A method of preparing a catalyst precursor comprising:
- depositing a solution or suspension comprising at least one catalyst metal precursor and a polar organic compound onto a catalyst support, wherein the solution or suspension contains little or no water;
- if necessary, drying the catalyst support onto which the solution or suspension has been deposited;
- and
- calcining the catalyst support onto which the solution or suspension has been deposited to convert at least part of said catalyst metal precursor to its carbide.
