yes, I know, the answer would be "why don't you install TomEE directly?", but the only web server approved of the company is Tomcat 8.5 and I want to know if there is some way to convert my tomcat server to TomEE "manually" installing the required libs and dependencies or some plugin in the server. I have to migrate applications running in Liberty to Tomcat and the last one doesn't support thing like EJBs, JPA, JTA, JAX-RS etc.

TomEE offers a drop-in war archive, which can be used to enhance a Tomcat with the TomEE capabilities.
The TomEE documentation has some information about the installation procdere as well as about the drawbacks of such an approach.
However, the drop-in war approach is subject of removal in later versions of TomEE. The last drop-in war releases are 7.1.4 and 7.0.9, which are EE7. If you want to have EE8, you are stuck with 8.0.6 as the drop-in war approach was dropped in later releases.
Regarding the Tomcat version:
- 8.0.x is build upon Tomcat 9.0.x
- 7.1.x is build upon Tomcat 8.5.x
- 7.0.x is build upon Tomcat 8.5.x
The TomEE drop-in war should match the related Tomcat version (as mentioned above), i.e. if you have a Tomcat 8.5.x in your company, you can only get EE7 capabilities from the drop-in war archive.
