A method of producing a fuel additive includes passing a feed stream comprising C4 hydrocarbons through a methyl tertiary butyl ether unit producing a first process stream; passing the first process stream through a selective hydrogenation unit producing a second process stream; passing the second process stream through an isomerization unit producing a third process stream; and passing the third process stream through a hydration unit producing the fuel additive and a recycle stream.

The present disclosure relates to a catalyst composition comprising copper and iron on a support for use in a process for the synthesis of higher alcohols from a syngas feed stream comprising hydrogen and carbon monoxide, the catalyst composition being remarkable in that the support is one or more zeolite, in that the total content of iron and copper is ranging from 1 to 10 wt. % based on the total weight of the catalyst composition and as determined by inductively coupled plasma optical emission spectroscopy, in that the Cu/Fe bulk molar ratio is ranging from 1.1:1.0 to 5.0:1.0 as determined by XRF spectroscopy.

The present invention relates to an integrated process that allows the production of tert-butyl ethers of glycerol, used as a high boiling point solvent (HBPS) in paint formulations (water-based) and cleaning products, or a stream of isooctenes to be used as an octane in the gasoline pool, in a simple way, just directing the flow through the areas necessary for the conversion and separation of the process and using the same equipment, aiming at gains in process yield (maximization of glycerol and isobutene conversions) and minimizing investment and operating costs. In view of this, there is a unit flexibility in producing different high added value products.

The present invention discloses an integrated process and an apparatus for production of various alcohols and Oligomerization of Olefinic feed stocks comprising butylenes and mixture thereof. In this process the combined light olefinic hydrocarbon feedstock is divided into two streams and contacted in two different reaction zones, viz. hydration and oligomerization. The mixture of alcohols and oligomer product from hydration reaction is separated and the bottom stream from separator is routed to oligomerization reaction zone in a controlled quantity as selectivity enhancer. Both the reaction zones are operated at different conditions. The product from oligomerization zone is further separated in to lighter and heavier components. Each reaction zone may comprise series of reactors filled with acidic catalysts comprising ion exchange resins.

The present invention relates to a method of producing bio-based homoserine lactone and bio-based organic acid through hydrolysis of O-acyl homoserine produced by a microorganism in the presence of an acid catalyst. According to the present invention, O-acyl homoserine produced by a microorganism is used as a raw material for producing 1,4-butanediol, gamma-butyrolactone, tetrahydrofuran and the like, which are industrially highly useful. The O-acyl homoserine produced by a microorganism can substitute conventional petrochemical products, can solve environmental concerns, including the emission of pollutants and the exhaustion of natural resources, and can be continuously renewable so as not to exhaust natural resources.
