A method is provided for fabricating a diol containing a bis-cycloaliphate. The diol is hydrogenated with hydrogen and a catalyst. Therein, the diol has a bis-aromatic. The catalyst comprises an active metal and a catalyst carrier. The active metal is a VIII-B-group transition element. The catalyst carrier is an oxide of IV-B-group element. Thus, the diol containing the bis-cycloaliphate is generated.

Alkylated aromatic products are produced in a process comprising the steps of pyrolysing a pyrolysable raw material in a pyrolysis process to obtain a pyrolysis product stream containing a phenolic product and aromatics products; separating the pyrolysis product stream into a first product stream containing phenolic products and a second product stream containing aromatics products; subjecting the first product stream to a hydrogenation reaction to hydrogenate the phenolic product to obtain an aliphatic alcohol; then reacting the aliphatic alcohol with the aromatics products in the presence of a transalkylation catalyst comprising a solid acid catalyst to form an alkylated aromatic product. The alkylated aromatic product may be subjected to further treatment such as hydroprocessing. The alkylated aromatics product may be used in the production of fuels from biomass.
