Upgrading of Syrian petroleum coke by pre-oxidation [PDF]
Solvent extraction offers a simple but generally ineffective approach to the desulphurization of high-sulphur petroleum coke where the organic sulphur compounds present may be selectively dissolved.

Desulphurization of petroleum coke
The sulphur content in coal and petroleum coke varies from traces to 10% or more by weight. The exists in two forms inorganic and organic. Sulfur in coal and rocks associated with coal mines like petroleum wastes can occur as organic sulfur, surfate ...

Demand Shocks, Export Diversification, and Firm Performance During the Great Trade Collapse
ABSTRACT This paper analyzes the impact of external demand shocks from the 2008 to 2009 Great Trade Collapse on the performance of Chinese exporters and examines how export diversification mitigates these effects. Using Chinese Customs data merged with financial data from all listed Chinese firms, we construct firm‐specific demand shocks based on pre ...

Pitch and petroleum coke additions to coke oven charges
Asphalt, pitches, solvent refined coal (SRC) and petroleum coke were added to coke oven charges in an attempt to make good metallurgical coke from Canadian coal of poor coking quality. Asphalt, pitches and SRC were added to a low fluid western Canadian coal of medium volatile bituminous rank, and the blends coked in a technical-scale moveable wall test

Estimating National and Foreign Trade Elasticities Using Generalized Transport Costs
ABSTRACT We introduce the definition of two distinct trade elasticities corresponding to imports from regions located in the same country (national elasticities) and foreign regions located in other countries (foreign elasticities). We resort to a three‐tier nested CES utility structure to derive the corresponding demand gravity equations.
