Zeolites are usually considered to be acid catalysts, which prone deactivation due the coke deposition in hydrocarbon conversions such as methanol-to-olefins (MTO) reaction. Herein, a high-pressure MTO process with cofeeding H2 and H2O is reported, can effectively prolong catalytic lifetime of SAPO-34. The corresponding methanol handling capacity about 200 times larger than that under normal-pressure condition. Investigation reveals ultralong originates from hydrogenation ability sites on...
Cherry-red tobacco has aroused significant interest in both the academic and industrial fields due to its unique aroma style. In order analyze characteristics of intrinsic substance basis, compounds were analyzed by gas chromatography-mass spectrometry (GC-MS), verified sensory evaluation, a correlation analysis was further conducted. The evaluation suggested that significantly richer aroma, containing total 11 aromas, among which nutty, bean, herbal, spicy characteristic aromas. indicated...
Conversion of methanol to olefins (MTO) is an important non-oil alternative route for ethylene and propylene production, which has been industrialized based on a fluidized-bed process with small-pore SAPO-34 (CHA topology) molecular sieve as the active catalyst component. However, it remains challenge effectively regulate selectivity toward single or due limited selection insufficient understanding control principle. Herein, we report synthesis SAPO-14 (AFN ultra-small cage structure narrow...
Large pore high-Si beta zeolites (Si/Al = 136 to 340) were synthesized by a HF-assisted method, and their catalytic performance for the conversion of methanol propene was explored.
Homologous and heterologous micron-meter SAPO molecular sieves are treated facilely with morpholine (MOR) within a Teflon-lined stainless steel autoclave used as seeds to synthesize nano-sized SAPO-34.
High-Si single-crystalline beta zeolites with intracrystal mesopores were synthesized for the first time and investigated as catalysts methanol to propene (MTP) reaction.
The catalytic oxidation of ethylene glycol with O 2 to glycolic acid was carried out using a Pt/Sn-Beta catalyst in aqueous phase under base-free conditions, temperature range 30–70 °C, achieving yield up 73%.
Abstract Tailoring the morphology of a specific crystalline material through distinct crystal growth mechanisms (classical and nonclassical) is challenging. Herein, we report two unique morphologies medium‐pore (10×8‐ring) zeolite, ZSM‐57, prepared by employing an identical organic structure‐directing agent (OSDA) different inorganic cations, namely Na + K , denoted as ZSM‐57‐Na (pentagonal nanoplates) ZSM‐57‐K nanoprisms), respectively. The tunable twin domain size boundaries in both...
Recently, the scheme of model-X knockoffs was proposed as a promising solution to address controlled feature selection under high-dimensional finite-sample settings. However, procedure depends heavily on coefficient-based importance and only concerns control false discovery rate (FDR). To further improve its adaptivity flexibility, in this paper, we propose an error-based knockoff inference method by integrating features, statistics, stepdown together. The does not require specifying...

Quality control is important for tobacco industry and leaf the source material cigarettes product. For a certain brand's products, without known standard samples as center, it difficult to detect outliers of unknown groups with classical PCA. Although PCA has been widely used in NIRS tobacco, accuracy can not satisfy industrial requirements correctly classify products identify outliers. Therefore robust sparse (RSPCA) here NIR process, which advantages over both (RPCA) (CPCA) that RSPCA...
Abstract N-(4-cyano-2-nitro-phenyl)[NCP]-L-serine has been synthesized from L-serine. Crystals of NCP-L-serine • DMSO complex having good optical quality were grown solution. The crystal structure and the nonlinear properties determined. Second harmonic generation (SHG) measurements according to powder method reveals that possesses SHG activity.
