Abstract:
Embodiments disclosed herein relate to a process for the oligomerization of olefins, the process including at least one olefin feedstream that includes ammonia and contacting the at least one olefin feedstream with a liquid including alkaline water to remove at least a portion of the ammonia to produce at least one treated olefin feedstream and subsequently contacting the at least one treated olefin feedstream with a catalyst under oligomerization conditions to produce an oligomer product. In several embodiments disclosed herein, the at least one olefin feedstream includes one or more C 3 -C 15 olefins, preferably, C 3 -C 5 olefins, any isomer thereof, one or more paraffins having the same or different carbon number as the olefins, and mixtures thereof.
Abstract:
Techniques, systems, apparatus and material are disclosed for regeneration or recycling of carbon substances into renewable fuel and materials. In one aspect, a method of recycling carbon to produce a renewable fuel can include harvesting carbon donors, such as carbon dioxide (CO2), emitted from an agricultural process. Hydrogen donors, such as from biomass waste, can be dissociated under an anaerobic reaction to produce hydrogen. The harvested carbon dioxide can be reacted with the waste-produced hydrogen under pressure and temperature to generate a renewable fuel, such as methanol fuel.
Abstract:
The invention is directed a process to prepare a catalyst composition comprising a gamma-alumina carrier, metal nano-particles, wherein the metal is selected from silver, copper or gold, and an additive selected from the group of an alkaline metal compound as present as an oxide or hydroxide of the alkaline metal wherein: in a first catalyst preparation step a gamma-alumina carrier is contacted with an aqueous solution comprising a salt of the alkaline metal in an impregnation step to obtain a loaded alumina carrier,and wherein the weight of alkaline metal as deposited on the alumina surface of the alumina carrier is greater than the weight of alkaline metal as present in the final catalyst composition, drying the loaded alumina carrier and subjecting the dried loaded alumina carrier to a calcination step, loading the silver, copper or gold metal to the calcined loaded carrier in a second catalyst preparation step by contacting with an aqueous solution of a silver, copper or gold metal salt and drying to obtain the catalyst.
Abstract:
The present invention relates to polyglycerol partial esters of linear, unsubstituted carboxylic acids with the provisos that the polyglycerol obtained by hydrolysis or alcoholysis of the polyglycerol partial ester comprises an average degree of polymerization of from 2 to 8 and the polydispersity index of said polyglycerol is greater than 0.75.
Abstract:
The present invention relates to a metal oxide catalyst represented by the following Formula 1, which is useful for the production of linear polyglycerol via etherification of glycerol, and a method for its preparation thereof: [Formula 1] (CaO)a?Ca12Al14O33)100-a wherein a refers to a weight ratio of CaO based on 100 parts by weight of the total catalyst. When the alkaline binary metal oxide catalyst according to the present invention is used in the glycerol etherification, it can produce a large amount of linear polyglycerol glycerol. Therefore, the metal oxide catalyst prepared according to the present invention can be effectively used in the production of polyglycerol suitable as cosmetic or food additives.
Abstract:
The present invention relates to processes for making dibutyl ethers using aqueous ethanol optionally obtained from a fermentation broth. The dibutyl ethers so formed find use as additives for fuels, including transportation fuels.
Abstract:
A diverse set of tubulin binding agents have been discovered which are structurally characterized, in a general sense, by a semi-rigid molecular framework capable of maintaining aryl-aryl, pseudo pi stacking distances appropriate for molecular recognition of tubulin. In phenolic or amino form, these ligands may be further functionalized to prepare phosphate esters, phosphate salts, phosphoramidates, and other prodrugs capable of demonstrating selective targeting and destruction of tumor cell vasculature.
