A process that can enrich highly contaminated natural gas has been developed at Eindhoven University of Technology (Netherlands; edlinks.che.com/6891-531), with support from the Royal Shell/Dutch Group. The device shows promise as a way to utilize the large quantities of natural gas that is currently unusable because of high concentrations of carbon dioxide and hydrogen sulfide. Existing technology, such...

Up to now, light-cycle oil (LCO) produced from desulfurized vacuum-gas oil has been used as a base for heavy oil or for blending with straight gas oil (SGO). But a decreasing demand for heavy oil, combined with LCO’s drawbacks as a blending material (such as low cetane number), is drying up these outlets for LCO. Furthermore, existing technology for hydrotreating LCO is energy intensive and consumes...

Exelus Inc. (Livingston, N.J.; edlinks.che.com/6891-533) has demonstrated the performance of its ExSact solid-acid alkylation process, having achieved over 1,000 hours of pilot-plant operation on an untreated MTBE raffinate feedstock. The pilot-plant testing was performed to prove the robustness of the ExSact catalyst to common feedstock poisons, such as oxygenates, diolefins and nitriles, to furnish the...

Although there has been big surge in biodiesel production recently, such fuels are not without problems of their own, such as low mileage, poor performance at lower temperatures, and adverse effects on engine components. Also, the production process for making biodiesel — the methyl esterification of fatty acids derived from vegetable oils (such as palm and rapeseed)...

    The dramatic jump in petroleum and natural gas prices over the recent years has created much impetus to reduce operating costs at chemical process plants. In processes that use either oil or gas for feedstock, such reduction can come either from improved energy-usage methods or from yield improvements. In either case, the plant's steam resource is often a primary provider of heat or...
