n-butane isomerization
Thread Content
Experts, what are the factors that affect the activity of isomerization catalysts? I need experts’ advice! ! ! !
Is GTC a catalyst from a certain company? Different ones are not the same
For platinum catalysts, the most critical factor is water, which causes permanent deactivation. It can be regenerated after inactivation due to sulfur poisoning
What is isobutane used for once it’s produced? ?
It can be used as a raw material for isobutane dehydrogenation, and it can also be used as a raw material for alkylation
Butane isomerization catalysts are precious metal catalysts that use aluminum oxide as a carrier and platinum as the active component; they can maintain high activity in acidic (chlorine) environments. They are highly sensitive to water, as water reacts with aluminum chloride to produce aluminum hydroxide, which gives an alkaline environment and leads to the permanent inactivation of the acidic sites on the catalyst. Secondly, components with a molecular weight of C5 or higher will occupy the active channels in the catalyst, reducing its reactivity. Sulfur, chlorine, and other substances will accumulate on the catalyst, leading to a gradual decline in its activity; this accumulation can be removed through thermal hydrogen stripping. The accumulation of carbon can result in charring; this is provided for reference only
Isn’t it better to directly subject n-butane to ethylene cracking, rather than isomerizing it first and then carrying out alkylation? ?
The premise is that both sets of systems need to utilize butane isomerization, which requires less investment and is suitable for areas and facilities where there is a limited supply of n-butane. Ethylene cracking is not a process that can be implemented easily
Our company has ethylene cracking units; in that case, it would be more appropriate to use butane for ethylene cracking, right? ?
At the moment, pyrolysis is a suitable option, provided that your pyrolysis furnace is designed for the pyrolysis of light hydrocarbons. In China, steam cracking typically uses naphtha, with some facilities possibly having 1-2 light hydrocarbon cracking units. The yield of trienes from n-butane cracking is relatively high
