You can submit a Cantera Python script (test.py) in batch mode with the following command: 

bsub [LSF options] "python test.py"

Here you need to replace [LSF options] with LSF parameters for the resource requirements of the job. Please find a documentation about the parameters of bsub on the wiki page about the batch system.
