专利号:WO-2025004059-A1 优先权日:2023-06-30 标题:Synthesis of polyether polyols based low dosage gas hydrate inhibitors using double metal cyanide catalyst 发明人:KUMAR UMESH; KUMAR ASHEESH; VERMA AKASH; DUBEY SADHBHAWANA; KUMAR SANAT; GANGULY SUDIP KUMAR 权利人:COUNCIL SCIENT IND RES 摘要:A series of different metals (Zn/Fe/Co/Sn/Mg/La/Al/Cr) based double metal cyanide (DMC) catalyst is disclosed herein. Benzene-1,3,5-tricarboxylic acid (BTC) is incorporated as an organic complexing agent (CA) in the DMC catalyst. The DMC catalysts prepared with BTC and its derivatives as CAs are highly active towards ring opening polymerization (ROP) of propylene oxide (PO) and imparts heterogeneity as compared to the DMC prepared without any CA. The polyether polyols (PEPOs) with controlled molecular weight (Mw), polydispersity index (PDI), hydroxyl value (OH), and iodine value (I2) are produced using a DMC catalyst. PEPOs of the present invention relate to low-dosage gas hydrate inhibitors (LDHIs) utilized to mitigate/manage the formation, growth, and deposition/agglomeration of gas hydrate crystals in oil and gas production pipelines (especially applicable to deep and ultra-deep developments), and drilling or fracturing operations during natural gas hydrate exploration.
专利号:US-2024335827-A1 优先权日:2021-06-25 标题 :Iron-based complexes for use in the catalysis of hydrosilylation reactions 发明人:Song datong; LIANG QIUMING; JIMENEZ SANTIAGO JOSÉ LUIS 权利人:GOVERNING COUNCIL UNIV TORONTO 摘要:There is provided an iron-based complex of formula (IA) or (IB) or a solvate thereof (IA) (IB). The iron-based complex can be used for catalyzing a hydrosillation reaction, such as the hydrosilylation of a ketone or an aldehyde. Also provided is a method for preparing a silyl ether from a ketone or an aldehyde comprising the hydrosilylation of the ketone or aldehyde in the presence of the iron-based complex. Another method is provided for the synthesis of an alcohol from a ketone or an aldehyde comprising the hydrosilylation of the ketone or aldehyde in the presence of the iron-based complex to form a silyl ether, and then hydrolyzing the silyl ether to obtain the alcohol. A process for preparing the iron-based complex is further disclosed.

专利号:US-2025270101-A1 优先权日:2023-06-07 标 题:Catalyst-Sorbent Structure for Ammonia Synthesis And Sorption and Method of Ammonia Production 发明人:GILBERT TRISTAN; BAERT KAREN; TONKOVICH LEE 权利人:AMMOBIA INC 摘要:An active catalyst for ammonia synthesis is integrated with a specialty sorbent in a composition or composite, such that the catalyst portion and the sorbent portion are in direct intimate contact, which overcomes the thermodynamic limits for conversion. The sorbent may comprise a metal halide absorbent, zeolite adsorbent, other material absorbents or adsorbents, to capture ammonia as it is produced in intimate or near molecular contact with the catalyst, wherein the composition/composite may be provided in the form of a granular or pellet structure. By removing ammonia essentially as it forms, the forward reaction for producing ammonia can continue nearly unabated such that high net conversion can be achieved in a single pass or cumulative within segmented reactors as operated in series.

Various Schiff bases are incorporated as organic complexing agents in the DMC catalysts. The catalysts of the present invention are highly active for the ring opening polymerization (ROP) of epoxides in the presence of different H-functional initiators to produce polyether polyols (PEPO) with a wide range of average molecular weight (Mw) and polydispersity index (PDI).
