The present invention is related to the isomerization process in which a light naphtha stream comprising of paraffinic (mono and single branched), naphthenic and aromatic hydrocarbons in the range of C-Cis contacted with the solid catalyst in multiple reaction zones and in presence of hydrogen to produce high octane gasoline predominantly comprising of paraffins (single and di-branched) and naphthenes. The process scheme comprises of more than one isomerization reaction section operating at different temperatures and other operating conditions. The catalyst employed in these reaction sections is a high coordination sulfated mixed metal oxide catalyst which contains at least one noble metal and sulfated zirconia in addition to the other components. The process of the present invention also comprises more than one fractionation section and recycling of a particular stream to the reaction zone for improving the isomerization of light naphtha.

The present invention provides a process of preparing a high coordination sulfated mixed metal oxide catalyst. The process comprises mixing specific ratios of alumina and zirconia mixtures at specific particle size limits which do not exceed 37 &#x3bc;m, in the presence of a combination of &#x3b1;-amino acids, i.e., non-polar side chains and basic side chains having molecular weight less than 250, nitric acid (HNO3) and sulfuric acid (H2SO4) at a pH range of 1.5 to 3.8 at temperatures below 30&#xb0; C. The catalysts have a high conversion towards hydrocarbon isomerization reaction while concurrently having crushing strength in range of 2.0 daN and 5.0 daN, allowing for efficient commercial application.

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 process for etherification of mixed olefinic light naphtha boiling in the range of C5-90&#xb0; C. cut with simultaneous minimization of unreacted methanol concentration in the product. The etherification of mixed olefinic light naphtha produces the high octane blending component which can be blended directly in the gasoline pool without any recovery of the feed oxygenates like methanol, ethanol etc. which conventionally uses energy intensive separation processes.

The present invention relates to a process for production of oligomer products from olefinic C4 feed stocks comprising isobutene, butenes, butanes, butadienes and mixture thereof. Particularly, the present invention relates to a process for the preparation of oligomers using olefinic C4 feed stock in presence of tertiary butyl alcohol (TBA) and iso propyl alcohol (IPA).
