Abstract: The invention provides a process for converting a paraffinic feedstock comprising at least 50 wt % of compounds boiling above 370° C., a paraffin content of at least 60 wt %, an aromatics content below 1 wt %, a naphthenic content below 2 wt %, a nitrogen content below 0.1 wt %, and a sulphur content below 0.1 wt %, comprising: (a) reacting the feedstock with hydrogen at a temperature between 175 and 400° C. and a pressure between 20 and 100 bar using a catalyst comprising 0.005 to 5.0 wt % of a Group VIII noble metal on a carrier comprising 0.1-15 wt % zeolite beta and at least 40 wt % amorphous silica-alumina (b) withdrawing the effluent (c) subjecting the effluent to a fractionation step to form a heavy fraction, an intermediate fraction, and a light fraction; and (d) providing at least part of the heavy fraction to the reaction zone.

Abstract: The present invention provides a process for the conversion of a paraffinic feedstock that comprises at least 50 wt % of compounds boiling above 370° C. and which has a paraffin content of at least 60 wt %, an aromatics content of below 1 wt %, a naphthenic content below 2 wt % a nitrogen content of below 0.1 wt %, and a sulphur content of below 0.1 wt %, which process comprises the steps of: (a) providing the feedstock to a reaction zone, where it is contacted with hydrogen at a temperature in the range of 175 to 400° C. and a pressure in the range of 20 to 100 bar in the presence of a catalyst comprising 0.005 to 5.0 wt % of a Group 8 noble metal on a carrier, the carrier comprising 0.

Abstract: The invention relates to a method for the catalytic conversion of organic carbonate to the corresponding alcohol, wherein the organic carbonate is contacted with alcohol and/or water in the presence of a zinc supported catalyst.

Abstract: A fluid pressure regulator is provided having a housing with an inlet and outlet for fluid, a valve located movably inside the housing and provided with a fluid transport member to allow passage of fluid from the inlet to the outlet. The regulator also has a pressure setting member and a space defined by one end of the valve and an end wall of the housing. The valve is moveable relative to the housing in response to a change in pressure within the space between a first position which at least partially aligns the fluid transport member with each of the inlet and the outlet and a second position in which there is no alignment of the fluid transport member with at least one of the inlet and the outlet. A passage is provided in open communication with the space and one of the inlet, the outlet, and the transport member. Methods of using the pressure regulator are also provided.

Abstract: A method for the catalytic conversion of organic carbonate, wherein organic carbonate is contacted with alcohol and/or water in the presence of a lanthanum catalyst comprising at least about 7 wt. % of lanthanum supported on a support.
