ABSTRACT:

An analytical method for determination of feed component concentration in the product stream has been worked on for the past four months. In the work done by Smith (1982) there was greater than 98% conversion of the feed to products. However, in taking data useful to determine kinetic parameters it is necessary to accurately determine the conversion. Decanal and decanol seem to have non-linear relative response factors and therefore present a problem in analyzing the products. A calibration curve will be used to determine the appropriate relative response factors for decanol and decanal. The non-linearity is believed to be caused by the column not fully desorbing the oxygenated compounds. Qualitative runs using heptane, decane, decanal, and decanol have shown that contact times between one and ten seconds will be sufficient to obtain conversions from 5% to 95%. These runs were made at 650 K and 1 atm using 0.08 gm of Ni-ZSM-5 bound in Ludox binder. The low pressure was used because we have had difficulty in reaching steady state at low flow rates and high pressure. The back pressure regulator did not work well at low flow rates.  However, there is reason to believe that steady state operation and therefore good material balances can be achieved at an operating pressure of 200 psig when higher flow rates are used. Therefore, we propose to run at the highest pressure, up to 200 psig, that we can close the material balances. The effects of pressure will be examined by running at different pressures but the same contact time. (ERA citation 10:012629)
