Waste Plastic Liquefaction Technology of Sapporo Plastic Recycle Corporation and Approach to Feedstock Recycling in near Future

The Proceedings of the Symposium on Environmental Engineering (2002)

Eiichi Sugiyama Hidetoshi Ibe Masaaki Fukushima Katsumi Shimura Eiichi Ōno

Sapporo Plastic Recycle Corporation has been operating a commercial waste plastic liquefaction plant, over two years safely since April 2000,when the containers and packaging recycling law on plastic packages was introduced in Japan. During this operation, we encountered initial troubles such as corrosion, blockade caused by HCl gas generated from PVC, and organic acid generated from PET, but cleared them one by one, and achieved continuous operation favorably. We solved this problem caused by organic acid generated from PET by adding alkali into the process. High conversion rate of oil from waste plastic was achieved by special designed degradation contrivance that is rotary kiln type with triple vessel structure. We would like to promote feedstock recycling by the product oil of this process to oil refinery first of all.

210 The Progress to Feedstock Recycling in Large Scale Waste Plastic Liquefaction Plant : For the Construction of True Recycle Society

The Proceedings of the Symposium on Environmental Engineering (2005)

Sapporo Plastics Recycling Co., Ltd. (SPR) and Rekiseikouyu Co., Ltd. had developed and put to practical use of the liquefaction plant for municipal waste plastics including PVC and PET, and maintaining a high rate of making to oil, and waste plastic oil making technology to have done considerable results though the processing of making to these oil plant had passed five years or more since it began to have driven. The feedstock recycling that returns the generation light oil of these plant of making to oil as a raw material of the oil refinery (Japan Energy Corporation) is started that becomes the first in the world in April, 2004, and this also continues the stability driving well. In addition, progress to the technology that does the feedstock recycling can expect the waste plastic cracked oil in the future.

Development of Dechlorination Technology for the Liquefaction Recycling of Municipal Waste Plastics

一般市民から資源ごみとして出される使用済みプラスチック製容器包装の熱分解油化技術において，ポリ塩化ビニル (PVC) 等の塩素含有プラスチックの熱分解によって脱離する塩素の効率的処理が，再生製品の品質改善の課題となっている。本研究では二軸押出機方式による脱塩素の滞留時間が短いことに着目し，一軸押出機を使用した脱塩装置の開発を行い，一軸押出機は二軸押出機と同様に脱塩素率が高く，脱塩素時間 (滞留時間) も短いという結果を得た。本実験結果を基に10倍にスケールアップした一軸押出機 (脱塩装置) を使用した商用熱分解油化プラントを2000年北海道札幌市東区中沼町に建設し，2009年度で運転10年目を迎えている。使用済みプラスチック製容器包装油化リサイクルにおける脱塩素技術の開発成果を報告する。

Development of a reaction system for the direct synthesis of ethanol from carbon monoxide and hydrogen with homogeneous ruthenium catalyst in liquid phase.

均一ルテニウム触媒を用いたCO/H2からのエタノールの液相直接合成のための反応方式の開発を行った. 本反応は220～240℃, 40～50MPaの条件下で行われ, 主な副生成物はメタノール, プロパノール, 酢酸メチル, 酢酸エチルおよびメタンである.これらの反応生成物がいずれも低沸点であることに着目して, 高沸点の反応溶媒を用い, 触媒液を反応器に保持しておいて合成ガスだけを連続供給し, 反応生成物を未反応ガスでストリップして反応系外に取り出す反応方式を研究し, 適切な条件下においてこの反応方式が本反応に有効であることを見いだした.この反応方式では反応生成物の他に触媒成分の一部が揮散することがわかり, この揮散に見合う量の触媒を反応器に補給することによって反応を安定化することができた.その結果, 約40時間にわたってエタノールのSTY110±10kg・m-3・h-1, 選択率60±2%という反応成績を得た.

PVCとPETを含む容器包装混合廃プラスチック油化処理技術において，外熱式ロータリーキルンを使用した熱分解装置の開発を行い，下記の結果を得た。(1)PVCとPETを含む混合廃プラスチックの熱分解油収率は，3P(PE, PP, PS) の熱分解油収率に比べて約20～30wt%低く，熱分解残渣は約20wt%高い。(2)ロータリーキルンは，連続処理運転よりもセミバッチ処理運転 (脱塩後の溶融プラ投入を一時停止し熱分解・残渣排出) が熱分解油の収率が高い。(3)脱塩素プロセスと熱分解プロセスを分離し，脱塩素と熱分解の同時並行処理を行い，熱分解の効率化を図ることができた。(4)脱塩素から熱分解まで装置を垂直に配置し，ポンプ等の移送設備を使用しない重力移送方式を採用し，溶融プラの流動性悪化に起因したトラブル発生を防止することができた。(5)廃プラ熱分解油は石油化学原料化が可能であることが明らかとなり，フィードストックリサイクルの対象油を軽質油から分解油に広げることが可能となった。
