摘要:
The present invention relates to an integrated process for obtaining chemicals from renewable organic material (100) by hydrotreatment comprising the steps of feeding the renewable organic material (101) into at least one pre-treatment unit (102) for removing any material (117) not suitable as feedstock for subsequent hydrotreatment, feeding the pre-treated organic material from the at least one pre-treatment unit (102) to at least one hydrotreatment unit (103) for providing gas-oil like hydrocarbons (107) from the pre-treated organic material in the presence of hydrogen and a catalyst, feeding the gas-oil like hydrocarbons (107) from the at least one hydrotreatment unit (103) into at least one steam cracker furnace unit (108) for thermal cracking for providing a cracked product mixture (109); feeding the cracked product mixture (109) into at least one steam cracker fractionation unit (110) for separating the cracked product mixture into high value chemicals (111), in particular ethylene, propylene, butadiene and BTX aromatics, hydrogen (112), fuel gas (113) and fuel oil (114), wherein at least part of the hydrogen (112) from the at least one steam cracker fractionation unit (110) is recycled back to the at least one hydrotreatment unit (103).
摘要:
The present invention relates to wash oil for use as an antifouling agent in gas compressors, in particular in cracked gas compressors, comprising at least one compound according to formulae (II) wherein the moieties R 2 and R 3 are selected from a group comprising linear or branched C 1 -C 20 -alkyl, C 3 -C 10 -cycloalkyl and linear or branched C 1 -C 10 -alkyl substituted C 3 -C 10 -cycloalkyl and C 6 -C 12 aryl and C 1 -C 10 -alkyl substituted C 6 -C 12 aryl and wherein said moieties can be interrupted by oxygen or nitrogen and wherein said moieties can be functionalised with hydroxyl groups or amino groups and wherein said moieties can be the same or different. The invention relates also to the use of such wash oil as anti-fouling agent.
摘要:
The present invention is directed to a process for producing a modified olefin polymer having increased melt strength in an extruder. The process comprising the steps of: (A) contacting a stream comprising particles of an olefin polymer with a vapour stream of a functionally unsaturated compound in vapour phase thereby producing a first mixed stream; (B) passing the first mixed stream to an extruder; (C) melting the polymer particles of the first mixed stream in the extruder; (D) introducing a stream of a free radical generator either into the first mixed stream or into the extruder; and (E) extruding the first mixed stream and the free radical generator at a temperature which is greater than the decomposition temperature of the free radical generator and the melting temperature of the olefin polymer but less than the decomposition temperature of the olefin polymer thereby producing the modified olefin polymer in the extruder.
