Abstract:The recent shale gas boom has transformed the energy landscape of the United States. Compared to natural gas, shale resources contain a substantial amount of condensate and natural gas liquids (NGLs). Many shale basin regions located in remote areas are lacking the infrastructure to distribute the extracted NGLs to other regions-particularly the Gulf Coast, a major gas processing region. Here we present a shale gas transformation process that converts NGLs in shale resources into liquid hydrocarbons, which are easier to transport from these remote basins than NGL or its constituents. This process involves catalytic dehydrogenation followed by catalytic oligomerization. Thermodynamic process analysis shows that this process has the potential to be more energy efficient than existing NGL-to-liquid fuel (NTL) technologies. In addition, our estimated payback period for this process is within the average lifetime of shale gas wells. The proposed process holds the promise to be an energy efficient and economically attractive step to valorize condensate in remote shale basins.

“…A c c e p t e d M a n u s c r i p t 4 Currently, extensive researches have been devoted to the modeling study of catalytic cracking of hydrocarbons over zeolite catalysts like HZSM-5 [3,6,9,13], such as the mechanistic modeling of the catalytic cracking of n-heptane [6], the micro-kinetic modeling of propane aromatization [9], the kinetic modeling of catalytic cracking of paraffinic surrogate [3] and so on. However, to our knowledge, the modeling study of catalytic cracking of hydrocarbons over Pt catalysts is still lacking.…”

“…Owing to the high Brønsted acidity and shape selectivity, zeolites are used extensively for the cracking of alkanes to yield low-molecular-weight alkanes and alkenes in the processing of petroleum, and the involved mechanisms have been widely studied theoretically and experimentally [6][7][8][9][10][11][12][13]. Noble metals, such as Platinum (Pt), Palladium (Pd), and Rhodium (Rh) are used as catalysts in many heterogeneous catalytic reactions for its excellent activity, selectivity and stability [14].…”

Non-oxidative methane aromatization by bimetallic (La, Co, Pd and Pt) M-Zn/HZSM-5: Impact of propane addition

et al. 2018

The non-oxidative aromatization of methane was studied over M-Zn/HZSM-5 (M=La, Co, Pd, and Pt) catalysts using propane as a co-reactant. The catalysts were characterized by BET, SEM, NH 3 -TPD and XRD techniques. Catalytic tests were performed in a fixed-bed reactor at 823 K, using a mixture of methane, propane, and nitrogen with ratio of 6/1/1.3, respectively. Propane conversion was above 50% and remained stable in the first 12 hours on stream; however, the methane conversion rapidly dropped from a high of about 10% to zero within 4 hours, implying  Tel:+982144787100(ext.3504); Fax:+982144787505;; p.bijani@aut.ac.ir 2 the absence of a stoichiometric reaction between the reactants. Both zinc and the second metal (M) had a beneficial effect on aromatic selectivity and Pt-Zn/HZSM-5 exhibited the highest aromatic yields and catalyst stability. The results of the present study showed that co-feeding of methane with propane cannot successfully induce methane to participate in aromatization reactions.
