ScheduledthreadPool() function can be used multiple times? will it make difference in the processing of threads

scheduledThreadPool = Executors.newScheduledThreadPool(Runtime.getRuntime().availableProcessors());

scheduledThreadPool1 = Executors.newScheduledThreadPool(Runtime.getRuntime().availableProcessors());

while(mNumberOfChatToGenerate!=0){
  WebChatTask chatWork = new WebChatTask(mConfig,chatId++); 
  System.out.println("Current delay : " + mCurrDelay);
            scheduledThreadPool.schedule(chatWork, mCurrDelay * chatId, TimeUnit.SECONDS);

  mNumberOfChatToGenerate--;

  WebChatTask chatWork1 = new WebChatTask(mConfig,chatId++); 
  scheduledThreadPool1.schedule(chatWork1, mCurrDelay * chatId, TimeUnit.SECONDS);
  mNumberOfChatToGenerate--;
}
