To facilitate value-added chemical production from renewable glycerol, gas-phase glycerol dehydration to acrolein was conducted using supported silicotungstic acid as solid catalysts, focusing on the effects of mesoporous catalyst supports catalytic performance. One alumina (Al) support with average mesopore size 30 nm and two silica (Si1254 Si1252) 6 11 nm, respectively, were comparatively eva...

The polycyclic aromatic hydrocarbon (PAH) pollution process in mining areas, particularly coal has accelerated because of chemical production and gangue accumulation. In this study, PHAs concentrations surface soil was determined via gas chromatography–mass spectrometry. composition, spatial distribution sources PAHs were analyzed, their potential carcinogenic risks evaluated.Results showed a w...

Environmental performance is extremely vital for sustainable growth in China, and the impact of a regional integration policy plays an important role improving environmental performance. However, current studies are weak causal inference, firm-level evidence lacking. As result, taking Outline Pearl River Delta Reform Development Plan as quasi-natural experiment, with propensity score matching d...
