A pyrolysis method and system are provided that enhances the production of C3 and C4 alkanes in the resulting pyrolysis effluent. More particularly, the disclosed pyrolysis method and system may be configured to enhance the production of C3 and C4 alkanes due to the use of certain pyrolysis catalysts and more intense pyrolysis conditions.

Pyrolysis method and system for recycled waste

This invention is generally directed to a batch process for the preparation of cis-2,2,4,4-tetramethylcyclobutane-1,3-diol comprising:

Process for the preparation of cis-2,2,4,4-tetramethylcyclobutane-1,3-diol

Disclosed is a process for the isomerization of 2,2,4,4-tetraalkylcyclobutane-1,3-diols, such as 2,2,4,4-tetramethylcyclobutane-1,3-diol, by contacting the diol with a supported ruthenium catalyst in the presence of hydrogen at elevated pressures and temperatures. The process is carried under conditions in which there is no net production of 2,2,4,4-tetraalkylcyclobutane-1,3-diol. The process may be carried out in the presence or absence of a solvent and in the liquid or vapor phase.
