摘要:
The system for driving a reciprocating compressor comprises a reciprocating compressor (1) with a crankshaft (31). A Stirling engine (50) is drivingly connected to the crankshaft (31) of the reciprocating compressor (1). A heat source (71), for example a waste heat source, provides heat to the hot end of the Stirling engine. Heat is partly converted into mechanical power to drive the reciprocating compressor (1).
摘要:
A process to efficiently convert organic feedstock material into liquid non-oxygenated hydrocarbons in the C5 to C12 carbon skeleton range is disclosed. The process can utilize gaseous, liquid or solid organic feedstocks containing carbon, hydrogen and, optionally, oxygen. The feedstock may require preparation of the organic feedstock for the process and is converted first into a synthesis gas containing carbon monoxide and hydrogen. The synthesis gas is then cleaned and conditioned and extraneous components removed, leaving substantially only the carbon monoxide and hydrogen. It is then converted via a series of chemical reactions into the desired liquid hydrocarbons. The hydrocarbons are suitable for combustion in a vehicle engine and may be regarded a replacement for petrol made from fossil fuels in the C5 to C12 carbon backbone range. The process also recycles gaseous by-products back through the various reactors of the process to maximize the liquid hydrocarbon in the C5 to C12 carbon skeleton range yield.
摘要:
Expanded articles of biodegradable plastic material are produced by agglomerating expanded particles with density from 0.1. to 0.003 g/gm 3 and size from 0.5 to 10 mm of diameter, made of a material comprising:
from 50 to 95% by weight of thermoplastic starch; from 0.5. to 45% by weight of at least one thermoplastic polymer; from 2 to 20% by weight of water; subject to a heating treatment and/or a treatment with at least one coating agent in order to modify their surface so that they can steady interact when brought into intimate contact.
摘要:
The invention relates to a method for producing NOx reductants by injecting hydrocarbon into a diesel engine's combustion chamber during the expansion cycle. The secondary injected hydrocarbon is formed, under appropriate conditions, into oxygenates and olefins that are suitable for reducing NOx species in the presence of conventional exhaust catalysts. The appropriate injection timing is obtained by referring to a calibration obtained by direct engine measurements.

An ethane-rich stream is reduced in pressure below the inlet pressure to a pyrolysis furnace, vaporized in heat exchange relationship with a process stream, recompressed, and passed to the pyrolysis furnace.
