Abstract:
A photocatalytic process is disclosed for the reduction of carbon dioxide and water. The process comprises reacting carbon dioxide and water in the presence of a photocatalytic composition that is irradiated with electromagnetic radiation having a wavelength in the range of from 200 to 700 nm. The photocatalytic composition is capable of chemisorbing carbon dioxide.
Abstract:
Disclosed is a pyrolysis product of a biomass material. This product, referred to as bio-crude, has a total acid number (TAN) of less than 10, and is suitable for processing in stainless steel equipment. A process for making the bio-crude comprises pyrolysis of a biomass in the presence of a particulate catalyst. The TAN of the bio-crude may be reduced further by reducing the bio-crude with coke and or CO produced in the process.
Abstract:
The present invention relates to a microporous crystalline material of zeolitic nature, called ITQ-1A, to the process for its preparation and its use in processes of separation and transformation of organic compounds. In the roasted and anhydrous stage, the chemical composition of the material corresponds to the empirical formula: x(M1/nXO2):yYO2:SIO2, wherein x has a value smaller than 0.02 and may equal 0; y has a value smaller than 0.04 and may equal 0; m is H or an inorganic cation with the charge +n; X is a chemical element with an oxidation status +3 (Al, Ga, B, Cr) and Y is a chemical element with an oxidation status +4 (Ti, Ge, V). When x = 0 and y = 0, the material may be described as a new polymorphe form of microporous silica. The material of this invention is characterized also by its X ray diffraction pattern. The process for the preparation of said zeolite is characterized by the use of one or a plurality of organic additives in a reaction mixture which is crystallized through heating.

Abstract:
A process is disclosed for fluid catalytic cracking of oxygenated hydrocarbon compounds such as glycerol and bio-oil. In the process the oxygenated hydrocarbon compounds are contacted with a fluid cracking catalyst material for a period of less than 3 seconds. In a preferred process a crude-oil derived material, such as VGO, is also contacted with the catalyst.

Abstract:
A process is disclosed for mild hydro-conversion of oxygenated hydrocarbon compounds. The oxygenated hydrocarbon compounds are contacted with a hydro- conversion catalyst material at a reaction pressure below 100 bar. Preferred oxygenated hydrocarbon compounds are those obtained by the liquefaction of biomass. In a specific embodiment the process is used for production of normal alkanes by hydrotreating mixtures of triglycerides (or compounds derived-from triglycerides, including free fatty acids) and vacuum gasoil.
