摘要:
A method includes brominating a butanes feed stream including i-butane in a bromination reactor to form a bromination effluent stream including t-butyl bromide. The method includes dehydrobrominating the t-butyl bromide to form isobutylene. Another method includes brominating a mixed pentanes feed stream including i-pentane and n-pentane in a bromination reactor to form a bromination effluent stream including t-pentyl bromide. The method includes dehydrobrominating the t-pentyl bromide to form isoamylene and HBr.

The invention relates to Cu-Al-Mn shaped catalyst bodies in extruded form, and to a process for their preparation. The shaped catalyst body is suitable for the hydrogenation of organic compounds containing a carbonyl function, in particular for the hydrogenation of aldehydes, ketones and carboxylic acids and/or their esters. In particular, the shaped catalyst body is suitable for the hydrogenation of fatty acids or their esters, such as fatty acid methyl esters, to form the corresponding alcohols and dicarboxylic acid anhydrides, such as maleic anhydride, or esters of di-acids and di-alcohols, such as butane diol.

This vehicle monitoring system provides a plurality of sensors in the vehicle recording performance of the vehicle. A processor (remote or on-board) receives data from the sensors. The processor classifies the data from the at least one sensor as an event in one of a plurality of classifications. The processor associates at least one parameter with the classification.

A method is provided for converting synthesis gas to liquid hydrocarbon mixtures useful as distillate fuel and/or lube base oil. The synthesis gas is contacted with a synthesis gas conversion catalyst comprising a Fischer-Tropsch synthesis component in an upstream catalyst bed thereby producing an intermediate hydrocarbon mixture containing olefins and C 21+ normal paraffins. The intermediate hydrocarbon mixture is subsequently contacted with a hydroisomerization catalyst and an olefin saturation catalyst, thereby resulting in a product containing no greater than about 25 wt% olefins and containing no greater than about 5 wt% C 21+ normal paraffins. The hydroisomerization and olefin saturation catalysts may be in separate beds or mixed in a single bed downstream of the synthesis gas conversion catalyst.

The invention relates to a catalyst composition comprising (a) a noble metal selected from the group consisting of platinum (Pt), palladium (Pd), rhodium (Rh), rhenium (Re), ruthenium (Ru) and iridium (Ir), (b) tin (Sn), (c) zinc (Zn), (d) alkaline earth metal and (e) a porous metal oxide catalyst support, wherein the amount of each of elements (a) - (d) is independently chosen in the range of from 0.1 to 5 wt.% based on the porous metal oxide catalyst support Furthermore, the invention also relates to a process for the preparation of said catalyst composition and its use in non-oxidative dehydrogenation of an alkane, preferably propane.
