Patent NL-8006656-A (NL)
Title: Catalytic conversion of a gas (mixt.) - in a reactor contg. a fixed bed of one catalyst and a fluidised bed of another catalyst
IPC: C07C1/04
Filed: 1980-12-08
Abstract: Process for chemical conversion of a gas or gas mixt. comprises contacting the gas (mixt.) in a reactor with a solid bed or at least 1 catalyst and a fluidised bed of at least one other catalyst. Pref. reactor comprises a series of hollow concentric chambers with gas-permeable walls contg. solid particles of a first catalyst, with intermediate concentric channels contg. the fluidised bed catalyst. Process allows successive conversion reactions to be carried out in a gas (mixt.) by economical means, using a single reactor. Problems of separating components in mixed catalyst systems or inactivation of one component whilst regenerating the other, found in some prior art processes, are overcome. Process is esp. useful for conversion of a synthesis gas mixt., first over a cobalt catalyst to form a hydrocarbon stream which is then converted into aromatic hydrocarbons over a zeolite catalyst; for Fischer-Tropsch conversions of synthesis gas; and direct conversion of low hydrogen synthesis gas via methanol, e.g. using a ZnO/Cr203 methanol synthesis catalyst and a zeolitic catalyst.

Date Jan. 23, 1992.A non-pneumatic supporting wheel includes a central part and a wheel-rim which is supported by the central part. The wheel-rim has an outer wheel-rim part which is intended to roll against an underlying surface, and an inner wheel-rim part which is located radially inwards of the outer wheel-rim part. At least the inner of the two wheel-rim parts is constructed from a plurality of curved, elongated elements which consist of a resilient material and which are spaced in the circumferential direction of the wheel. When seen in a section taken diametrically through the wheel, each of these elements presents parts which are curved in opposite directions. For the purpose of taking-up forces which act substantially radially between the wheel center and the region of the wheel in contact with the underlying surface when the wheel is subjected to load, the elements are elastically yielding in the radial direction of the wheel during increased bending of the elements. The circumferentially spaced and bendable elements are constructed so that both the sum of the bending of each small longitudinal section of the elements when the elements are subjected to load in the radial direction of the wheel and the sum of the product of the bending of each small section and the distance of this section from the underlying surface when the wheel is subjected to normal load is at least essentially zero.
