摘要： PROBLEM TO BE SOLVED: To provide a producing method for a synthetic gas from heavy natural gas, by which supply energy necessary in a reforming tube inside a heating furnace is decreased. SOLUTION: This producing method for the synthetic gas from the heavy natural gas is performed by mixing light natural gas, which is obtained by the reaction of desulfurized heavy natural gas with steam, with steam and pre-heating, bringing the mixture into contact with a catalyst under an adiabatic condition at 500-700 deg.C to carry out a 1st stage reforming reaction, and next, carrying out a 2nd stage reforming reaction in the reforming tube inside the heating furnace. A catalyst prepared by incorporating a specific quantity of Ni or a platinum group metal as an active ingredient in a support comprising CaO and Al2 O3 , containing a specific quantity of CaO, at least a part of which forms a compound with Al2 O3 , and having a specific porosity, or a catalyst prepared by incorporating specific quantity of Ni in α-alumina having a specific fine pore volume and composed of 98 wt.% aluminum oxide is used.

SOLUTION: This producing method for the synthetic gas from the light natural gas is performed by mixing desulfurized light natural gas with steam and pre-heating, bringing the mixture into contact with a catalyst under an adiabatic condition at 500-750 deg.C to carry out a 1st stage reforming reaction, and next, carrying out a 2nd stage reforming reaction in the reforming tube inside the heating furnace. A catalyst prepared by incorporating a specific quantity of Ni or a platinum group metal as an active ingredient in a support comprising CaO and Al2 O3 , containing a specific quqntity of CaO, at least a part of which forms a compound with Al2 O3 , and having a specific porosity or a catalyst prepared by incorporating a specific quantity of Ni in α-alumina having a specific fine pore volume and composed of >=98 wt.% aluminum oxide is used.

摘要： PURPOSE:To prevent rise of temperature for a pressure resistant vessel by making the produced gas which is flowed out ultimately from a catalytic layer to be exchanged thermally with a heat exchanger for gaseous starting material at low temp. which is flowed into the first catalyst layer and enabling gas to be cooled thereby. CONSTITUTION:A catalyst is packed in the space which is sandwiched between two cylindrical catalyst supporters 7, 8 having different diameter and gas permeability to form a catalyst layer 6, and the produced gas which is flowed out ultimately from the catqlyst layer 6 is exchanged thermally with a heat exchanger 4 for gaseous starting material at low temp. which is flowed into the first catalyst layer and thereby gas is cooled and passed along the inner surface of a pressure resistant outside shell 1. The cooling liquid is supplied through a supply path 22 penetrating an above cover 2 to the bottom end of a cooling pipe 15 from the outside of reactor and the vapor of cooling liquid or the mixture of vapor and liquid is conducted out through a conduction path 23 penetrating cover 2 to the outside of reactor from the above end of the cooling pipe 15. Thus, the rise of temp. for the pressure resistant vessel can be prevented efficiently.

摘要： PURPOSE:To effect a reaction at favorable efficiency with a relatively simple construction, by a method wherein a heat exchanger is provided at the center of a reaction vessel, and reactant gases are passed alternately through a plurality of catalyst beds provided in an annular space between the heat exchanger and the reaction vessel. CONSTITUTION:Raw material gases are introduced through a raw material gas inlet 12, are fed into the tube side of the heat exchanger 6 from a lower part thereof, and are passed to an upper part. Then, the raw material gases are fed into the first catalyst bed 5 from outside, are passed through the inside in substantially radial directions, and are fed into the first shell side of the heat exchanger 6, where the gases are cooled by the inlet raw material gases, and are fed into the second catalyst bed 5. Similarly, the gas is passed alternately through the catalyst layer 5 and the heat exchanger 6, and the reaction gas is discharged to the exterior of the reaction vessel 1 through a reaction gas outlet 13. Cooling gases are fed to reaction gas outlets of the heat exchanger 6 to finely adjust the gas temperature at the inlet to the catalyst bed 5, thereby maintaining the optimum temperature.
