摘要： A process for producing olefins may include dehydrogenating a first alkane in a first reactor to produce a first effluent comprising at least one of a first n-olefin or a first diolefin; removing the first effluent from the first reactor; and regenerating the first reactor. The first reactor may include a first dehydrogenation catalyst and a first phase change material.

摘要： A process is disclosed for making CF3CF═CHF. The process involves reacting CF3CClFCCl2F with H2 in a reaction zone in the presence of a catalyst to produce a product mixture comprising CF3CF═CHF. The catalyst has a catalytically effective amount of palladium supported on a support selected from the group consisting of alumina, fluorided alumina, aluminum fluoride and mixtures thereof and the mole ratio of H2 to CF3CClFCCl2F fed to the reaction zone is between about 1:1 and about 5:1.Also disclosed are azeotropic compositions of CF3CClFCCl2F and HF and azeotropic composition of CF3CHFCH2F and HF.

摘要： The present disclosure relates to a crosslinking composition for use in crosslinking an aqueous suspension of guar, for use as a well treatment fluid and/or proppant carrier fluid for natural gas extraction. The present crosslinking composition is an aqueous suspension of hydroboracite. The composition may also comprise varying amounts of borax, canola oil, xanthan, glycerol, and/or NaOH. The composition may be selected to effect a desired delay in the crosslinking reaction in order to customize the viscosity and reaction time to the method of use, thereby maximizing proppant delivery while minimizing pump pressure.
