A method for converting an alcohol to hydrocarbons comprises two serially placed catalysts. The fraction of aromatics is reduced to desired levels. The method comprises: a) contacting the alcohol with a first catalyst on a carrier, said carrier is selected from a mixed oxide and a mesoporous carrier, said first catalyst comprises at least one basic oxide and optionally at least one selected from the group consisting of metals and metal oxides, then b) contacting the resulting mixture from step a) with a second catalyst wherein said second catalyst is an etched metal loaded zeolite catalyst wherein the etched metal loaded zeolite catalyst is manufactured with a method comprising etching with subsequent loading of metal onto the catalyst, wherein the metal is in the form of nanoparticles, and wherein at least two different metals are loaded onto the etched zeolite catalyst. The hydrocarbons are recovered and used for instance for fuel including gasoline, kerosene, diesel, and jet propellant, and jet fuel. Naturally, other uses of hydrocarbons should not be excluded.

According to one or more embodiments described herein, a method for dehydrogenating hydrocarbons may include passing a hydrocarbon feed comprising one or more alkanes or alkyl aromatics into a fluidized bed reactor, contacting the hydrocarbon feed with a dehydrogenation catalyst in the fluidized bed reactor to produce a dehydrogenated product and hydrogen, and contacting the hydrogen with an oxygen-rich oxygen carrier material in the fluidized bed reactor to combust the hydrogen and form an oxygen-diminished oxygen carrier material. In additional embodiments, a dual-purpose material may be utilized which has dehydrogenation catalyst and oxygen carrying functionality.

The present invention is generally directed to the production of low-carbon syngas from captured CO.sub.2 and renewable H.sub.2. The H.sub.2 is generated from water using an electrolyzer powered by renewable electricity, or from any other method of low-carbon H.sub.2 production. The improved catalysts use low-cost metals, they can be produced economically in commercial quantities, and they are chemically and physically stable up to 2,100° F. CO.sub.2 conversion is between 80% and 100% with CO selectivity of greater than 99%. The catalysts don't sinter or form coke when converting H.sub.2:CO.sub.2 mixtures to syngas in the operating ranges of 1,300-1,800° F., pressures of 75-450 psi, and space velocities of 2,000-100,000 hr.sup.−1. The catalysts are stable, exhibiting between 0 and 1% CO.sub.2 conversion decline per 1,000 hrs. The syngas can be used for the synthesis of low-carbon fuels and chemicals, or for the production of purified H.sub.2. The H.sub.2 can be used at the production site for the synthesis of low-carbon chemical products or compressed for transportation use.
