Dry Reforming of Methane Over Oil Palm Shell Activated Carbon and ZSM-5 Supported Cobalt Catalysts [PDF]

, 2017
In this study, cobalt supported oil palm shell activated carbon (Co/OPS-AC) and ZSM-5 zeolite (Co/ZSM-5) catalysts have been prepared for dry reforming of methane. Cobalt ratios of 6.0 and 14.0 wt% were deposited via wet impregnation method to the OPS-AC

Production of middle distillates through olefin oligomerization using ZSM‐5 as a catalyst

The Canadian Journal of Chemical Engineering, EarlyView.
Abstract The global transportation sector relies heavily on gasoline (C5–C12) and diesel (C11–C24), which together account for approximately 60% of its energy needs. Driven by rapid industrialization and urbanization, diesel consumption is outpacing gasoline, with projections estimating global demand by 2035 at 27 million barrels per day for gasoline ...

Characterizing early behavioral and social–emotional problems in young children with SCN1A+ Dravet syndrome: Findings from the ENVISION prospective natural history study

Epilepsia, EarlyView.
Abstract Objective Dravet syndrome (DS) is the prototypic developmental and epileptic encephalopathy, characterized by drug‐resistant seizures, developmental slowing, and many other morbidities. Detailed characterization of behavioral phenotypes and social–emotional skill development are limited.

Intraoperative Molecular Imaging Can Detect Large Nerve Perineural Invasion: A Case Report

Head &Neck, EarlyView.
ABSTRACT Background Perineural invasion (PNI) in head and neck squamous cell carcinoma (SCC) results in worse overall survival. Diagnosis requires resection and microscopic evaluation. Methods A 63‐year‐old male with persistent cT4aN0 p16‐positive SCC of the left base of tongue following chemoradiotherapy underwent salvage total glossectomy ...

Selective Hydrodemethylation of Methylalkylbenzenes on Potassium Hydride

Angewandte Chemie, Volume 138, Issue 6, 2 February 2026.
Selective catalytic hydrodealkylation of methylalkylbenzenes on carbon‐supported potassium hydride is reported. The reaction exhibits a reactivity trend of 1° ∼ 2° ∼ 3° < CH3, which is opposite to traditional dealkylation and hydrodealkylation. DFT calculations on the (001) facet of KH with ortho‐ethyltoluene suggest that selectivity is controlled by ...

Esterification process catalyzed by ZSM-5 zeolite synthesized via modified hydrothermal method

MethodsX, 2018
A modified hydrothermal method for ZSM-5 synthesis was described. The crystals gave a typical pattern (2θ at around 22.5°, 24.0° and 29.8° corresponding to the major peaks of (501, 303 and 503 crystal surfaces)), which indicated that the subnanocrystals ...
