Hydrogen Production via Acetic Acid Steam Reforming over HZSM-5 and Pd/HZSM-5 Catalysts and Subsequent Mechanism Studies

Acetic acid (HOAc) was selected as a bio-oil model compound for the steam reforming of bio-oil for hydrogen production. The influence of temperature and steam-to-carbon ratio (S/C) on the steam reforming of HOAc over hydrogen-type Zeolite Socony Mobil-5 (HZSM-5) and the catalyst with added Pd (Pd/HZSM-5) have been investigated in a fixedbed reactor. Brunauer–Emmett–Teller surface area measureme...

Hydrogen production by steam reforming of dimethyle ether over Cu/ZnO/Al2O3 and H-ZSM-5 catalysts: An experimental and modeling study

Hydrogen was produced by steam reforming of dimethyl ether (DME) using a physical mixture of commercial HZSM-5 zeolite (for DME hydrolyzing) and Cu/ZnO/Al2O3 (for methanol steam reforming) as a catalyst in a fixed bed reactor. The experiments were performed at atmospheric pressure and in a temperature range from 270 to 310 °C. The effects of feed temperature and gas hourly space velocity (GHSV)...

A unique microwave effect on the microstructural modification of Cu/ZnO/Al2O3 catalysts for steam reforming of methanol.

A short time (3-10 min) of microwave irradiation on the CuO/ZnO/Al2O3 oxide precursor can result in a unique tailored microstructural modification on the catalyst, leading to a significantly enhanced performance for H2 production from steam reforming of methanol.

Activity and deactivation studies for direct dimethyl ether synthesis using CuO-ZnO-Al2O3 with NH(4)ZSM-5, HZSM-5 or gamma-Al2O3

Herein we investigate the use of CuO-ZnO-Al2O3 (CZA) with different solid acid catalysts (NH4ZSM-5, HZSM-5 or γ-Al2O3) for the production of dimethyl ether from syngas. It was found that of the solid acids, which are necessary for the dehydration function of the admixed system, the CZA/HZSM-5 bifunctional catalyst with a 0.25 acid fraction showed high stability over a continuous period of 212 h...
