    • A hydrocarbon synthesis process (10) includes feeding gaseous reactants (18) into a slurry bed (14), allowing the gaseous reactants (18) to react catalytically, thereby to form liquid and gaseous hydrocarbon products, and subjecting a product mixture comprising liquid product and catalyst particles in a filtration stage to filtration, by passing the liquid product through a filtering medium (30) to separate catalyst particles from the liquid product. The gaseous products are withdrawn (23) and cooled to form a multi-phase product which is separated to produce at least a hydrocarbon condensate stream (88) and a tail-gas stream (84). At least a portion of the hydrocarbon condensate stream (88) is treated (96) to remove oxygenated components therefrom, producing a backflush condensate. From time to time, the filtering medium (30) of the filtration stage is backflushed by passing the backflush condensate through the filtering medium (30).
    • 烃合成方法(10)包括将气态反应物(18)进料到淤浆床(14)中,使气态反应物(18)催化反应,由此形成液态和气态烃产物,并将包含液态产物 和过滤阶段中的催化剂颗粒通过使液体产物通过过滤介质(30)以从液体产物中分离催化剂颗粒来过滤。 将气体产物抽出(23)并冷却以形成多相产物,将其分离以产生至少一种烃冷凝物流(88)和尾气流(84)。 处理(96)至少一部分烃冷凝物流(88)以从其中除去氧化组分,产生反吹冷凝物。 有时通过使反冲洗冷凝物通过过滤介质(30)来对过滤阶段的过滤介质(30)进行反冲洗。
