The reaction consists of several steps such as the dehydrogenation of light alkanes, the oligomerization of alkenes, the dehydrogenation of cycloalkanes, and so on. And it is widely accepted that the Bronsted acid sites of zeolite provide the catalytic sites for oligomerization and Ga species are ...
According to this mechanism, alkanes and alkenes are predicted to be primary products, as is observed experimentally (91). Moreover, oxygen-containing compounds are predicted to be primary products formed via CO insertion, as discussed in Section 2.1. Sign in to download full-size image Scheme ...
Chemical reaction, e.g. for partial oxidation of alkanes into alkenes, uses regenerative heat exchanger containing bed of catalyst particles for alternate reaction mixtures to flow throughThe reaction is carried out using a regenerative heat exchanger (1) with at least one compartment (2, 3) ...
HC HC HC C H ORGANIC REACTION MECHANISMS 9 Although the hydrogen atoms are transferred one at a time, the reaction is fast enough that both of the atoms usually end up on the same side of the CPC double bond. This can't be seen in most alkanes produced by the reaction because of ...
It has been well documented that TEMPO can serve not only as a radical scavenger but also as an oxidant in transition-metal catalysis44,45. Thus, we continued to test several other oxidants, such as K2S2O8 and 2,3-dichloro-5, 6-dicyano-1,4-benzoquinone (see Supplementary Table 1 for...
Alkenes undergo addition reactions, adding such substances as hydrogen, bromine, and water across the carbon-to-carbon double bond. What type of reaction do alkynes undergo? The principal reaction of the alkynes is addition across the triple bond to form alkanes. These addition reactions are analog...
alkynes react with dihydrogen in the presence of catalysts such as pt/pd/ni in order to form alkenes. the alkenes formed, further react with dihydrogen to form alkanes. it has been observed that in most reactions triple bond is converted into double bond and double bond is then converted ...
FTprocess tail gas contains CO, H2, C1-C4 light alkanes, and a small amount of heavy alkanes. There are three ways to treat this tail gas. 1) The tail gas is fully burnt as fuel ingas turbinesforpower generationor in boilers for very high pressure (VHP) steam generation in the utilit...
The participation of unsaturated alkenes that were formed on the metal sites was evident from the strong resemblance between the product distributions obtained from n-dodecane hydrocracking over a Pt/SiO2 physically mixed with an acid silica-alumina, and from 1-dodecene cracking over, exclusively, ...
