The present disclosure provides mesoporous catalyst compounds and compositions having one or more group 13 atoms. The present disclosure further relates to processes for converting hydrocarbon feedstocks to small olefins. In one aspect, a catalyst compound includes a zeolite having a structural type selected from MFI, MSE, MTW, Theta-One (TON), Ferrierite (FER), AFI, AFS, ATO, BEA, BEC, BOG, BPH, CAN, CON, EMT, EON, EZT, FAU, GME, GON, IFR, ISV, ITN, IWR, IWW, LTL, MAZ, MEI, MOR, MOZ, OFF, OKO, OSI, SAF, SAO, SEW, SFE, SFO, SSF, SSY, and USI, or a combination thereof, the zeolite having a silicon to aluminum molar ratio (Si/Al ratio) of from about 5 to about 40. In one aspect, a catalyst composition includes the catalyst compound and one or more group 13 metal.

Mesoporous catalyst compounds and uses thereof

Provided herein are methods of novel methods of synthesizing a metal-organic framework system by vapor-phase appending of a plurality of ligands appended to a metal-organic framework. Also, provided are methods of recycling metal-organic framework systems by detaching the ligand and re-appending the same ligand or appending a different ligand to the metal-organic framework to provide a recycled or repurposed metal-organic framework system.

Methods of synthesizing and recycling metal-organic framework systems

Sulfur-tolerant reforming catalysts that include bulk alumina in the catalyst support are provided. The sulfur-tolerant reforming catalysts can include a sulfur-tolerant catalytic metal to facilitate reforming. The catalyst can further include a support material that includes at least some alumina as bulk alumina and/or octahedrally coordinated alumina. The sulfur-tolerant reforming catalysts can be regenerated, such as periodically regenerated, under relatively mild conditions that allow the catalysts to maintain reforming activity in the presence of 1 vppm to 1000 vppm of sulfur in the feed for reforming.
