Abstract
A method and apparatus for dehydrating bio-1-alcohols to bio-1-alkenes with high selectivity. The bio-1-alkenes are useful in preparing high flashpoint diesel and jet biofuels which are useful to civilian and military applications. Furthermore, the bio-1-alkenes may be converted to biolubricants useful in the transportation sector and other areas requiring high purity/thermally stable lubricants.
Claims28
A bio-1-alkene product, comprising:
- at least one bio-1-alcohol;
- at least one desired catalyst, wherein said bio-1-alcohol is subjected and heated to at least one desired catalyst;
- and
- at least one purge gas which controls dwell time and temperature at a rate of about 0.01 to about 1.0 per mass of said catalyst/hour to produce bio-1-alkene product.
1 more element
A bio-1-alcohol dehydration catalyst, comprising:
- at least one inorganic solid support;
- a basic aqueous solution, wherein said inorganic solid support is subjected to a first treatment with said basic aqueous solution;
- at least one first inert gas or air, wherein said base treated inorganic solid support is dried under a heated stream of said air or said inert gas, wherein said first base treated inorganic solid support is treated with at least one organosilane diluted in at least one hydrocarbon solvent;
- and
- at least one second inert gas or air, wherein said second treated inorganic solid support is heated and dried under said second air or an inert gas.
