Systems and methods are provided for catalytically dewaxing a diesel boiling range feed. In some aspects, catalytic dewaxing can be performed at low hydrogen treat gas rates and/or low hydrogen purity conditions. In other aspects, the systems and methods can allow for distillate dewaxing while reducing or minimizing the amount of equipment required.

The present invention relates to new crystalline zeolite SSZ-52x prepared using a quaternary ammonium cation templating agent, for example, having the structure:

##STR00001##

wherein X.sup.− is an anion which is not detrimental to the formation of the SSZ-52x. SSZ-52x is useful as a catalyst and shows improved durability, particularly with regard to NO.sub.x conversion.

Catalytic conversion of ketoacids is disclosed, including methods for increasing the molecular weight of ketoacids. An exemplary method includes providing in a reactor a feedstock having at least one ketoacid. The feedstock is then subjected to one or more C—C-coupling reaction(s) in the presence of a catalyst system having a first metal oxide and a second metal oxide.

A Hydro Disambiguative Catalytic Donor Recombination process and apparatus that uses Water, Sunlight (for energy) and any Organic liquid carbon donor source (Plant (vegetable oils) and Animal Fat (fortified butter or ghee) to produce flammable fuel consisting of C.sub.1 to C.sub.8 Hydrocarbons, and we call this gas as Organic Petroleum Gas (NPG), which has the same composition as a petroleum gas obtained from fossil source.

This disclosure relates to the field of renewable oil compositions and to the use of renewable oil compositions for production of hydrocarbon compositions, which can be used for traffic fuels and other solutions. An exemplary composition contains free fatty acids and triglycerides, in a concentration of free fatty acids from 15 wt-% to 80 wt-% and a remainder being predominantly triglycerides. A method for producing hydrocarbons from a renewable oil feedstock, in which the feedstock which contains free fatty acids from 15 wt-% to 80 wt-%, and a remainder being predominantly triglycerides, is subjected to a pretreatment process followed by a hydrotreatment process for obtaining hydrocarbons.

The invention is concerned with the production of 1-hexene and octenes from ethene. 1-Butene is optionally also to be produced. The problem addressed by the present invention is that of developing a process for producing 1-hexene from ethene by MTHxE etherification to achieve better chemical utilization of the employed carbon atoms. This problem is solved by catalytic retrocleavage of MTHxE into the C.sub.6 olefins and the alcohol, reuse of the alcohol in the etherification and reaction of the obtained C.sub.6 olefins with ethene to afford C.sub.8 olefins. In this way the alcohol is not lost from the process but rather is internally recirculated as a derivatizing agent. The less attractive C.sub.6 olefins from the cleavage product are upgraded to octene with further ethene in order to provide a further commercial product.

An absorbent article comprising a composition, said composition comprising a metathesized unsaturated polyol ester, said metathesized unsaturated polyol ester having one or more of the following properties: (i) a weight average molecular weight of from about 5,000 Daltons to about 50,000 Daltons; (ii) an oligomer index from greater than 0 to 1; (iii) an iodine value of from about 30 to about 200.

The present invention discloses a catalytic process for the manufacture of hydrogen and hydrocarbons simultaneously in the same reactor from renewable source, i.e. lipids, glycerides and fatty acids from plant, animal or algae oil, where in the multiple unstaurations in the renewable feedstock and the catalytic intermediates produced in the process from renewable feedstock is converted catalytically using simultaneous combination of in-situ occurring reactions. These in-situ occurring reactions are simultaneous combination of hydroconversion, reforming and water gas shift reactions wherein the reaction is performed in the presence of one or more metal sulfides form of metals of Group VI and/or Group IX and/or Group X elements, specifically comprises of one or more active metal combinations such as Co, W, Mo, Ni, P, with Pt, Pd encapsulated inside sodalite cages for prevention against poisoning from sulfur based compounds. The hydroconversion comprises of reactions in presence of hydrogen such as hydrocracking, dehydrogenation, dehydrocyclization, hydrodeoxygenation, hydrodesulfurization, hydrodenitrogenation, decarboxylation, decarbonylation, cyclization and aromatization reactions. The catalyst along with the active metals also includes porous silica-alumina, zeolite, silica, alumina, silicoaluminophosphates or a combination of two or more thereof used as support for the above said process. These catalysts are loaded in a graded beds (two or more beds of different catalyst mixtures) or simultaneously (mixture of different catalyst systems) and reacted specifically at lower temperatures than the steam reforming conditions i.e. at pressure from 10 to 150 atmosphere, average temperature of the catalytic bed from 250° C. to 500° C., space-velocity of from 0.5 h.sup.−1 to 8 h.sup.−1, and hydrogen to feed ratio of from 300 NL of hydrogen/L of feed to 3500 NL hydrogen/L of feed., Initially hydrogen gas is supplied for conversion of the renewable feed stocks, as the reaction process the hydrogen consumed during the conversion of plant, animal or algae oil into hydrocarbons is balanced from the in-situ reactions such as reforming, dehydrogenation, water gas shift etc occurring during the same process. This production of hydrogen makes the entire process refinery independent and more economical and sustainable. Along with hydrogen the renewable feed stock is also converted into hydrocarbons ranging between C1-C24 carbon number, comprising of n-paraffins, isoparaffins, cyclo paraffins, naphthenes, and aromatics and polynuclear aromatics.

A method is disclosed for reducing fouling in catalytic cracking. The method includes subjecting a recycled fossil-based feedstock to a heat treatment, evaporating the heat-treated feedstock, hydrotreating resulting evaporation distillate and performing catalytic cracking of the hydrotreated distillate in a presence of a solid acid catalyst.

The present technology relates to hydrocarbon fuels comprising renewable content. More particularly, the technology relates to manufacture of renewable diesel for potential use as aviation turbine fuel blendstock.
