Removal of H₂S from coal gas: effect of various parameters on the desulfurization efficiency

After a decade of extensive research, a number of solid sorbents have been identified as being suitable for the high-temperature removal of H₂S from coal gas. Current activities are aimed at the development of a ...

Survey of Desulfurization Processes for Coal Gas

An overview is given of recent developments in the field of regenerative, high temperature, coal gas desulfurization. The results of a wide variety of sorbents and reactor types either tested on lab-, bench- a...

Cleaning of Hot Producer Gas in a Catalytic Adiabatic Packed Bed Reactor with Periodic Flow Reversal

To use the product gas of a biomass gasification unit in, for instance, gas engines, its tar content must be reduced to less then 100 mg/Nm³ [1]. A novel technology has been tested which is characterised by perio...

Development of a Small Integrated Pilot Plant for Flash Pyrolysis of Biomass

A continuous test-unit for the flash pyrolysis of biomass to bio-oil, with a throughput of 10 kg pulverised biomass per hour, has recently been developed at the University of Twente. The apparatus is now under...

The Rotating Cone Flash Pyrolysis Reactor

The velocity of nearly spherical mono-sized PVC powder in a cold-flow rotating cone reactor (top angle π/3 rad, height 0.43 m) was measured under variation of the particle diameter (140 –780 μm) and the cone r...

Photoregulation of Polymer Conformation

The flow of energy from the Sun out into the universe, absorbed by day and radiated out at night, has brought about on Earth the molecular ordering from which life originated [1]. The same flow has since suppl...

Light Scattering by Polymer Networks

Non-crystalline polymer networks, whether swollen or not, may exhibit interchain structuring effects due to incompatibility of various parts of the chains (e.g., backbone-side chain or blocks along a copolymer...

Polymorphism of Alkyl Sulphate Soaps

ALKYL sulphate soaps NaSO₄C_nH_{2n + 1}, like the fatty acids and alcohols, may be expected to have a tendency to join together the hydrophylic groups of neighbouring molecules. In the crystalline state, this tendenc...

Moulded polystyrene scintillators

Luminescent solid solutions of 1-4 diphenyl-butadiene (DPB), 1-6 diphenyl-hexatriene (DPH), and 1-1-4-4 tetraphenyl-butadiene (TPB) in polystyrene were made by a process of “slow” injection moulding. It turns ...
