The invention relates to a cyclic method of producing a hydrogen rich and/or a carbon monoxide rich stream using different materials, a first solid material, a second solid material and a CO.sub.2 sorbent material.

In a first step a first gas stream comprising steam and at least one reductant is brought in contact with the three materials resulting in a hydrogen rich outlet stream.

In a second step, the captured CO.sub.2 from the first step is released and converted to CO to produce a CO rich outlet stream.

The invention further relates to an installation for producing a hydrogen rich and/or carbon monoxide rich stream.

The invention relates to a cyclic method for capturing and utilizing CO.sub.2 contained in a gas stream. The method uses three different materials, a first solid material, a second solid material and a CO.sub.2 sorbent material.

In a first step a first gas stream comprising CO.sub.2 and at least one reductant is brought in contact with the three materials, resulting in an outlet stream comprising water. In a second step, the captured CO.sub.2 from the first step is released and converted to CO to produce a CO rich outlet stream. The invention further relates to an installation for capturing and utilizing CO.sub.2.

The invention describes a mass for scavenging mercaptans which is particularly suitable for the treatment of olefinic gasoline cuts containing sulfur such as gasolines resulting from catalytic cracking. The scavenging mass comprises an active phase based on group VIII, IB or IIB metal particles which is prepared by a step of bringing a porous support into contact with a metal salt of said group VIII, IB or IIB metal and a step heating the resulting mixture to a temperature above the melting point of said metal salt. The invention also relates to a process for using said scavenging mass for the adsorption of mercaptans.
