HERSTELLUNGSVERFAHREN VON SYNTHESEGAS. |
摘要 |
Prodn. of an organic cpd. from a hydrocarbon-contg. feedstock comprises: (a) dividing the feedstock into 2 fractions; (b) subjecting the 1st fraction to primary steam reforming by mixing with steam and heating the mixt. by indirect heat exchange in presence of a reforming catalyst, to form an H2-contg. gaseous effluent at 650-850 deg.C; (c) mixing the effluent gas from (b) with the 2nd fraction from (a); (d) reacting in a single stage the gas mixt. from (c) with an O2-rich gas in a secondary reformer operating essentially adiabatically and contg. a single catalyst bed, to give a syngas at 850-1250 deg.C contg. a % CH4 equivalent of less than 1/10th of that of the gas mixt. from (c) and with a z ratio of 0.80-1.00 (z = moles H2/(2(moles CO) + 3(moles CO2))); (e) mixing the effluent gas from (d) with a H2-rich stream to form a final syngas stream; (f) injecting the final syngas into a synthesis loop, forming organic cpds. therein, and extracting a purge gas stream therefrom; (g) physically sepg. the purge gas stream into a H2-rich stream and a residual gas stream; and (h) recycling at least part of the H2-rich stream to step (e).
