Abstract Biologically significant clavilactones A, B, and the previously proposed D have been synthesized through iron‐catalyzed carbonylation–peroxidation of a 1,5‐diene. Three steps from aldehydes, alkenes, tert ‐butylhydroperoxide build up α,β‐epoxy‐γ‐butyrolactone skeleton as key building block for synthesis clavilactone family its derivatives. Based on our results, structure is not correct requires revision.
An intermolecular oxidative cyclization between thiophenols and alkynes for benzothiophene formation has been established. A variety of multifunctional benzothiophenes are synthesized. In addition, we demonstrated that the obtained can be used further transformation to give diverse derivatives efficiently selectively.
Iron-catalyzed acylation-oxygenation of terminal alkenes is reported. Acyl radicals generated by the oxidation aldehydes add to and followed intramolecular oxygenation give functionalized 2,3-dihydrofuran derivatives bearing a quaternary carbon.
Extensive efforts have been devoted to developing desulfurization catalysts effectively remove sulfur from fuel. Active phase metals including cobalt, nickel, molybdenum, and tungsten extensively used in industry for hydrotreating/hydrodesulfurization over 50 years. However, while it is desirable use inexpensive materials do the same job, a grand challenge. Herein, we report Fe-based sulfide catalyst that tuned by zinc with high activity HDS, which shows an industrial application potential...
Abstract Zeolite Y, with a high SiO 2 /Al O 3 ratio (SAR), plays an important role in fluidized catalytic cracking processes. However, situ synthesis of zeolite Y SARs remains challenge because kinetic limitations. Here, SAR 6.35 is synthesized by hydroxyl radical assisted route. Density‐functional theory (DFT) calculations suggest that radicals preferentially enhanced the formation Si‐O‐Si bonds, thus leading to increased SAR. To further increase SAR, dealumination process was carried out...
Multi-substituted pentacenes, such as 1,2,3,4,6,8,9,10,11,13-decasubstituted pentacenes (Type I), 1,2,3,4,6,13-hexasubstituted II), 1,2,3,4-tetrasubstituted III), and 2,3-disubstituted IV), 1,2,3,4,6,11-hexasubstituted naphthacenes V), VI), VII), were prepared by a homologation method. The method involved the conversion of phthalic acid ester derivatives to two ring extended via diynes metallacyclopentadienes using transition metals, Zr Rh. For formation Type III IV VII,...
With the aim to optimize alkaline treatment of zeolites obtain hierarchical zeolites, dissolution and absorption mechanisms relevant mesopore formation were investigated at an atomistic scale by density functional calculations. In processes, dealumination is energetically more favorable than desilication, though both processes can occur. The dissolved Al species prefer be absorbed back onto zeolite surfaces whereas Si tend aggregate in solution. process promotes but hampers formation, laying...
