Regulation Through Revelation: The Effect of Pollution Monitoring on Labour Demand

Business Strategy and the Environment, EarlyView.
ABSTRACT This paper investigates how manufacturing firms respond to a real‐time pollution monitoring programme, with a focus on the implication for employment. Contrary to the conventional expectation that environmental regulations negatively impact business, the findings reveal that enhanced pollution monitoring has a significant and robust positive ...

A study of the porosity of nuclear graphite using small-angle neutron scattering [PDF]

, 2013
Small angle neutron scattering (SANS) measures porosity in nuclear graphites, including both open pores, caused by escaping decomposition gases, and internal cracks (in coke particles) generated by anisotropic thermal contraction along the c-direction ...

On the Influence of Catalyst Mesopore Structure in the Catalytic Cracking of Polypropylene

ChemistryEurope, EarlyView.
Catalytic cracking is a promising approach to convert polyolefin plastics into hydrocarbons. Herein, the effect of catalyst pore size in polypropylene cracking using amorphous silica–alumina with identical external acidity, but varying mesopore diameters and particle sizes, is isolated. Mesopore size has minimal effect on activity, indicating that high

Coke Decomposition Kinetic Model of Spent Hydrodesulfurization Catalysts [PDF]

Journal of Applied Sciences and Nanotechnology
Recycling residue hydrodesulfurization (HDS) catalysts is essential due to frequent deactivation. Petroleum coke's high ignition temperature and complex combustion behavior stem from its graphite-like structure and low volatile matter.

A study of Ni‐Co/CeO2 catalyst derived from metal–organic framework for dry reforming of methane

The Canadian Journal of Chemical Engineering, EarlyView.
Abstract The efficacy of cobalt‐doped, MOF‐derived catalysts for dry reforming of methane (DRM) was examined. The focus was on the influence of varying nickel and cobalt molar ratios on catalytic performance. Three catalysts with Ni:Co ratios of 1:1, 1:0.5, and 0.5:1, were synthesized and tested with cerium oxide as a constant support. The DRM reaction
