Async queue in Laravel 5.8

I'm building an app to generate catalogs. Data I need to load are often more than 50mb so to do not disrupt user experience I tried to use a queue in Laravel.

I have a job class:

<?php

namespace App\Jobs;

use Illuminate\Bus\Queueable;
use Illuminate\Queue\SerializesModels;
use Illuminate\Queue\InteractsWithQueue;
use Illuminate\Contracts\Queue\ShouldQueue;
use Illuminate\Foundation\Bus\Dispatchable;
use Illuminate\Http\Request;


use PDF;
use App\Jobs\ProcessCatalog;

class ProcessCatalog implements ShouldQueue
{
    use Dispatchable, InteractsWithQueue, Queueable, SerializesModels;

    protected $id;
    /**
     * Create a new job instance.
     *
     * @return void
     */
    public function __construct($id)
    {
        $this->id=$id;
    }

    /**
     * Execute the job.
     *
     * @return void
     */
    public function handle()
    {
             //code which generate catalogs
    }
}

I tried to run this with:

public function generateC() {

    ProcessCatalog::dispatch(1);

return 'it works'; 
}

and everything works fine when the queue is sync but when I QUEUE_DRIVER=sync to QUEUE_DRIVER=database everything seems that work but catalog never generated...

I need to run queue async? What is the best way to do that?
