Abstract:
A method of producing at least one derivate of a carboxylic acid. The method includes reacting a carboxylic acid with an auxiliary alkanol on a first catalyst to form a produced ester. A fraction of the produced ester is optionally separated to form a first separated ester. At least a fraction of said produced ester is reacted with hydrogen on a second catalyst to produce a mixture of product alkanol, auxiliary alkanol and optionally residual ester. The product alkanol is separated from the auxiliary alkanol in the mixture to form separated product alkanol, separated auxiliary alkanol, and optionally a second separated ester. The separated auxiliary alkanol is recycled to the reaction. Methods and catalysts for converting alcohols and acids to hydrocarbon jet and diesel fuels are also described.

Claim (Index 1):
A method for the production of at least one derivate of a carboxylic acid RCOOH, comprising\n (i) reacting in a reactor a carboxylic acid RCOOH with an auxiliary alkanol R\u2032OH on a first catalyst to form a produced ester RCOOR\u2032; (ii) optionally, separating a fraction of said produced ester RCOOR\u2032 to form a first separated ester RCOOR\u2032; (iii) reacting in said reactor at least a fraction of said produced ester RCOOR\u2032 with hydrogen on a second catalyst to produce a mixture comprising a product alkanol RCH 2 OH and said auxiliary alkanol R\u2032OH and optionally residual ester RCOOR\u2032; (iv) separating said product alkanol RCH 2 OH and said auxiliary alkanol R\u2032OH from said mixture to form separated product alkanol RCH 2 OH, separated auxiliary alkanol R\u2032OH and optionally a second separated ester RCOOR\u2032; and (v) recycling said separated auxiliary alkanol R\u2032OH to said reactor; wherein R and R\u2032 denote alkyl and/or aryl groups, and steps (i) and (iii) are conducted in said reactor concurrently.
