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.

Fischer-Tropsch process for the synthesis of hydrocarbons by bringing a feedstock including synthesis gas into contact with a catalyst prepared by the following: a porous support is brought into contact with a cobalt metal salt of which the melting point of the cobalt metal salt is between 30 and 150° C. for between 5 minutes and 5 hours, in order to form a solid mixture, the weight ratio of said cobalt metal salt to the porous oxide support being between 0.1 and 1; the solid mixture obtained is heated with stirring under atmospheric pressure at a temperature between the melting point of the cobalt metal salt and 200° C. for a period of time of between 30 minutes and 12 hours; the solid obtained is calcined at a temperature above 200° C. and below or equal to 1100° C.

Disclosed is a method for converting cymene generated from renewable low value terpene streams into renewable benzene, toluene, xylenes, and cymene isomers (ortho and meta) under flow disproportionation reaction conditions, which compounds are basic building blocks for fragrance materials. This technology has potential to replace high volume petrochemical-based feedstocks with plant-based building blocks that can fill the renewability gap for key fragrance ingredients.

Processes for converting one or more C.sub.1-C.sub.5 linear or branched alcohols to one or more C.sub.2-C.sub.5 olefins are provided. In one exemplary embodiment, the process can be a single stage process for the direct conversion of C.sub.1-C.sub.5 alcohols to olefinic mixtures (e.g., C.sub.2-C.sub.5) carried out in a reactor using a catalyst that includes zeolite doped with boron and phosphor. Systems for carrying out these processes are also provided.
