Abstract: Metal-organic framework materials (MOFs) are highly porous entities comprising a multidentate organic ligand coordinated to multiple metal centers. MOFs having ambient condition stability may comprise a plurality of metal clusters comprising one or more M4O clusters (M is a metal), and a plurality of 4-pyrazolecarboxylate ligands coordinated to the plurality of metal clusters to define an at least partially crystalline network structure having a plurality of internal pores. The MOFs may have a Pa3 symmetry, which upon activation may convert into Fm3m symmetry. Methods for synthesizing the MOFs may comprise combining a metal source, such as a preformed metal cluster, with 4-pyrazolecarboxylic acid, and reacting the preformed metal cluster with the 4-pyrazolecarboxylic acid to form a MOF having an at least partially crystalline network structure with a plurality of internal pores defined therein and comprising a plurality of metal clusters coordinated to a multidentate organic ligand comprising 4-pyrazolecarboxylate.

Abstract: A method for operating an integrated system for producing olefins may include contacting a hydrogenation feed with a first hydrogenation catalyst to produce a hydrogenated effluent, the hydrogenation feed including at least a portion of a first process effluent from a first olefin production process and at least a portion of a second process effluent from a second olefin production process. The hydrogenation feed may include at least hydrogen, ethylene, carbon monoxide, acetylene, methyl acetylene, and propadiene, and the first hydrogenation catalyst may be a hydrogenation catalyst having a temperature operating range of at least 40° C. The hydrogenated effluent may include methyl acetylene, propadiene, or both. The method may further include contacting at least a portion of the hydrogenated effluent with a second hydrogenation catalyst, which may cause hydrogenation of at least a portion of the methyl acetylene and propadiene to produce an MAPD hydrogenated effluent.

Abstract: The disclosure provides use of an efficient, recyclable, green and friendly catalyst to realize a method of hydrogenation of an unsaturated alkene, and a method for preparing biodiesel through the transesterification of soybean oil with ethanol. The method of hydrogenation of the unsaturated alkene comprises performing a hydrogenation reaction of an unsaturated alkene at ambient temperature and atmospheric pressure by using a CO2 and magnetic dual-responsive mesoporous poly(ionic liquid) as a catalyst I, and using n-hexane and water as a solvent, to obtain a corresponding saturated alkane. The method for preparing biodiesel through transesterification of soybean oil with ethanol comprises performing a transesterification reaction of soybean oil with ethanol at a temperature of 25-90° C. and atmospheric pressure by using a CO2 and magnetic dual-responsive mesoporous poly(ionic liquid) as a catalyst II, to obtain the biodiesel.
