Convert (html to pdf), Concatenate, Batch (Windows). AcrobatDC?

I've been assigned the duty of researching a method to handle pdfs in batch mode (for windows OS).   What needs to be done is to mass convert HTML files into PDF files, then concatenate multiple pdfs into one.   This needs to be done in a command line.

I've been told that AcrobatDC is the product to look at.   Is acrobatDC the right product, or do you have or recommend another product?

If Acrobat DC can do only one of these functions, I can look at another product to handle the other.   But it has to be done in batch.   I've downloaded an adobe trial and have yet to use it - hope the trial includes AcrobatDC.
