Provided is an operation management system configured to manage delivery of a raw material from a raw material production base where the raw material including a hydride is produced to a plurality of dehydrogenation bases where the raw material is subjected to a dehydrogenation reaction to obtain a hydrogen-containing gas. The operation management system includes: an information acquisition unit configured to acquire first information on a dehydrogenation status in the plurality of dehydrogenation bases; and a delivery plan creation unit configured to create a delivery plan for delivering the raw material to the plurality of dehydrogenation bases on the basis of the first information.

Pathways are disclosed for the production of liquefied petroleum gas (LPG) products comprising propane and/or butane, and in certain cases renewable products having non-petroleum derived carbon. In particular, a gaseous feed mixture comprising CO.sub.2 in combination with CH.sub.4 and/or H.sub.2 is converted by reforming and/or reverse water-gas shift (RWGS) reactions, further in combination with LPG synthesis. A preferred gaseous feed mixture comprises biogas or otherwise a mixture of CO.sub.2 and H.sub.2 that is not readily upgraded using conventional processes. Catalysts described herein have a high activity for reforming (including dry reforming) of CH.sub.4, as well as simultaneously catalyzing RWGS. These attributes improve the management of CO.sub.2 that is input to the disclosed processes, particularly in those utilizing recycle operation to increase overall CO.sub.2 conversion. Economics of small scale operations may be improved, if necessary, using an electrically heated reforming reactor in the first or initial reforming stage or RWGS stage.

Chemical processors are configured to reduce mass, work in conjunction with solar concentrators, and/or house porous inserts in microchannel or mesochannel devices made by additive manufacturing. Methods of making chemical processors containing porous inserts by additive manufacturing are also disclosed.
