Hydrogen-rich gas production from rice husk via steam gasification and catalytic reforming using CeO2-modified Ni-CaO absorption bifunctional catalysts synthesized by sol-gel method in a two-stage system was investigated. The results show that the Ce0.7Ni1Ca5 catalyst achieves maximum H2...

The firm-level approach to intraindustry trade reveals that the variation in the number of exporters or exported varieties (extensive margin) accounts for a greater share of the changes in aggregate trade than the variation in the average exports per firm variety (intensive margin). This paper...
