The present invention provides a process for the production of THF and 1,4-BDO from furan in the presence of a catalytic composition, wherein the catalytic composition contains at least one metal selected from the group consisting of Fe, Ru, Os, Co, Rh, Jr, Ni, Pd, Pt and, optionally, contains one or more additional metal on a solid support, and wherein said process comprises the steps of: i) contacting furan with hydrogen and water in a reactor in the presence of said catalytic composition for a time; ii) stopping the flow of furan and the flow of water to the reactor and removing furan and water from the reactor; iii) subjecting the catalytic composition to a gas stream comprising hydrogen at a temperature of from 200 to 600&#xb0; C. in the absence of the furan and water; iv) re-starting the flow of furan and the flow of water to the reactor.

A gasoline composition containing in the range of from 0.1 to 30 wt % alkylfurfuryl ether with an alkyl group having 1 to 4 carbon atoms is provided. The gasoline composition is prepared by blending the alkylfurfuryl ether in a gasoline base fuel. The alkylfurfuryl ether is prepared by reacting an alkyl alcohol having in the range of 1 to 4 carbon atoms is reacted with furfuryl alcohol by contacting a liquid phase comprising the alkyl alcohol and furfuryl alcohol with an acidic zeolite catalyst at a temperature in the range of from 50 to 200&#xb0; C.

A process is provided for manufacture of branched carboxylic acids from branched olefins by means of reaction with carbon monoxide and a solid acid catalyst. In this process, a branched olefin, or a precursor thereof, is reacted in continuously backmixed reactor, with continuously supplied carbon monoxide and water, while continuously an effluent is withdrawn comprising branched carboxylic acid, non-converted olefin, carbon monoxide and water, in the presence of an acidic ion exchanger, having sufficient acid groups to provide requisite protons for conversion of the olefin or a precursor of it, and carbon monoxide into branched carboxylic acids.
