Abstract The Gulf countries have shifted to a new development paradigm, pursuing economic diversification by constructing special zones (SEZs). By investing overseas, China has been involved in the of SEZs region, especially since proposed Belt and Road Initiative (BRI). In this chapter, through analytical framework New Structural Economics (NSE), I examine three projects Chinese investments re...
In recent years, Jilin’s FDI(foreign direct investment) has grown faster, the amount of investment has been increasing, investing industries have presented variety, investing districts have been a steady expansion. Jilin province fostered a lot of powerful and large-scaled enterprise groups in three pillar industries--automobile industry, petrochemical industry and agricultural products process...
This survey aimed to evaluate the level of lead (Pb) pollution in cattle in the vicinity of the Shiraz oil and petrochemical industries using hair samples. Dairy farms located within 10 km of the Shiraz oil and petrochemical industries were identified and divided into four groups. Farms that were located in the radial zones of 0.5-1.5 km, 1.5-5 km, 5-7 km, 7-10.5 km were considered as groups A,...
Phenolic derivatives are used as raw materials in textiles, pulp and paper, petrochemical, pharmaceutical, oil-refineries and leather industries. These heterocyclic aromatic chemicals are among the most frequently found pollutants in industrial effluents. Since these compounds are toxic either through ingestion, inhalation or contact even at low concentrations, biodegradation of the effluent is...
The new spherical sol-gel hybrid material SiliaCat Pd0 selectively mediates the hydrogenolysis of aromatic alcohols, aldehydes, and ketones by using an ultralow catalytic amount (0.1 mol % Pd) under mild reaction conditions. The broad reaction scope as well as the catalyst's superior activity and pronounced stability open the route to green and convenient reductive deoxygenation processes of pr...
Hydride gases, such as phosphine and arsine, are important contaminants in process chemicals used in both the petrochemical and semiconductor industries. For example, the presence of phosphine, arsine, hydrogen sulfide and carbonyl sulfide in polymer grade ethylene or propylene can have a deleterious effect on catalysts used in the production of polypropylene plastics. Accurate data on the conc...
