The bottom line is that President Bush was dead right last month to offer $1.7 billion to boost hydrogen technology, although it would help if the White House also promoted high-mileage hybrid cars for the present.
So far, its program to accelerate alternative and renewable fuels and technologies has invested more than $400 million in projects boosting hydrogen, biofuels, and electricity for transportation.
Environmental regulations imposed on transport fuels, especially specifications on sulfur and nitrogen content, generally boost hydrogen requirements in refining industries.
Besides, the ternary metals are supposed to generate synergistic effect to boost hydrogen evolution reaction (HER) properties of CoMoO-S/NF via sulfurization in the second step.
Argonne chemist Michael Krumpelt and his colleagues in the Chemical Engineering Division are using 'single-site' catalysts based on ceria or lanthanum chromite, doped with either platinum or ruthenium, to boost hydrogen production at lower temperatures during reforming.
The Dutch team postulates in Nature that an older massive star collided with a younger, smaller, hydrogen-rich star, which boosted its hydrogen content.
In this regard, the operating conditions of a radial-flow tubular membrane reactor (RF-TMR) are optimized via Differential Evolution (DE) method to boost the hydrogen and aromatic yields in catalytic naphtha reforming process.
We report the simultaneous reduction, surface modification, and stitching of graphene oxide (GO) by ethylenediamine (EDA) and triethylenetetramine (TET) to boost the hydrogen gas barrier performance of polyurethane (PU) composite-coated nylon films.
Further experiments on photocatalysis reveal the critical role of thermal treatment in terms of boosting photocatalytic hydrogen production almost 3-fold for all samples under full range irradiation (≥250 nm).
Such design not only enlarges the surface area to load catalyst but also induces perturbation to the liquid flow and shortens the transport length, which increases the active surface area and enhances the mass transfer and eventually boosts the hydrogen production rate.
