Synthesis of Cresols and Xyenols from Benzene and Methanol

    Research output: NRELTechnical Report


    This is the second of two reports that compare the manufacture of cresols and xylenols using two processes--a conventional catalytic process and a solar photothermal catalytic process--to determine the relative process economics. This report presents results of a process evaluation for the photothermal catalytic process. (The first report, Synthesis of Cresols and Xylenols from Phenol andMethanol, evaluates the conventional catalytic process.) An arbitrary base case plant size (fresh feed) of about 7.06 million kg/y (15.6 million lbm/y) was chosen and then scaled to a breakeven size. The evaluation indicates that the breakeven capacity is only about 24% of the base case and about the same percentage of the conventional catalytic process evaluated in the first report. Assumingthe total capital cost would double, which is unlikely, when the solar equipment is included, the overall conclusion in favor of the photocatalytic process would not change.
