This month’s Business Trends focuses on five major trends affecting the downstream industry. These include: a forecast on global demand for industrial valves to 2020, how the approval of Chinese teapot refinery crude import licenses could lead to a fuel supply glut, the surge in US ammonia and urea plant construction, the start of Nigeria’s DSDP program and the consolidation of Japan’s refining industry. © 2015 Hydrocarbon Processing.

In this study, boehmite sols were used as alumina precursors for preparing mesoporous γ-aluminas by two different methods. In one case polyethylenimine was used as a structure-directing agent, and in another case ultrasound treatment was applied. Nitrogen physisorption showed that aluminas that had been prepared by these methods demonstrated different porous structures. The sample obtained without additional treatment had closely packed spherical particles and pores had ink-bottle neck morphology. Ultrasound treatment led to the transformation of ink-bottle pores into cylindrical form and to the increase in surface area and pore volume. Aluminas prepared using polyethylenimine as a template showed larger cylindrical wormhole-like mesopores with a broader pore size distribution, high surface area and pore volume. Catalytic tests showed that textural properties as well as crystallite size were very important parameters of synthesized samples which affected the catalytic activity in the methanol dehydration reaction. It was found that γ-Al 2O3 prepared by ultrasound treatment had large crystallite size and demonstrated high catalytic activity. © 2010 Springer Science+Business Media, LLC.

On mixing acetone solutions of 4,5-dichloro-2-dichloromethylen-4-cyclopenten-1,3-dione with thiourea or its homologs clear yellow amorphous hygroscopic precipitates were formed practically quantitatively and instantaneously, which are probably the predicted half a century ago Möbius aromatic compounds. © 2010 Springer Science+Business Media, Inc.
