*2.3. Experimental Apparatus*

The designed reactor is a stainless steel cylindrical chamber with the inner diameter of 9 mm and the length of 300 mm. To control the reactor temperature, feed temperature, flow rate, and pressure, the setup was equipped by a jacket heater, heating blower, MFC model F-231M, made by Bronkhoest, pressure sensor model DP2-21 and backpressure regulator 1315G2Y, made by Hoke (prentice HALL, Upper Saddle River, NJ, USA), respectively. In the designed tests, the feed stream was supplied from industrial acetylene hydrogenation unit in Jam Petrochemical Complex. Table 2 shows the composition of the feed stream in the acetylene hydrogenation unit of Jam Petrochemical Complex.
